Environmental Protection Function of Polyurethane

Doors and windows are the weak link in the thermal insulation of the building envelope. The energy lost through the exterior windows of the house is very serious, which is the main reason for affecting the thermal environment of the building and causing excessive energy consumption. Vigorously developing energy-saving doors and windows provides a way to reduce building energy consumption.

In the context of global emission reduction, countries around the world are increasing energy-saving requirements for doors and windows. With existing technology, on the premise of ensuring comprehensive performance, the characteristics of broken bridge aluminum and PVC materials determine their application in door and window profiles. limitations, it is very difficult to improve energy-saving performance. Under this circumstance, glass fiber reinforced polyurethane composite materials began to come into people's field of vision.

Polyurethane pultruded composite materials are high-strength engineering composite materials produced through pultrusion process from 20% high-performance patented polyurethane resin and 80% glass fiber.

Polyurethane is a high-density, polymer material with high strength, toughness, and low temperature resistance. The material is environmentally friendly and non-volatile. Products produced with glass fiber through pultrusion, molding, injection molding and other processes have the characteristics of corrosion resistance, high bending strength, wear resistance, aging resistance, non-thermal conductivity, non-volatility, etc., and have certain Fire resistance, it is widely used in aerospace, petrochemical industry, construction, high-speed rail and subway, bridges and other fields.

In the application of doors and windows, glass fiber reinforced polyurethane profiles have obvious advantages over broken bridge aluminum alloys and plastic steel. The doors and windows made have excellent performance in thermal insulation, wind pressure resistance, air tightness, water tightness, sound insulation, It has advantages in various properties such as fire protection and corrosion resistance. At the same time, the surface of the profile can be subjected to various coating treatments with rich effects.
