TPE 2650 LSZH is a natural, olefin-based thermoplastic elastomer (TPE) intended for wire and cable insulation and jacketing applications where flexibility, good physical properties and excellent flame resistance are required. TPE 2650 LSZH has a very low and slow heat release when measured in the cone calorimeter per ASTM E 1354-11b. Smoke k(1/m) measurements are very low when compared to halogen or conventional metal hydrate compounds.

TPE 2650 LSZH contains a novel non-halogen intumescent flame retardant additive package designed to reduce normal flame spread characteristics and achieve a VW-1 flame resistant rating on 18 AWG wires and larger. It also offers good extrusion processing characteristics on either conventional polyethylene or PVC extrusion lines. In addition, TPE 2650 LSZH contains a UV stabilization additive package that provides effective long-term UV weather resistance.

TPE 2650 LSZH is readily pigmented to a variety of colors using standard wire and cable color concentrates designed for thermoplastic or crosslinked polyolefins.

Application
TPE 2650 LSZH is intended for use as a tray cable or riser cable jacket. This product is rated a V-0 by UL Standard 94 at a minimum thickness of 0.062 inches. TPE 2650 LSZH is expected to achieve a VW-1 flame resistance on 18 AWG or larger conductors as per UL Standard 1581.
