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 a compression deformation of less than %, which effectively ensures the long-term sealing of doors and windows. The outer covering film greatly extends the service life of the product. The rich color selection makes the appearance gorgeous and novel. The supporting frame It can fix the installation of the product and effectively prevent the product from shrinking. This utility model has the following features: non-toxic and environmentally friendly, sound insulation and noise reduction, ultra-long service life, thermal insulation and energy saving, ultra-wide environmental use range from ℃ to ℃, and has passed tens of thousands of fatigue tests. The product has excellent physical properties during long-term use. Maintain the sealing performance of doors and windows.
*, Material: outer film inner foam skeleton
*, Color: brown
*, Superior performance:
, Compression deformation test: % compression rate at ℃, continuous compression hours, deformation rate %
, compression force test, under % compression rate, applied force, compression rate
, temperature range test: no significant change in sealing performance from ℃ to ℃
, Thermal conductivity value test: value at ℃.
, Fatigue resistance test: imitate the opening and closing of a window ten thousand times, no obvious change in shape
, Sound insulation test: only windows with middle rubber strips, reducing noise by decibels
/> , windows with middle rubber strips and additional rubber strips, reducing noise by decibels
, outdoor aging resistance test: it is more than 10 years old, and the performance remains intact
