The characteristics of door and window sealing strip
Light bulk density, high expansion and contraction strength, no water absorption (replacement of traditional three oil four felt, asphalt wood fir board and other materials). The product is environmentally friendly, easy to construct, and has good anti-seepage, anti-leakage and water stop effects.
Corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, no deformation, no embrittlement, long service life.
It has an independent open-cell bubble structure. The appearance of the special-made joint board is honeycomb-shaped holes evenly distributed. It can be tightly bonded with cement/sealant without burrs, adapts to changes in natural expansion and contraction, and enhances joint sealing expansion Water stopping effect.
