What Is Neoprene Fabric?
Neoprene fabric, also known as polychloroprene, is a synthetic rubber material produced by polymerizing chloroprene. It has a closed-cell foam structure, which contributes to its excellent insulation properties. The foam structure is composed of a matrix of neoprene rubber with gas dispersed in closed cells, creating a lightweight and flexible material.
Properties of Neoprene Fabric
Physical Properties

How is Neoprene Fabric Made?
Neoprene Rubber Production
Neoprene fabric is made from neoprene rubber, a synthetic rubber produced by the free-radical polymerization of chloroprene using potassium persulfate as the initiator. The molecular structure of neoprene gives it high chemical stability, hydrophobicity, toughness, durability, and optimal dielectric properties.
Neoprene Fabric Manufacturing Process
- Foaming: Neoprene rubber is foamed to create a porous structure, which provides insulation and buoyancy properties.
- Lamination: The foamed neoprene rubber is laminated between two layers of fabric, typically spandex or tricot warp knitted fabric, using an adhesive coating. This sandwich structure gives the fabric flexibility, stretch, and abrasion resistance.
- Vulcanization: The laminated fabric undergoes vulcanization, a curing process that crosslinks the neoprene rubber, imparting strength and durability.
