Sealing strip combination polyurethane foaming agent features:
1. It has a continuous and dense surface layer and a high-strength honeycomb structure with interconnect wall with the obturation rate up to 95%;
2, waterproof, heat preservation, heat insulation, gas insulation, corrosion and other characteristics.
I. material introduction:
The coated sealing strip does not adhere to the paint, does not contain CFC, has good air tightness, fire resistance for 90 minutes. PU coating film, good sound insulation performance, can improve the sound insulation effect. Good elastic recovery function, still keep the original shape after many years. Eliminate the gap between window sashes and window sashes height difference, the original empty space into a flexible push pressure push position, improve the sealing of window sashes in order to achieve air permeability, no dust, no mosquitoes and corridor odor effect. The product is mainly used for aluminum plastic doors and Windows seal, door side door bottom seal.
