Battery Pack Sealing Gasket Pack Seal Silicone Rubber Gasket OEM ODM Silicone Rubber Gasket EPDM Foam Neoprene Foam
F-TECH-FSR370 is a low-stress silicone foamed silicone material. It has a low density and excellent resistance to compression set. Compared with traditional carbon-based foam materials, the material has excellent high and low-temperature resistance (-55-200 °C), high flame retardant (V-0), extremely low smoke density and smoke toxicity. In addition, the material has excellent ageing and weather resistance, making it ideal for all types of shock absorption, cushioning, support, sound insulation, protection, insulation and fire protection.
Silicone foam is a closed-cell material. Closed-cell means that there are no connections between the individual cells and thus the penetration of moisture into the cell structure of the respective flat gasket is prevented. Among other things, the material is predestined for use as sound and heat insulation
The advantages and material properties of silicone foam at a glance
Silicone foam gaskets are characterised by a number of positive properties, which makes it an excellent sealing and insulating material. In addition to its very good thermal resistance in temperature ranges from -80° to +230° C, the material also has excellent physiological properties in terms of biocompatibility and food safety. The closed-cell sealing material is mostly bacteriologically indifferent, allergy-neutral and fungicidal.
Silicone foam is still:
- Non corrosive
- non-adhesive
- not electrically conductive (excellent insulator)
- Highly elastic with high restoring forces
- Easily deformable
- ozone and ageing resistant
- weather-, moisture- and UV-resistant
- vibration-insulating and heat-insulating
- The sealing material is also characterised by extremely low water absorption.
