Superior Weather Resistance and Versatile Applications

Engineered for reliability, the sponge rubber sheet demonstrates excellent resistance to weathering, UV rays, and ozone, especially when using EPDM grades. Its flexible, soft, and compressible nature makes it suitable for sealing, gasketing, shock absorption, and anti-slip flooring across multiple industries such as automotive, electrical, and construction.

Easy Customization and Installation

Our sheets are available in various thicknesses (2 mm to 50 mm), widths (900 mm to 1500 mm), lengths, and styles (plain, textured)with custom sizing on request. They are offered in multiple colors to meet aesthetic or functional demands, and can be supplied in rolls, sheets, or cut-to-order formats. The flexible, lightweight nature ensures straightforward installation for most applications.

FAQs of Sponge Rubber Sheet:

Q: How should sponge rubber sheets be stored to maintain their quality?

A: Sponge rubber sheets should be stored in a cool, dry environment, away from direct sunlight and sources of heat or ozone. This preserves their elasticity and mechanical properties, ensuring long-term reliability.

Q: What are the main benefits of using a sponge rubber sheet over solid rubber?

A: The sponge rubber sheet provides enhanced flexibility, compressibility, lower weight, and superior insulation (thermal and electrical) properties compared to solid rubber. It effectively absorbs vibration and shock, making it a preferred choice for sealing, gasketing, and cushioning.

Q: When is it recommended to use EPDM or Nitrile grades of sponge rubber?

A: EPDM grades are ideal when excellent UV, ozone, and weather resistance are required, such as in outdoor environments. Nitrile is best suited for applications needing superior oil and fuel resistance, commonly found in automotive or industrial settings.

Q: Where can sponge rubber sheets be applied in industry?

A: These sheets are widely used across automotive, electrical, HVAC, packaging, construction, and marine industries. Typical applications include gaskets, seals, padding, insulation, anti-slip flooring, and vibration dampening components.

Q: How is the sponge rubber sheet manufactured and customized?

A: Sponge rubber sheets are made by blending natural and/or synthetic rubbers with additives, followed by expansion and vulcanization. They can be cut to any size, style, or shape as per customer requirements, with options for different colors, thicknesses, and finishes.

Q: What is the process for installing and using sponge rubber sheets?

A: Installation is simplethese sheets can be easily cut and fitted into the desired space using basic tools. For sealing or gasketing, they may be adhered with compatible adhesives. Minimal maintenance is required, thanks to their durable and water-resistant properties.
