Manufacturing
Neoprene is produced by forming a raw mass through mechanical kneading and rolling. In a multistage process of compression and extrusion this mass is then vulcanized into compact blocks (approximately 1300mm x 2200mm x 30mm) which, after maturing, are split up into sheets of various thicknesses in accordance with customer requirements. Afterwards, further surface treatment is performed or lamination using knitted fabrics is carried out, depending on the intended purpose.

All of the process segments are subject to specific time, pressure and temperature conditions upon which optimal development of the various quality characteristics of the final product depends. The formation of a homogeneous cell structure without any cavities is crucial.

Neoprene is the trade name for a specific synthetic rubber. The technical name for this material is chlorine butadiene rubber (chloroprene rubber - CR).
