Sponge Neoprene vs Other Rubber Types - Comparison Guide
Sponge Neoprene vs EPDM Rubber: Neoprene offers superior oil resistance and better cushioning properties. EPDM has better weather resistance. Choose neoprene for applications requiring oil resistance and shock absorption.
Sponge Neoprene vs SBR Rubber: Neoprene provides better chemical resistance, oil resistance, and temperature range. SBR is more economical for general-purpose applications. Neoprene is premium choice for demanding environments.
Sponge Neoprene vs Solid Neoprene: Sponge neoprene offers superior cushioning, thermal insulation, and sealing conformability. Solid neoprene provides higher tensile strength. Choose sponge for cushioning and insulation applications.
Sponge Neoprene vs Nitrile: Both offer excellent oil resistance. Neoprene has better weather resistance and wider temperature range. Nitrile has superior fuel resistance. Neoprene is more versatile for general industrial use.
Temperature & Environment Performance
Our sponge neoprene rubber sheet excels across extreme conditions:
- Cold Temperature Performance: Maintains flexibility down to -40°C - perfect for cold storage seals, refrigeration applications, and arctic environments
- High Temperature Performance: Stable up to +100°C - ideal for automotive under-hood applications, hot water systems, and industrial heat exposure
- Extreme Temperature Range: The -40°C to +100°C range makes sponge neoprene suitable for applications with dramatic temperature fluctuations
- Outdoor Durability: UV and ozone resistance ensures long-term performance in outdoor marine and automotive applications

Frequently Asked Questions
What is sponge neoprene rubber and what is it used for?
Sponge neoprene is closed-cell foam neoprene rubber offering superior cushioning, shock absorption, and thermal insulation. It's used for vibration isolation pads, weatherstripping, HVAC insulation, marine seals, automotive applications, and protective padding where cushioning and sealing are required.
What thickness sponge neoprene for vibration isolation?
For vibration isolation, 5-6mm thickness works well for moderate machinery. For heavy equipment or maximum isolation, use 10-15mm thickness. The thicker the material, the greater the vibration dampening capability.
Is sponge neoprene oil resistant?
Yes, sponge neoprene has excellent oil resistance - far superior to EPDM and SBR rubber. It resists petroleum oils, fuels, hydraulic fluids, and most industrial oils, making it ideal for automotive and industrial applications with oil exposure.
Can sponge neoprene be used outdoors?
Yes, sponge neoprene has good UV resistance and excellent ozone resistance, making it suitable for outdoor applications including marine environments, automotive weatherstripping, and outdoor equipment seals. It performs better outdoors than SBR rubber.
What is the difference between sponge neoprene and solid neoprene?
Sponge neoprene has a closed-cell foam structure providing superior cushioning, thermal insulation, and sealing conformability. Solid neoprene is denser with higher tensile strength. Choose sponge for cushioning/insulation, solid for structural strength.
How do I cut sponge neoprene rubber sheet?
Use sharp scissors or a utility knife with a fresh blade. Sponge neoprene cuts easily due to its foam structure. For precision cuts, use a straight edge. A band saw or rotary cutter works well for production cutting. The material compresses easily, so use light pressure.
Is sponge neoprene suitable for HVAC applications?
Absolutely! Sponge neoprene is excellent for HVAC applications due to its thermal insulation properties, sealing capability, and resistance to temperature extremes. It's commonly used for duct sealing, pipe insulation, and air handling unit gaskets.
What is the Shore A hardness of sponge neoprene?
Sponge neoprene typically has 40-50 Shore A hardness - softer and more compressible than solid rubber (60-68 Shore A). This soft-medium hardness provides excellent cushioning and sealing conformability while maintaining structural integrity.
Can sponge neoprene be used for soundproofing?
Yes, sponge neoprene provides good sound insulation and acoustic dampening properties. The closed-cell structure absorbs sound vibrations, making it effective for studio soundproofing, noise reduction barriers, and vibration dampening in automotive and industrial applications.
