Resistant to hydrolysis PPO GFN2, with a 20% glass fiber reinforced base and low water absorption rate

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: PPE+PS blend. 20% glass fiber reinforcement. Compliant with FDA (with restrictions). Low water absorption rate. Hydrolytic stability. Dimensional stability.

　　Purpose: Suitable for fluid engineering applications, including pump casings and impellers, valve components, etc. Large and small household appliances; Electronic communication plastic parts and accessories; Electric tool; Automotive internal components
