Degradable materials are a class of polymer materials that can be decomposed into harmless substances through microbial action in the natural environment, which is of great significance in alleviating plastic pollution and protecting the environment. Below are details of several common biodegradable materials:
1. PLA (polylactic acid):
Made from renewable plant resources (such as corn starch), it is a biodegradable plastic.
It has good mechanical properties, thermal stability and chemical resistance, and can be made into products through various processes such as injection moulding, extrusion and blow moulding.
Applications include the packaging industry, textile industry, medical field, agricultural field and automotive industry.
2.PBAT (polybutylene terephthalate/adipic acid):
It is a fully biodegradable plastic with the characteristics of PBA and PBT, good mechanical properties and biodegradability.
It is mainly used in supermarket shopping bags, take-away lunch boxes, agricultural land film, etc., with strong market demand.
3. PCL (polycaprolactone):
It is a polymer with excellent biocompatibility and degradability.
PCL is widely used in the medical field due to its greater ductility and excellent biocompatibility.
The development of the degradable plastics industry faces a number of challenges, such as high costs, technological constraints, processing problems and inadequate back-end treatment facilities. However, with technological progress and policy promotion, degradable plastics are expected to be more widely used in the future.
Problems that may be encountered when processing degradable materials such as PLA, PBAT, etc., include:
1. Insufficient toughness and ductility: For example, although PLA has good mechanical properties, its toughness is poor and its crystallization rate is slow, which limits its use in engineering plastics applications.
2. Narrow processing window: Some degradable materials such as PLA have poor thermal stability and narrow processing window, which may lead to difficulties in the processing process.
3. Melt fluidity problem: In the processing of degradable materials such as PBAT and PLA, the melt pressure is too large due to the excessive viscosity of the melt, which is easy to produce mold expansion and precipitation, while affecting the processing fluidity and reducing the production efficiency.
In order to improve the processing lubricity, these problems can be solved by adding processing AIDS, such as: SILIKE SILIMER DP800, SILIKE SILIMER DP800 is a processing aid developed specifically for degradable materials, which can effectively improve the processing flow and surface quality of degradable materials.
SILIKE SILIMER DP800, high performance processing AIDS specially developed for PLA, PCL, PBAT and other degradable materials.
SILIKE SILIMER DP800 is a modified silicone additive with the following typical advantages for degradable materials:
Processing properties:
Improve the compatibility of powder components and substrate, improve the processing flow of parts, and have efficient lubrication performance. It can reduce melt viscosity, reduce extruder torque, extrusion pressure, improve the processing performance of the material, and have good processing lubricity.
Surface properties:
Improve scratch resistance and wear resistance, reduce the surface friction coefficient, can effectively improve the surface feel of the material, with a certain smoothness.
Other properties:
Effectively maintain the comprehensive mechanical properties of the product, without affecting the degradable characteristics of the product.
The significance of degradable materials is to reduce environmental pollution, reduce energy consumption, and provide sustainable solutions. Biodegradable materials can not only reduce the impact of waste plastics on the environment, but also have huge market prospects and potential. Improving the processability and surface quality of degradable materials is a link that can not be ignored.
Are you engaged in the production and manufacture of degradable materials? if the product defects are caused by the processing of materials, it is recommended that you try SILIMER DP800, SILIMER DP800 is suitable for PLA, PCL, PBAT and other degradable materials. It can be widely used to degrade films, straws, 3D printing consumables and other industries.
