Neoprene is a chloroprene-based synthetic caoutchouc foam. Through the mechanical kneading and rolling of different types of caoutchouc together with additional components, a compound is created which is subsequently vulcanized in a multi-stage compression and extrusion process into a compact block. After an appropriate amount of storage time, it is then cut into layers in the desired thicknesses. The final stage consists of a surface treatment (e.g. stamping) or a covering with various textiles.
Attributes: This foamed material is very elastic and consists of up to 95% closed gas cells which means that it has excellent heat insulation qualities. But beyond that, neoprene is notable for its multiplicity of unique attributes. The most notable are: resistance to weather, ozone, sea water, as well as many chemicals and fungi; it is tear and abrasion proof, has high ductility and impact elasticity, adheres well, has very low gas permeability and is very compatibil with human skin.
Applications: The “S” version of neoprene that Modulor has in stock is of a standard quality which is very ductile but nonetheless hard-wearing. With the standard nylon-polyester jersey coating that we have on offer, this neoprene is the same one used in the production of diving or cold-protection suits, bandages and other protective materials, packaging as well as boot lining. In addition, the fabric-coated neoprene is an especially good material for making protective covers and pouches (e.g. for notebooks or mobile phones) as well as backpacks and other accessories.
The thickness of the material produced at the factory is predicated on the amount of heat insulation desired. Thick neoprene is a better insulator but is not as ductile and has a greater buoyancy (divers must consider this fact!). The uncoated neoprene has closed, smooth caoutchouc surfaces. This version is suitable for use as sealing strips within a neoprene suit.
Treatment: Neoprene can be die-cut or punched and normal cutting can be done with a blade or shears. Gluing of the material should be done with elastic contact adhesives. In the production of neoprene suits the material is also glued edge to edge.
