Thermoplastic elastomer alloys improve molding performance.

Thermoplastic vulcanizate (TPV) extends processing and injection molding capabilities. Compared with styrenic-based thermoplastic elastomers (TPEs), Versalloy XL 9000 TPV features lower compression set values, improving on processing efficiency. Manufactured by Alliance Alloys LLC (Leominster, MA; 978/534-7216), XL 9000 enhances moldability through its elastomeric performance and uniform shrinking behavior. Other characteristics of TPV include color uniformity; Shore A hardness values of 45, 55, and 70; a rubberlike tactile appeal; and processability in styrenic TPE and TPV tooling. The Versalloy line also offers durability and resistance to chemicals, abrasion, high temperatures, and compression.
