C9021GV3/30 14 黑色 30玻珠POM 用于高強度高剛度和高硬度的 

Hostaform C 9021 GV3/30 14 BLACK是一種非常堅硬、堅硬、不含重金屬的POM（聚甲醛）共聚物級，由30%的玻璃球增強。具有良好的耐化學性（溶劑、燃料和強堿）、耐水解性、抗疲勞性、抗蠕變性、耐濕性和抗應力開裂性。與縮醛均聚物相比，還具有韌性（高達-40°C）、良好的熱變形溫度（高達100°C）、非常好的滑爽/磨損性能、出色的回彈性、低吸濕性以及更高的熱降解和氧化降解穩定性。還顯示出易于著色。它可以通過注塑成型進行加工。適用于低翹曲、尺寸穩定的剛度和硬度較高的成型件。

Hostaform C 9021 GV3/30 14 BLACK is a very hard and rigid, heavy-metal free POM (polyoxymethylene) copolymer grade reinforced with 30% glass spheres. 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 low-warpage and dimensionally stable molded parts with higher rigidity and hardness.
