Product Details
Product Description
Neoprene Sponge Sheets are made from premium chloroprene rubber (CR) foam featuring a unique closed-cell micro-cellular structure. Offering an exceptional combination of softness, weather resistance, oil resistance, flame retardancy, and superior shock absorption, they are widely used in automotive, electronics, diving gear, sports protection, gasketing, and thermal/acoustic insulation applications.

Product Advantages
Closed-Cell Waterproofing: Independent bubble structure prevents water absorption and penetration, providing excellent airtightness and watertightness.
Superior Cushioning & Shock Absorption: Soft yet resilient texture efficiently absorbs impact forces and mechanical vibrations.
Weather & Chemical Resistance: Excellent resistance to ozone, UV radiation, and various chemical solvents and oils.
Reliable Flame Retardancy: Features natural self-extinguishing properties for enhanced operational safety.
High Processing Flexibility: Thickness, color, pressure-sensitive adhesive (PSA) backing, and fabric lamination can be fully customized.
FAQ
Q1: What industries commonly use neoprene sponge sheets?
A: They are widely used in sporting goods (wetsuits, protective gear), electronic cushioning pads, automotive interior seals, bag linings, and industrial pipeline insulation.
Q2: Do you support fabric lamination or adhesive backing?
A: Yes. We can laminate fabrics such as nylon, lycra, or polyester onto the foam surface, or apply a strong adhesive backing for easy direct installation.
Q3: What are the standard size specifications?
A: Standard sheet sizes typically include width/length combinations like $1\text{m} \times 2\text{m}$ or $1.2\text{m} \times 2.4\text{m}$, with thicknesses ranging from $1\text{mm}$ to $50\text{mm}$. Die-cutting and CNC custom shapes are also available.
Q4: Is this material suitable for extreme temperatures and outdoor aging?
A: Yes. Neoprene inherently offers exceptional weather aging and ozone resistance, ensuring stable, long-term performance in environments ranging from $-40^\circ\text{C}$ to $+105^\circ\text{C}$.
