聚苯硫醚（PPS）改性樹脂 ECOTRAN®
Polyphenylene Sulfide (PPS) Compound Resin ECOTRAN®
SK化學公司生產的PPS樹脂與既有的PPS樹脂不同，採用了創新的生產工藝，是世界上首款無氯PPS。
SK化學公司所生產的PPS樹脂以及改性產品以“ECOTRAN®”苯硫醚（PPS）樹脂是一種結晶性超級工程塑料，具有耐熱、耐化學品以及阻燃等諸多優異特性。SK化學公司所生產的PPS樹脂與既有PPS樹脂相比具有以下特點。
1.無氯
原料中不含有氯素成分，所以為無氯PPS。
2.低雜質
因生產過程中不產生副生成物，所以與既有的PPS不同，不會含有氯化鈉等雜質。
SK chemicals' world first innovative process of PPS resin production, following advantages can be obtained compared to conventional PPS resins;
1. No chlorine components contained.
2. The process does not produce any by-products such as sodium chlorides which comes with conventional PPS resin.
SK chemicals will promote their PPS resin worldwide under the brand name of ECOTRAN® and Teijin will serve all Japanese customers by cooperation both companies resources and technologies.
