More Information
Summary:The present invention uses the low molecular PVC resin whose degree of polymerization P is 400-560 to ensure the fluidity in the plastic injection course, uses the composite stabilizer system to produce the synergistic effect to raise the thermal stability of PVC and uses ACR class working aids and ABS class shock resistant modifier to improve the machinability and raise the shock resistant strength, thus the properties of said engineering plastics are very close to that of the current common used fire-retardant ABS engineering plastics and is an ideal substituent for it.
