ZR—250B

Time:2016-9-23 17:15:11  Hits:

ZR—250B  It is mainly used for manufacture of polypropylene (PP) fiber product, such as all kinds of cement bulk bag, chemical bag, pharmaceutical cleanness bag, breathable bag, leak proof bag and so on. Its adding content is 8% to 20%. Thetensile strength, flexural strength and the smooth of the fiber product can be significantly improved and the cost of product can also be decreased.
