Silicone Foam Hose Strip
PRODUCT CATEGORIES
Main Features
- High and low temperature resistance -60 ℃ to 200 ℃
- High flame retardancy
- Electrical insulation
- Physiological inertia
Silicone foam strips have excellent resistance to compression and deformation. Compared with traditional carbon-based foaming materials, foam silicone can resist to high and low temperatures (-60~200°C). In addition, the material has excellent aging resistance and weather resistance, and is an ideal material for various types of high-performance sealing, shock absorption, cushioning, sound insulation, protection, and insulation.

The foam silicone has excellent mechanical properties under high temperature (above 200°C) environment, and still has a certain degree of toughness and elasticity. The glass transition temperature (Tg) can be as low as -70 ℃.
In general, the working temperature of foam silicone is -60 ℃ to 200 ℃. It can withstand instantaneous high temperatures of thousands of degrees, so it is often used to make high temperature and heat-resistant coatings, such as in the aviation field.
Compared with polyurethane foam, foam silicone can well meet the requirements of EN45545-2 in terms of flame retardancy. Its foam density is 0.08~0.15g/cm3, and its service life can reach 2~4 times that of polyurethane foam.
In addition, it is also significantly better than polyurethane foam in terms of comfort, foam density and environmental protection, so it is expected to replace traditional polyurethane foam in the aerospace, rail transit, and high-end automotive industries.
Foam silicone has good insulation properties. After burning, the generated silica is still an insulating substance.
In addition, foam silicone is not easy to scorch during arc discharge, because its structure has a small number of carbon atoms, and its reinforcing filler white carbon black is suitable for high-voltage applications.
The surface of the foam silicone is hydrophobic, so the physical properties are reduced in a humid environment and the adhesion is poor, which can play a role in isolation.
And it is environmentally friendly, non-toxic, tasteless, and harmless to human health, which creates its excellent physiological inertia.
