PET塑料在包装领域中具有的应用，无论是包装膜、卷材、还是啤酒瓶，都使用PET塑料。但是当这些材料被废弃时，面临着处理的问题。
TECATRON™ GF40
Polyphenylene Sulfide
Ensinger Inc.
40% 玻璃纤维增强材料
产品说明：
TECATRON™ PPS is a high performance thermoplastic that combines good mechanical properties with excellent thermal and chemical resistance properties. There is no known solvent that dissolves TECATRON™ PPS at temperatures below 392°F. Its low ionic impurities make it an excellent choice for applications where high purity is a concern. TECATRON™ GF40 is a glass reinforced material that offers extremely high strength along with excellent chemical resistance properties. TECATRON™ PVX is a bearing grade PPS that is suitable for high load applications.
TECATRON™ PPS's excellent thermal and chemical resistance along with its ionic impurities make an excellent choice for applications requiring low outgassing and high purity. TECATRON™PPS is typically used in the automotive, electrical/ electronic, industrial, mechanical, appliance and semiconductor industries.
