Shanghai - successful development of new sealing materials

Shanghai Institute of synthetic resin has recently developed a new multifunctional polyurethane foam sealant, which has passed the inspection of the National Fire Equipment Quality Supervision called the static toughness supervision and testing center

this sealant is a new generation of one component polyurethane foam sealant, which has excellent heat insulation, flame retardancy, low water absorption and bonding elasticity, and has uniform foam cells, large foaming in the early stage and long storage life. Because of its uniform bubble and small shrinkage after solidification, it can be constructed in winter. This sealant is suitable for sealing and plugging, heat preservation and insulation, filling gaps and joints, and fixing and bonding required by a variety of building materials, especially for sealing, waterproof and sound insulation between plastic steel or aluminum alloy doors and windows and walls

after many experiments, this sealant has not only completely achieved the effects of sound insulation and flame retardancy, sealing and plugging, and thermal insulation, but also the general technical conditions of anti-theft safety doors gb17565 (1) 998, and butane and metaethane are used as foaming agents, which has changed the previous process of using freon, and also played a positive role in protecting the atmospheric oxygen layer
