ʻO Topilene ® R200P kahi polypropylene random copolymer (PP-R, natural colored) e hōʻike ana i ka maikaʻi loa o ka hydrostatic pressure resistance a me ka paʻa wela. He kūpono ia no nā paipu wai wela a me ke anu a me nā mea pono a me nā paipu hoʻohui radiator. ʻO ia ka hopena o ka polymerization bimodal i hoʻohui ʻia e HYOSUNG a me ka ʻenehana crystallization me ka ʻenehana hana hana PP kiʻekiʻe.
