neoprenebased

Neoprene-based materials are those in which neoprene, or polychloroprene, serves as the primary polymer matrix. Neoprene is a family of synthetic rubbers first developed in the 1930s by DuPont and is now produced by several manufacturers. Neoprene-based elastomers are valued for a combination of elasticity, chemical resistance, and stability across a wide temperature range.

Key properties include good resilience and flexibility across a wide temperature range, resistance to oils and many solvents, and water and ozone resistance. Neoprene can be used as solid elastomer or as foam for cushioning and insulation, and it can be reinforced with fabric or blended with other polymers to tailor hardness and performance.

Production and formulation: Neoprene is produced by polymerizing chloroprene to polychloroprene. Commercial neoprene materials are compounded with additives such as fillers, plasticizers, pigments, and vulcanizing systems to achieve desired properties. They can be processed by extrusion, molding, calendering, or foaming, and in some products serve as a matrix with reinforcing fabrics.

Applications: The best-known neoprene-based products include wetsuits, drysuits, gloves, and protective padding; industrial uses include seals and gaskets, hoses, electrical insulation, and sporting goods. Neoprene foams are used for acoustic and thermal insulation as well.

Environmental and lifecycle notes: Neoprene is synthetic and not readily biodegradable. End-of-life options include energy recovery and specialized recycling or reclamation programs; disposal typically follows local regulations for elastomeric materials.
