PP-RCT（聚丙烯-随机结晶温度）是ISO 1043-1：2001中定义的材料分类，用于描述第二代PP-R材料。这种管类PP-RCT最近被纳入EN ISO 15874，这是用于冷热水管道安装的塑料管道系统的全球标准，可提高管道生产商的性能和竞争力。RA7050-GN是一种PP-RCT聚丙烯无规共聚物，具有特殊的结晶度，这种结晶度是由特殊的β成核作用产生的，尤其在高温下，其表现出改善的耐压性。PP-RCT材料（例如RA7050-GN）的设计满足EN ISO 15874标准中所述的PP-RCT管类要求，例如在70°C下5 MPa的使用寿命为50年，而标准PP-R的使用寿命为3.2 MPa材料根据ISO 9080管道压力测试进行测试。

Product Description:

PP-RCT (PolyPropylene-Random Crystallinity Temperature) is a material classification defined in ISO 1043-1:2001 to describe the second-generation class of PP-R materials. This pipe class, PP-RCT, has recently been included in EN ISO 15874, the global standard for plastics piping systems for Hot and Cold Water pipe installations and enable increased performance and competitiveness for pipe producers. 

RA7050-GN is a PP-RCT polypropylene-random-copolymer with a special crystallinity brought about by a special beta-nucleation which exhibits an improved pressure resistance, especially at elevated temperatures. PP-RCT materials such as RA7050-GN are designed to fulfil the PP-RCT pipe class as described in the EN ISO 15874 standard, e.g. 50 years service life at 70°C at 5 MPa, compared to 3.2 MPa for standard PP-R materials when tested according to the ISO 9080 pipe pressure tests. 

RA7050-GN is ready compounded for maximum quality control. The colour of RA7050-GN is green similar to RAL 6024. 

Applications 
In general RA7050-GN is intended to be used in applications for plumbing and heating, such as in-house hot and cold water pipes and fittings, floor and wall heating systems and radiator connections.
