Marine Rubber Insulation
Description:
- Since its internal is composed by a lot of free closed air bubbles, it has low density and the rubber material has low heat coefficient so it is excellent in insulation.
- One layer of film formed in the surface, making it separated with the air completely, so the moisture can not go through and no need to equip the moisture-insulation layer, and the dew fall will not occur in the outer wall.
- Soft in touching, good flexibility, high strength, smooth in surface, easy installation.
- The products contain several chemical ingredient for anti-aging, so it excellent in preventing aging. It also has the capabilities to extreme environment such as good cold resistance, hot resistance, anti-drying, anti-moisture etc with the long service life to at least 20 years and without maintenance.
- Difficult in burning, self crush out in fire, match the requirements in fire fighting, which is safe and reliable.
- Wide application temperature range, excellent in low temperature resistance. It will not become hard or crisp under -50℃.
- It doesn’t contain chlorine, which will result in skin hypersensitiveness.
- It has very strong character in bending and extending, so it can bear the tearing and strongly conveying, and will not be damaged under violence.
- Wide application field due to good effect of sound absorption and shock absorption.
