  • Biodegradation is one of the solutions to the problem of "plastic pollution"
    • Bio-Based compostable and degradable plastics: come from plants and can reduce carbon emissions. Such as: polylactic acid, PHA. etc.
    • Petroleum based compostable degradable plastics: reduce solid waste pollution and return to nature through composting degradation. Such as: PBAT, PBS, PCL, etc.
  • Polylactic acid is a biodegradable material that uses renewable plant resources such as corn and straw to obtain high purity lactic acid through fermentation, and then polymerize to obtain polylactic acid.
    After being discarded, it can be degraded by composting and finally generate carbon dioxide and water. It is an ideal green polymer material.
  • Compared with petroleum based materials, the carbon dioxide emissions of Biodegradable Material PolyLactic Acid (PLA) can be reduced by 60%, and non renewable energy consumption can be reduced by 50%. It has low VOC and can be recycled and reused during the life cycle.
  • The modified polylactic acid material has good mechanical properties and heat resistance, and at the same time has good processability. The injection molding and molding processes commonly used in petroleum based plastics can be applied.

Certification of Biodegradable Materials

Certification of Biodegradable Materials

Testing Organization:
The European Union's certification standard EN13432, the certification bodies AIB VINCOTTE and DIN CERTCO, are in Belgium and Germany respectively. China's standard GB/T20197 2006. American standard DSTMD640, certification body BPI. Japanese standard JIS K 6953, certification agency JBPA. Australia also has standards and related certification bodies.

Test Conditions:
Under composting conditions, the materials can be converted into carbon dioxide and water within 180 days through the action of microorganisms. The test includes four aspects: 1. Chemical composition analysis, 2. Disintegration test, 3. Biodegradation test, 4. Environmental toxicity test.

Good Security:
Polylactic acid has good food safety. It takes a long time to completely degrade into carbon dioxide and water in a natural environment that does not meet the composting conditions, but no environmentally harmful substances are produced in the process.

Environmental Advantages:
The environmental protection advantage of polylactic acid is also reflected in that even when polylactic acid is only burned or landfilled without composting conditions, it is more environmentally friendly than conventional plastics.
The products of complete combustion of polylactic acid are carbon dioxide and water, which do not produce harmful pollutants; although the degradation rate of landfill is slow, it does not produce harmful substances, does not pollute groundwater, does not damage plant growth, does not waste arable land, and can be recycled.

Outstanding advantages in the industry of bio-based degradable materials

Semi-Durable: Through modification to solve the defects of polylactic acid itself and extend the shelf life, it has passed a number of product tests. Realize the application in the high-end semi-durable products market.

High Strength: Polylactic acid has poor toughness, hard and brittle texture, insufficient elasticity and flexibility, limited strength and modulus, and unstable degradation rate. A single polylactic acid material is not suitable for applications that require high mechanical properties. Through a variety of physical and chemical modification methods, the above-mentioned shortcomings are fully overcome, and the cost is reduced as much as possible, and the mechanical properties and processing properties are improved.

High Heat-Resistance: Polylactic acid has poor heat resistance. The temperature resistance of materials/products is increased to more than 100° through modification. A mold temperature machine is required for injection molding, and the heat resistance can be exerted after sufficient crystallization in the mold. In order to adapt to the domestic injection molding conditions, the modified material with low mold temperature and high heat resistance has been developed, which can alleviate the problem of narrow processing window.

Processing Guide

1. Mold Requirements
1.1. N2001 material is a bio-based material. Based on the properties and processing properties of biomaterials, the mold steel is required to have good strength, toughness and resistance to deformation at high temperatures, and the surface hardness is not less than 50HRC. It is recommended to use 5136 or K80 steel for making molds.
1.2. The mold requires water cooling and heating. The runner design of the water circuit must ensure that the mold has better cooling and heating capabilities. It is recommended that each block of the front and rear molds ensure at least two sets of runners on the basis of ensuring the strength. If the product is not required to be heat-resistant, the mold temperature should be controlled below 30íŠ when injection at low moldtemperature; if the product is required to be heat-resistant, then it is necessary to add a heat insulation board (epoxy resin material or glass fiber material) to prevent the heat loss of the mold, so that the actual temperature of the mold is controlled between 95-100íŠ.
1.3. If the mold needs to be remade, the dimensional accuracy of the mold parting surface is required to be within ±0.02mm to ensure smooth exhaust without flashes.
1.4. In order to improve the efficiency of injection molding, the design of the nozzle sleeve should be short and large taper design. The ejection of the mold is uniform. In order to prevent product deformation during the ejection process, it is not recommended to design a single ejection.
1.5. PLA material is a heat-sensitive polymer material, and it should not be in a molten state for a long time. If the melting time of the material exceeds 5 minutes, it is recommended to clean the material 3-5 times before re-plasticizing.

2. Material Drying
The material has been dehumidified and dried before leaving the factory, the water content is less than 200ppm, and it is protected in aluminum foil bags or rigid plastic bags. The material needs to be packaged in good condition before use, and it needs to be sealed quickly after use. The material after long-term unsealing needs to be dried at 80íŠ for 4 hours before use. Otherwise, after the material absorbs water, the injection molding is likely to have greater fluidity, the product will become brittle, and the surface of the product will have silver streaks and water streaks. It is recommended to use a desiccant dryer or a blast dryer with the same function for the drying of the material.

Suggested Drying Conditions:

Drying Parameters Typical Parameters
Drying Temperature 80íŠ
Drying Time 3-4h (before opening);5-6h (after opening)
Air Dew Point Temperature not higher than -40íŠ

Remarks: In the injection molding process, in order to prevent the material from absorbing moisture during the processing, the color can be matched according to the actual weight. If the actual weight is small, it is recommended that the 25kg/bag of materials should be matched with 2-3 times of color matching frequency.

3. Material Processing
Heat-resistant resin can be processed on a traditional injection molding machine. After the material is dried at 80íŠ for 4 hours, the material is melted at the appropriate temperature of the injection molding machine. The injection molding process is directly related to the melting temperature. It is recommended to comprehensively control the injection temperature, injection back pressure, injection speed, cooling temperature and other parameters.

Middle Section 185-190íŠ
Front Section 190-200íŠ

4. Coloring of Materials
In order to ensure the aesthetics and color uniformity of the product, it is recommended to use a polylactic acid-based masterbatch with good compatibility for mixed injection molding or use toner for mixed injection molding for the color matching of the product.

5. Equipment Cleaning
5.1. PLA material is a kind of material that is prone to thermal degradation. After each injection is completed, high-viscosity PP needs to be used to clean the injection molding machine.
2. If the material is discolored and fluidity becomes larger during the processing, measures should be taken immediately to empty the material in the barrel, clean the screw, reduce the temperature of the material and then melt the glue again. Observe the state of the material melt to see if it returns to normal. If it is normal, continue to produce. If it is abnormal, adjust accordingly.

6. Recycling of Recycled Materials
The recycled materials of this resin can be recycled. The recycled materials can be directly crushed during the production process and mixed with new materials. It is recommended that the use ratio of recycled materials not exceed 10% (recommended) in order not to affect the performance of the product.

Drying Time 3-4h (before opening);5-6h (after opening)
Air Dew Point Temperature not higher than -40íŠ

Remarks: In the injection molding process, in order to prevent the material from absorbing moisture during the processing, the color can be matched according to the weight of the actual object. If the weight of the actual object is small, it will take long timer before injection and so it is recommended that each 25kg/bag could be color matched with the color-matching frequency as 2-3 times.

3. Material Processing
Heat-resistant resin can be processed on a traditional injection molding machine. After the material is dried at 80íŠ for 4 hours, the material is melted at the appropriate temperature of the injection molding machine. The injection molding process has a direct relationship with the melting temperature. It is recommended to comprehensively control the injection temperature, injection back pressure, injection speed, cooling temperature and other parameters. The recommended processing technology is shown in the following table:

Material-Throat Temperature 40íŠ
Melting Temperature 185-195íŠ
Barrel Temperature 180-200íŠ
Back Section 170-180íŠ
Middle Section 185-190íŠ
Front Section 190-200íŠ

4. Coloring of Materials
In order to ensure the beauty of the product and the uniformity of coloring, it is recommended to use a polylactic acid-based color masterbatch with better compatibility for mixed injection molding or use toner for mixed injection molding for the color matching of the product.

5. Equipment Cleaning
5.1. PLA material is a kind of material that is prone to thermal degradation. After each injection is completed, high-viscosity PP needs to be used to clean the injection molding machine
5.2. If the material changes color and fluidity increases during the processing, measures should be taken immediately to empty the material in the barrel to clean the screw, lower the temperature of the screw, and then melt the material again. Observe the state of the material melt to see if it returns to normal. If it is normal, continue to produce. If it is abnormal, adjust accordingly.

6. Recycling of Recycled Materials
The recycled materials of this resin can be recycled. The recycled materials can be directly crushed during the production process and mixed with new materials. It is recommended that the use ratio of recycled materials don't exceed 10% (recommended) in order not to affect the performance of the product.
