C9021TF PTFE抗磨 耐化學(xué) 耐水解POM Hostaform 用于滑動組合應(yīng)用 

Hostaform C 9021 TF NATURAL是一種非常堅(jiān)硬、剛性、不含重金屬的POM（聚甲醛）共聚物牌號，用PTFE改性。具有很好的耐化學(xué)性（溶劑、燃料和強(qiáng)堿性）、耐水解性、抗疲勞性、抗蠕變性、耐濕性和抗應(yīng)力開裂性。與縮醛均聚物相比，還具有韌性（高達(dá) -40°C）、良好的熱變形溫度（高達(dá) 100°C）、非常好的滑爽/抗磨性能、良好的回彈性、低吸濕性和更高的熱降解和氧化降解穩(wěn)定性。也顯示出易于著色。它可以通過注塑成型進(jìn)行加工。適用于摩擦系數(shù)極低的滑動組合。

Hostaform C 9021 TF NATURAL is a very hard and rigid, heavy-metal free POM (polyoxymethylene) copolymer grade modified with PTFE. Exhibits outstanding chemical (solvents, fuels & strong alkalis)-, hydrolysis-, fatigue-, creep-, moisture- and stress cracking resistance. Also exhibits toughness (up to -40°C), good heat distortion temperature (up to 100°C), very good slip/ wear properties, excellent resilience, low moisture absorption and higher stability to thermal and oxidative degradation compared to acetal homopolymers. Also shows easy colorization. It can be processed by injection molding. Suitable for sliding combinations with very low coefficient of friction.
