Neoprene (CR)
Neoprene is polychloroprene (CR), a synthetic rubber with a balanced set of properties: moderate oil resistance, good weather and ozone resistance, flame resistance and toughness. Typical compounds serve from about −40 to 212 °F (−40 to 100 °C) and range from 30 to 90 Shore A. It is used for gaskets, bellows and boots, closed-cell sponge, and fabric-laminated soft goods like sleeves.

When should you use Neoprene?
Strengths
- Good all-round balance of oil, ozone and weather resistance
- Self-extinguishing; flame-resistant grades for transit and building use
- Tough and abrasion resistant
- Closed-cell sponge and fabric laminates for padded and insulated soft goods
- Bonds well to metal and fabric
Watch for
- Less oil resistant than nitrile and less weather resistant than EPDM
- Costs more than EPDM or SBR
- Some grades stiffen and crystallize in prolonged cold
- Swells in aromatic and chlorinated solvents
Typical parts
- Gaskets and weatherstrip
- CV boots and bellows
- Wetsuits, sleeves and protective cases (laminated sponge)
- Vibration mounts and bumpers
- Hose covers and cable jackets
- Laptop and camera sleeves

Neoprene questions
Neoprene vs EPDM?
EPDM has better weather, ozone, water and heat resistance and costs less. Neoprene adds moderate oil resistance, flame resistance and better bonding to fabric and metal. Choose neoprene when a part sees both oil splash and weather; otherwise EPDM.
Is neoprene waterproof?
Solid and closed-cell neoprene do not absorb water, which is why it is used for wetsuits and gaskets. Open-cell sponge and stitched fabric-laminate seams can wick water unless sealed.
What is neoprene sponge?
Closed-cell neoprene sponge is foamed polychloroprene, graded by firmness under ASTM D1056. It seals uneven surfaces at low closing force, insulates, and laminates to nylon or polyester fabric for sleeves and padding.
