This tarpaulin has a smooth finish and is suitable for medium flame applications 1. NBR Rubber / NBR rubber (nytrile butadiene rubber) NBR is a synthetic rubber for special uses that is most needed. Its very good nature is resistant to oil. Even in oil, this rubber does not expand. This property is caused by the presence of acrylonitrile in it. 2. Polyurethane is a mixture or isolation result between rubber and plastic so as to obtain a dissolving material that has the advantage of being very friction resistant, resistant to wear, resistant to some mild chemicals, stable in cold and hot temperatures. Chemical of a material or mixture containing nitrogen, carbon dioxide and oxygen, polyurethane is a polymeric material containing various urethane (-NH-CO-O-) compounds formed from the reaction between polyols (alcohols with more than two reactive hydroxyl groups per molecule) with diisocyanate or polymeric isocyanate with the availability of suitable catalysts and additional ingredients.
