Two new low-smoke, zero halogen, flame retardant TPEs from Polymax Elastomer Technology are designed as an environmentally friendly and safe alternative to PVC or halogenated flame retardant TPE for wire and cable jacketing applications.

Available through Alliance Polymers & Services, Maxelast FH7990U and Maxelast FH7990V meet UL 62/1581 VW-1 or VDE H03Z1Z1/HO5Z1Z1 specifications, respectively, and are offered in Shore A hardness grades of 87 or 85.

Unlike PVC, the Maxelast TPE formulations are safe: they’re non-hazardous to the environment, can be recycled, and during burn tests emit no hazardous gases and have low smoke.

Also, the two new TPEs resist cracking at temperatures up to 1508C/3028F, have superior resistance to aging and good melt strength to deliver rugged jackets for wire and cable with a smooth surface.
