MATERIAL
100% closed cell macromolecule elastic foam. They mainly are 100% closed cell EVA foam, according to targeted use. EVA foams are resilient, closed cells to avoid water absorption and are produced either by rolls or blocks. Those elements are glued or thermobounded to constitute monolithic cocon or core, then tooled to requested shape before being encapsulated by tough reinforced SPUA coating matrix as here under.
SUPA High-tech Elastomer
Technical reinforcement cord fabric
They are applied according to building rules of soft composites reinforcement to strengthen the"matrix"and constitute the encapsulating coating for Zhonghaike's fenders, buoys and floats, etc. The main reinforcement fabric in Zhonghaike is 1480dtex/3 chinlon tyre cord, which is widely used in pneumatic fender and tire products.
