GRPP pipe is a kind of glass fiber reinforced polypropylene pipe, which is what we call modified polypropylene pipe. Add FRP, filler, etc. It has high specific gravity and good strength, but it is easy to crack when it encounters external force. In fact, FRPP pipe is made by adding glass fiber into ordinary PP to improve its corrosion resistance and high temperature resistance. GRPP and FRPP are both PP-PP pipe series, and the main raw materials are PP*** polymers, and their properties are basically the same, except that GRPP pipes are easy to crack. TDR Tiandi Ren brand pipes and fittings produced by Yangzhong Tiandiren Plastic Products Co., Ltd. sell well all over the country.
