The INOAC C-4205 is a premium closed-cell CR (neoprene) foam sponge engineered for high-performance sealing, shock absorption, and cushioning. With excellent waterproofing, dustproofing, weather resistance, and flame retardancy, this soft yet highly resilient neoprene rubber sponge is ideal for automotive seals, electronic gaskets, HVAC systems, and construction expansion joints. It supports custom adhesive backing (3M/Tesa) and precision die-cutting to meet exact specifications.

• Excellent Waterproof Sealing: The independent closed-cell structure blocks water, moisture, and air penetration for reliable, long-lasting sealing performance.
• Superior Shock Absorption: Highly resilient CR rubber delivers outstanding cushioning, protecting fragile electronics and components from impact and vibration.
• Flame Retardant & Safe: Formulated with self-extinguishing properties to meet strict industrial safety standards.
• Outstanding Weather & Ageing Resistance: Highly resistant to UV, ozone, and extreme temperatures, making it suitable for demanding outdoor environments.
• Great Processability: Easily laminated with double-sided tape (3M/Tesa) and supports precision die-cutting into custom shapes and sizes.

• Automotive Seals: Weatherstripping, soundproofing, and vibration dampening for car doors, windows, trunks, and engine hoods.
• Electronic Gaskets: Dustproof pads, battery cushioning, and screen sealing for smartphones, laptops, and precision instruments.
• HVAC & Industrial Sealing: Sealing for air conditioning ducts, refrigeration equipment, and machinery enclosures.
• Construction Expansion Joints: Filler material for building infrastructure providing moisture barrier and thermal insulation.
