( DPE) announced that it will VitonFreeFlowTZ110 and Z210 process aids polyolefin comprehensive on the market. The release of two new products the company is the original manufacturer for masterbatch in plastic sheet and extrusion manufacturer ZTechnology a strong complement to the patented technology, but also to celebrate the Viton. 50th anniversary of the commercialization of fluoroelastomer. The whole commercialization of Viton fluoroelastomer for the later development of industry has laid a solid foundation. In addition, DPE also features a Hypalon chlorosulfonated polyethylene synthetic rubber, Neoprene polychloroprene rubber (Neoprene) and Vertex seal technology. VitonFreeF1owzll0 processing aids and Z210 and Z210 zll0 compared to the original product, the performance is more excellent. It helps eliminate the phenomenon of melt fracture in blown film,[link widoczny dla zalogowanych], extrusion pressure can be reduced to reduce energy consumption and mechanical wear, and reduce the extruder die dirt. In the mild agitation conditions, the use of linear low density polyethylene (LLDPE) mixed solution containing 2% processing aid masterbatch,[link widoczny dla zalogowanych], with melt index of 3 l of a LLDPE for blown film,[link widoczny dla zalogowanych], at low shear extruded under the conditions. Since 1957, the first to be applied to the aerospace industry after, VitonA as the world's first fluoroelastomer products, has gradually developed into a wide variety of product forms the seal for corrosive fluids, in the automobile industry,[link widoczny dla zalogowanych], chemical industry, petrochemical industry , pharmaceuticals and food processing and construction field are applied. K show in 2007, DPE focuses on fluorine elastomer products, including the latest developments, including the newly developed products meet U.S. FDA standards, but also with the discussion of the fluorine elastomer to the plastic film on the cutting-edge research . Whether storage of clean water or drinking water, their general use of the tank liner and cover are made of flexible geomembrane. In this exhibition, DPE production of Hypalon. Chlorosulfonated polyethylene synthetic rubber continues to demonstrate its application in this regard. For example, Hypalon. Be used in the United States recently delivered Reservoir Lake Forest, California, other applications include automotive,[link widoczny dla zalogowanych], wire and cable, such as inflatable kayaks, and single roof. The exhibition, Neoprene polychloroprene rubber gasket and innovative on-site curing system VertexTM sealing process also exhibits in the ranks of DPE.
