Material detail – Neoprene

Neoprene or polychloroprene is a family of synthetic rubbers that are produced by the polymerisation of chloroprene. Exhibiting good chemical stability and flexibility throughout a wide temperature range, and available in either solid rubber or latex form, neoprene is used in a variety of applications including electrical insulation, as an elastomeric membrane, as a flexible waterproof casing or in belt, strap flashing and sleeve form. Neoprene can also be applied directly in liquid form to create a coating for products that need to endure a more demanding environment¹.

Neoprene has qualities that set it apart from other natural and synthetic rubbers, it is more resistant to degradation than many other rubber types and when used as a coating can protect surfaces from corrosion, as such it forms an excellent basis for products such as gaskets, hoses and adhesives, as well as soundproofing or as insulation for metal products in a high voltage environment².

Neoprene can be very effective when used as a foam, both in open-cell and closed-cell form, it can be used as waterproofing and also as a breathable substance.

Neoprene has a very high burn-point, unlike many exclusively hydrocarbon based rubbers, it’s highest burn-point being around 260°C (500°F)³

Neoprene does possess some drawbacks, degradation can occur if it comes into contact with certain chemicals, including hydrochloride acid, acetone, xylene, hydrogen peroxide and chlorine.
