High flow anti-static PPO 731 SABIC based high-temperature resistant food container valve components

Description :

　　1、 Product Introduction

　　Polyoxyxylene is one of the inexpensive high-temperature resistant plastics, but it is difficult to manufacture and its impact and heat resistance will decrease over time. Mixing polyoxymethylene and polystyrene can improve this drawback. In the 1960s, adjusted polyethylene glycol was introduced under the trade name Noryl. The commonly used material in the market is modified polyphenylene oxide (MPPO), also known as MPPE (Modified Polyphenylene Ether).

　　Performance: high fluidity; Antistatic; High temperature resistance; General

　　Usage: Food container valve components, valves
