About glass fiber reinforced polyurethane profiles:
1. Mechanical properties and fire resistance of glass fiber reinforced polyurethane pultruded profiles
The fire resistance of glass fiber reinforced polyurethane profiles comes from the material itself. Glass fiber is an inorganic fiber with good flame retardancy and heat resistance, and its melting point is usually above 1000 degrees. However, polyurethane is a thermosetting material, which will form a carbonized layer on the surface after encountering fire to prevent the flame from penetrating, and will not melt or produce droplets. The glass fiber reinforced polyurethane composite is difficult to burn in case of fire, and the high temperature on the fire face is also difficult to transmit to the other side.
2. Technological advantages of glass fiber reinforced polyurethane
1) High fiber content, simple fiber structure, superior profile performance:

The fiber content can reach 80%, greatly improving the performance of the profile.
The utility model reduces or even omits the use of fiber felt or cloth, greatly simplifies the production and improves the efficiency.
It can produce complex section and thin-walled profiles without cracking.
The profile surface is smooth.
2) Stable and reliable material performance and quality:
The proportion of raw materials is fixed. All raw materials are used after testing to ensure product quality.
Automated production. All processes such as raw material proportioning, mixing, conveying, fiber soaking, traction, profile curing and forming, cutting, etc. are completed by automatic control equipment to ensure the consistency of product quality.
3) Clean and environment-friendly production:
The polyurethane resin contains no styrene, which minimizes the impact on the environment and workers' health.
3. Surface decoration of glass fiber reinforced polyurethane profiles
The fiber content of glass fiber reinforced polyurethane material is high. In order to meet the requirements of protection and beauty, appropriate paint system can be selected to paint the surface. The new generation waterborne environment-friendly polyurethane coating developed by Deyilong's partners is specially used for the decoration and protection of the surface of glass fiber reinforced polyurethane profiles. It has the following characteristics:
The specific system can effectively and evenly cover and improve the surface flatness of glass fiber reinforced polyurethane materials
The surface of glass fiber reinforced polyurethane material has excellent adhesion
Durable protection, light/ultraviolet resistance, anti-aging
Flexible choice of color, luster and surface effect to meet diversified needs
