    SBR / Natural Rubber

    Pryže pro všeobecné použitíNatural Rubber is a good gasket material due to excellent physical properties. Natural rubber has superior resilience, tensile, elongation and abrasion resistance, good low temperature flexibility and compression set and excellent adhesion to fabric and metals.

    If required, we supply technical rubbers in the form of semi-finished or finished products. Most of the standard technical rubbers in our range are permanently in stock, so we can offer not only very short delivery or production times, but also the possibility of producing atypical variants from a single piece.

    Delivery times: It mainly depends on the batch size and the complexity of products. Our standard delivery time is usually no more than one week of placing the order. Given our warehouse stock we are able to offer production on short notice in emergency situations.
