description
Material properties
Closed-cell structure: independent bubble design, with both elasticity and compressibility, and significant cushioning and shock absorption effect.
Wide temperature range: short-term temperature resistance can reach - 40℃ to 105℃, long-term stability at - 30℃ to 80℃, adapting to extreme environments.
Anti-aging: excellent resistance to ozone, UV and oxidation, long outdoor service life.
Adhesion and sealing
High adhesion: acrylic pressure-sensitive adhesive or butyl adhesive formula, peel strength ≥ 5 N/cm, suitable for rough surfaces.
Waterproof and moisture-proof: closed-cell structure prevents water penetration and can be used in humid environments (such as bathrooms, swimming pools).
Chemical stability
Corrosion resistance: acid, alkali, salt and organic solvent resistance, suitable for chemical equipment or coastal areas.
Insulation: non-conductive material, can isolate different metals to prevent electrolytic corrosion.
Processing and environmental protection
Easy to cut: support customized processing such as die-cutting and striping, suitable for complex shapes.
Environmental protection formula: some products meet RoHS standards, halogen-free and formaldehyde-free.
Application areas
Architecture and engineering
Sealing of curtain walls, doors and windows, sound insulation and shock absorption.
Waterproofing of roofs and pipes, sealing of joints (such as RVs and containers).
Buffering and fixing of glass and metal frames.
Automobile manufacturing
Sealing strips for doors and trunks, dust and water resistance.
Hood sound insulation pads, shock absorption and buffering of battery packs.
Sealing and bonding of lights and dashboards.
Electronics and electrical appliances
Sealing of household appliance housings (such as refrigerators and washing machines).
Insulation and shock absorption of circuit boards and sensors.
Shock protection during transportation of precision instruments.
Industrial equipment
Sealing of pipes of air compressors and fans to reduce leakage.
Anti-corrosion linings for chemical storage tanks.
Anti-slip buffering for sports equipment (such as surfboards and snowboards).
Special scenarios
Waterproof sealing of aquariums and swimming pools.
Weather-resistant sealing of ship decks and hatches.
Temporary fixation in high temperature environments (such as oven parts).
