2023年5月31日 · PP-RCT是英文缩写，全称是Poly Propylene Random Crystallinity Temperature，也叫耐高温β-晶型 聚丙烯 ，是经过改良的新一代聚丙烯材料，它采用六方晶型取代了PP-R的单斜晶型。

PP-RCT is a newer generation PP-R material with higher long-term strength at elevated temperatures than earlier PP-R 80 and PP-R 100 resins. PP-RCT material has approximately 25% higher stress capability and a 25% higher pressure rating than PP-R pipes for the same wall thickness at a given operating temperature.

PP-R（Polypropylene-random copolymer）为无规共聚聚丙烯，俗称Ⅲ型聚丙烯，由少量乙烯单体和丙烯用无轨共聚的方式聚合而成，它中和了PP-H、PP-B的优势性能，既能承受一定的高温，又改善了低温抗冲击性能，同时拥有更好的抗蠕变性能，成为更加理想的，可广泛应用 ...
