1) light weight, telescopic strength, does not absorb water (instead of the traditional three oil four felt, asphalt, cedar wood panels and other materials). Products environmentally friendly, simple construction, seepage, leakage, security seal labels effect.
2) corrosion resistance, aging resistance, high temperature +80 ℃ ~ -45 ℃ not flowing, no distortion, no embrittlement, long service life.
3) with independent opening bubble structure, a special type of joint appearance of honeycomb panels uniformly distributed pores, hair can not fight with the cement / adhesive sealant tightly integrated, adapt to the natural expansion and contraction of change, enhancing seams security seal labels Sealing expansion sealing effect.
3 vulcanized EPDM rubber seal
In sealing elastic persistence than PVC strips have greatly strengthened, but due to the need of microwave curing line shape, machining high energy consumption, which is usually 20 times more than PVC processing, products can not be recycled, environmental damage, not the national advocacy products. In addition, the proportion of this type of product materials (1.4 and above) with PVC type quite (low vulcanized EPDM seals greater proportion) of the window with PVC strips similar rate, the use of relatively high cost, doors and windows are difficult to accept.
