Between the use of MMT layer of water as a blowing agent for rigid polyurethane foam composites improved foaming process. The study found organic montmorillonite greatly improved thermal stability and fire retardant properties of the composite material in which PU / DDA-MMT composite material has the highest mechanical properties, thermal stability and flame retardance. 1, the wear resistance of polyurethane composite board manufacturers, long life supply composite polyurethane panels, the wear resistance is 3 to 5 times the steel sieve, not less than five times the ordinary rubber sieve. 2, the maintenance workload of small, easily damaged polyurethane sieve, long service life, it can greatly reduce the amount of maintenance shutdowns and loss. 3, low total cost, although the same size (area) of the polyurethane sieve than a one-time investment in high stainless steel sieve (approximately 2-fold) composite polyurethane boards, but because life is a stainless steel sieve sieve polyurethane 3-5 times hard polyurethane panels, and repair and replacement of fewer, so the total cost is not high, the economy is also very cost-effective. Fiberglass composite polyurethane panels _ _ Qinghua plastic composite polyurethane panels provided by the Engineering Plastics Co. ShangYinXian Tsinghua. ShangYinXian Qinghua Plastics Co., Ltd.
