New DuPont Soft Thermoplastic Elastomer Grades Stand Up Under the Hood
The new offerings include three new grades of DuPont™ ETPV engineering thermoplastic vulcanizate and a new grade of DuPont™ Hytrel® thermoplastic polyester elastomer. All of them can withstand under-the-hood automotive conditions and high-temperature industrial environments. Typical applications include extruded hose and tubing, blow molded air ducts and injection molded seals and body plugs.
New Hytrel® AC801 NC010 is much softer than any other grade of Hytrel® and has improved heat resistance. Its nominal hardness is Shore A 80, and it is rated for 150ºC service, which is about 20ºC higher than most other Hytrel® grades.
New DuPont™ ETPV 95A02HS BK001 and 95A02 NC010 grades provide outstanding processing stability in profile extrusion and in blow molding, of air ducts for example. The two versions are a black heat-stabilized grade (…BK001) rated for 3000 hours at 150ºC and a standard natural grade (…NC010) for less demanding requirements.
Two other recent DuPont™ ETPV additions have hardness values of 70 and 80 Shore A. Earlier grades in the DuPont™ ETPV product line have Shore A values of 60 and 90.
