Foamed silicone is a porous silicone material made through a foaming process. Due to its light weight, softness, and temperature resistance, it is widely used in many fields, especially in sealing, heat insulation, and shock absorption.
1. Features Lightweight: low density, light weight. Soft: good elasticity, can return to its original shape after compression. Temperature resistance: high and low temperature resistance, usually stable between -50°C and 200°C. Chemical corrosion resistance: resistant to corrosion by a variety of chemicals. Insulation: excellent electrical insulation performance. Sound absorption and vibration reduction: porous structure helps absorb sound and vibration.
2. Application Sealing materials: seals for electronics, automobiles and other industries. Thermal insulation materials: heat preservation for buildings and industrial equipment. Shock-absorbing materials: shock-absorbing pads for sports equipment and electronic equipment. Medical field: used to make medical gaskets, orthopedic equipment, etc.
3. Advantages Lightweight: Reduces product weight. Good elasticity: Provides good cushioning and sealing effects. Durable: Resistant to aging and has a long service life.
