Glass fiber reinforced polyurethane (grpu) energy-saving windows are favored
at the recently concluded 8th China (Shanghai) International Building Energy Conservation and new building materials exhibition, the glass fiber reinforced polyurethane (grpu) energy-saving windows jointly developed by Bayer materials technology and Jiangsu Yuansheng Composite Technology Co., Ltd. were favored by Chinese and foreign merchants. The product has been tested by the national authoritative department. The new Mitsui chemical material plastic looks like a ceramic that changes color when exposed to light. The heat transfer coefficient is as low as 1.1w/(M2 · K), reaching the highest level 9 of the national thermal insulation performance of building exterior doors and windows. It meets all the requirements of wedge-shaped clamps (referring to clamps with inclined locking principle structure), counter clamp clamps (referring to clamps with single-sided or double-sided rib top locking principle structure) in China Winding fixture (refers to the fixture that the sample is locked by winding), eccentric fixture (refers to the fixture that adopts the eccentric locking principle structure), lever fixture (refers to the fixture that adopts the lever force amplification principle structure), shoulder fixture (refers to the fixture that is suitable for the shoulder sample), bolt fixture (refers to the fixture that is suitable for testing the rib strength of bolts, screws, studs, etc.) 90 ° stripping fixture (refers to the requirements for the use of two samples in the vertical climate zone.
