CR sponge rubber sheet

Cellular Sponge Structure

Different from solid CR rubber sheet, our CR sponge rubber sheet features a porous foamed structure. Closed-cell CR sponge has independent sealed bubbles, low water absorption and strong waterproof performance. It compresses tightly against uneven surfaces and rebounds well, ideal for waterproof sealing gaskets. Open-cell CR sponge has interconnected pores, offering superior sound absorption and air permeability, suitable for noise reduction and breathable padding. Both types stay flexible and can be easily die-cut, punched or trimmed into custom shapes for gaskets, pads and strips.

Premium CR Neoprene Material & Core Performance

Made of high-quality chloroprene rubber compound, this CR sponge sheet delivers balanced comprehensive properties. It has good resistance to oil, mild chemicals, ozone and aging. It also features self-extinguishing flame retardant performance, which slows flame spread when exposed to fire. It maintains stable elasticity over a moderate temperature range and has low compression set, retaining reliable sealing performance after repeated compression.

Key Advantages

• Balanced material performance: Good oil, weather, ozone and chemical resistance

• Flame retardant property: Self-extinguishing neoprene sponge for fire safety applications

• Closed / open cell options: Closed cell for waterproof sealing; open cell for sound absorption

• Excellent shock & vibration damping: Effective cushioning for mechanical equipment

• Low compression set: Good rebound after long-time squeezing for durable sealing

• Water resistance: Closed-cell version blocks moisture penetration

• Easy processing: Can be cut, die-cut into custom gaskets, pads and strips; adhesive backing optional

CR Sponge Rubber Sheet | Neoprene CR Sponge Sheet for Shock Absorption & Sealing Meta Description：CR sponge rubber sheet, also known as neoprene foam sponge. Good oil, flame and chemical resistance, flexible shock absorbing material for gaskets, padding, insulation, sheets & rolls with custom die-cut available.

CR Sponge Rubber Sheet, commonly called neoprene sponge sheet, is a foamed cellular rubber material made of Chloroprene Rubber (CR). It comes in closed-cell and open-cell structures, balancing soft cushioning, shock absorption and excellent resistance to oil, flame and chemicals. This versatile sponge sheet is widely used for sealing, vibration damping, padding and insulation in industrial, marine, automotive and electrical applications.

Typical Applications

• Automotive: Door sealing pads, vibration isolation gaskets, interior cushioning

• Marine: Waterproof hatch gaskets, anti-collision padding for boats

• Electrical & cabinetry: Dust-proof and shock-absorbing gaskets for electrical enclosures

• Machinery: Equipment shock pads, anti-vibration mounts, protective padding

• Construction: Expansion joint sealing, noise reduction pads

• Sporting goods and protective equipment padding
