What is the difference between Type 5 and type 8 resin powder？

SG-8 and SG-5 resin production process is basically the same, the production device is exactly the same. The main difference lies in the additive formulation, polymerization reaction temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of polymerization kettle, and the reaction requirements are more stringent, and the requirements for operation, safety, technology and personnel quality are more stringent, and the quality of resin is more difficult to control.

Purpose:

SG5 (K-65, S1000) : pipes, profiles, plates, etc.

SG3 (K-70, S1300) : mostly soft products, hoses, wires and cables, films, footwear, toys, auto parts;

SG7, SG8 (K-60, S800, S700) : pipe fittings, sheets, containers, etc.
