Technical Data
产品说明
AH50G20L is an acetal homopolymer compound incorporating 20% glass fiber, with a viscosity suitable for injection molding applications. It is internally lubricated for use of mold release.
Acetal homopolymer is a highly crystalline engineering thermoplastic which exhibits predictable mechanical performance over a wide temperature range and for extended time periods. The addition of glass fiber significantly improves rigidity, especially at higher temperatures, as well as dimensional stability. As with AH50, the base polymer, AH50G20L exhibits excellent resistance to the effects of a broad range of chemicals, oils, greases and solvents, as well as extremely low moisture absorption.
AH50G20L should be considered for applications where the fundamental characteristics of acetal homopolymer are required, but where improved rigidity, particularly at higher temperatures, and dimensional stability are critical.
