The foamed silicone sealing strip is a kind of sealing strip that uses the characteristics of certain materials to make air holes appear inside it by processing. Divided into EPDM foam sealing strip, silicone foam sealing strip, PU foam sealing strip. The foam sealing strip is formed by microwave vulcanization process at one time, and the surface is smooth and beautiful, without joints. It has good elasticity and compression deformation resistance, and has excellent aging resistance. Excellent flame retardant performance, low smoke and low toxicity; stable product performance and high dimensional accuracy.

 Features:
1. Lightweight, strong and tough
2. Thermal insulation, low thermal conductivity, excellent thermal insulation
3. Non-absorbent with independent bubble structure, very low water absorption
4. Excellent cushioning and impact resistance, can be used as a cushioning material
5. Weather resistance is excellent. EPDM sponge can pass the ozone resistance test (50pphm*40. C*72 hours)

 Product Usage:
1. Packaging materials (buffer materials for transportation of precision machinery, medical equipment, furniture, glass, etc., protective buffer materials for small electrical appliances, etc.)
2. Civil engineering and construction (large slab caulking materials for residential use, door and window sealing materials for residential use, lining materials for anti-shrinking concrete, caulking materials for open channels and waterways, various caulking materials for civil engineering and construction, etc.)
3. Vehicles and ships (door sealing materials, luggage compartment sealing materials, engine hood buffer pads, various pipeline sealing materials, lighting joint materials, engine shock-proof materials, buffer and sealing materials for instruments, etc.)
4. Heat insulation and heat preservation (heat insulation sealing materials for coolers and air conditioners, insulation sealing materials for refrigerators and freezers, etc.)
5. Sound insulation and moisture resistance (anti-noise sealing materials for various mechanical equipment, residential sound insulation wall sealing materials, waterproof and moisture-proof sealing materials for various electrical appliances, moisture-proof sealing materials for various mechanical equipment, etc.).

Silicone rubber is a new type of polymer elastic material with excellent high temperature resistance (250-300℃) and low temperature resistance (-40-60℃), good physiological stability, and can withstand repeated harsh And disinfection conditions, with excellent resilience and small permanent deformation (200 ℃ 48 hours not more than 50%), breakdown voltage (20-25KV/mm), ozone resistance, UV resistance. The sealing strip made of silicone rubber is soft and elastic, non-toxic and odorless after special processing, and can withstand high temperature, high pressure and multiple cooking at 200°C. It is used for thermal insulation of electrical products, internal conduits of drinking water systems, internal connections of industrial refrigeration equipment, gas appliances, and sealing of machinery, lamps and other products.

The characteristics of the silicone foam sealing strip are as follows:
1. The surface can be divided into smooth and textured
2. AOTEMAKE hardness 8-25A
3. Density 0.25-0.9g/cm3
4. Thickness 0.2-50 MM
5. Tensile strength 3.0-5.5 MPa
6. Temperature range -70-300 degrees
7. Any color
8. Comply with environmental certification
