WEB EXCLUSIVE: Alliance Polymers and Services (APS), Romulus, Mich., has introduced its first extrusion blow moldable TPV under the Viprene brand. According to APS, the material can be press blow molded, suction blow molded, or 3D sequential coextruded and offers new opportunities for designers and manufacturers to economically produce automotive, aircraft, and other vehicle parts for applications such as hollow boots, bellows, and ducts.
Blow moldable Viprene 1748 TPV reportedly can be substituted for more costly parts made out of silicone or ethylene-acrylic rubber. It has a 90 Shore A hardness and is formulated to remain flexible at temperatures from 40 to 347 F.
