Details of "TPE particles TPR thermoplastic elastomer plastic adding elastomer particles"
How to produce highly transparent TPR materials into highly transparent products, we should pay attention to:
1: Preparation and drying of TPE raw materials
Since any impurities in the TPE material may affect the transparency of the product, attention must be paid during storage, transportation and feeding
Sealed to ensure clean TPE material. Especially the TPE raw material contains moisture, which will cause the raw material to deteriorate after heating,
So be sure to dry. In injection molding, a dry hopper must be used for feeding. It should also be noted that during the drying process, the input air should be filtered,
Dehumidifies so as not to contaminate ingredients.
2: The problem of recycling TPE materials
In order to prevent the deterioration of the upper surface effect, generally use as little release agent as possible during injection molding; 10%, no major
At 20%.
3: Cleaning of barrel, screw and accessories
In order to prevent the contamination of Guofeng Rubber & Plastics TPE raw materials and the existence of old materials or impurities in the depressions of screw and accessories, especially materials with poor thermal stability, the make
The screw cleaner should be used to clean all parts before use and after shutdown, so as not to stick to impurities.
4: Problems that should be paid attention to in the injection molding process (including the requirements of the injection molding machine)
In order to reduce the internal stress and surface quality defects of the highly transparent TPE material, the following aspects should be paid attention to in the injection molding process.
1: Guofeng Rubber & Plastic TPE You should use an injection molding machine with a screw and a separate temperature control nozzle;
2: The injection temperature should be higher if the material does not decompose;
