SILTEM™ Resin STM1500

Sustainable Grade

SILTEM™ STM1500 resin is a flexible polyetherimide(PEI)-siloxane copolymer designed for wire and cable applications. The material is RoHS compliant and offers a halogen free (according VDE 0472) flame retardant solution that also offers low smoke emission and toxicity. It is an amber colored transparent material that can be selfcolored and easily processed on conventional processing equipment. The material may also be used for extrusion of e.g. corrugated pipes and profiles as well as flexible injection molded parts.

ISCC+ certified renewable bio-based solutions are available for this grade via differentiated color nomenclature.
