Neoprene rubber’s chemical designation is Chloroprene(CR),this material is one of the best all-purpose elastomers which resistance to aging,UV,ozone,oxidation and many petroleum derivatives are of prime importance,also it have excellent resistance to water,and many chemicals,so Neoprene extrusions widely usded in place of high physical characters required . Types of extrusions include gaskets, seals, "P' & 'e' profiles with hollow bulbs, 'U' channels, steel-core clips-on seals, 'D' sections, solid & sponge cords, squares, rectangles, ribbed sections & hollow teardrops.
