With the development of society, the higher the number of people's daily necessities is, the higher the level of hand-feeling, the exquisiteness, etc.; the use of TPE is also becoming more and more widespread. The following is a small series for everyone to briefly introduce TPE plastic bags. PC.ABS material properties:
TPE.TPR encapsulated ABS.PC, refers to the use of secondary injection (first injection of ABS.PC re-injection TPE.TPR or two-color molding), the TPR soft rubber adhesive shot stuck on the surface of ABS products. A good TPE.TPR material formula should ensure that the TPR material has excellent processability and material properties, and the most important thing is to ensure that TPE.TPR and ABS.PC are firmly bonded.
TPE.TPR rubberized ABS.PC material, raw material hardness ShoreA 35~80 degrees, on behalf of the hardness of 60 degrees, TPE.TPR encapsulated ABS.PC material characteristics: excellent fluidity, easy processing and molding, and PC.ABS plastic with good Adhesive, material wear resistance and scratch resistance are good. Appearance of translucent or natural plastic particles, material specific gravity 1.07 ~ 1.25, shrinkage rate of 1.6 ~ 2.0%.
Baking temperature: 80 ~ 100 °C temperature conditions, 2h-4h (through the baking material can improve the surface appearance of the material effect);
Secondary injection processing temperature: temperature 170 ~ 220 °C (general SBS modified TPR processing temperature 170 ~ 190 °C, SEBS modified TPE processing temperature 190 ~ 220 degrees), should be based on product and mold design, actual product condition to do adjustment ;
Practical applications: various types of electronics, household appliances, daily necessities, tool handle products, sports equipment, etc.
Environmental protection features: Halogen-free, non-nonylphenol NP, no plasticizer phthalate and salt, PAHs free from polycyclic aromatic hydrocarbons, and ROHS, REACH, EN71, ASTM F963 detection standards.
