Polyurethane elastomers are a group of the polyurethanes used in the form of solid layers. In view of the fact that arise from a combination of multiple component can be programmed in advance characteristics, which will be characterized by the resulting material. According to given by the customer physico-chemical properties and strength can find the right material polyurethane and additives.
Properties of the basic polyurethane system are presented below. The offer is also available with enhanced systems and special parameters.
Polyurethane systems:
» water-resistant » oil resistant » Increased strength at low temperatures » enhanced strength against dynamic » increased strength of the static forces » a reduced abrasiveness » flame retardant » with improved antistatic » into contact with food
