Hebei Cuishi Rubber and Plastic Products Technology Co., Ltd. has recently developed a new generation of coated sealing strips, which are composed of high resilience (polyurethane) foam, outer covering (polyethylene) film, and an inner (polypropylene) support skeleton. Rebound foam material has ultra-high resilience and has a compression deformation lower than the following, effectively ensuring the long-term sealing of doors and windows. The outer coating greatly extends the service life of the product. The rich color selection makes the appearance gorgeous and novel. The supporting frame is It can effectively prevent the product from shrinking when it is installed and fixed. This utility model is non-toxic, environmentally friendly, soundproof and noise-reducing, has an ultra-long service life, is thermally insulated and energy-saving, has an ultra-wide environmental use range of ℃ to ℃, and has passed tens of thousands of fatigue tests. The excellent physical properties of the product can be maintained during long-term use. Sealing performance of doors and windows. 1. Scope of use door frame/door bottom seal
2. Material outer film/inner foam/skeleton
3. Color brown
4. Superior performance
, compression deformation test Compression rate at ℃ for continuous compression hours, deformation rate
, compression force test, at a compression rate of /, a force of / is applied, compression rate
, temperature range test from ℃ to ℃, the sealing performance is not obvious Changes
, Thermal conductivity test value at ℃/
, Fatigue resistance test simulates the opening and closing of a window ten thousand times, no obvious change in shape
, Sound insulation test only has a middle strip window, reducing noise by decibels
, windows with middle rubber strips and additional rubber strips, reducing noise in decibels
, outdoor aging resistance test has been more than 10 years, and the performance remains intact
5. Product features
, Advanced engineering polyethylene outer film, good paint resistance and migration resistance, attractive appearance.
, Resistant to (ultraviolet sunlight and UV/㎡ no erosion
, Highly elastic open-cell foamed polyurethane material, long-term shape retention and high elasticity. Temperature range ℃ to ℃
