SABIC SILTEM™ Resin STM1700 Polyetherimide (PEI) (Americas)
Categories:	Polymer; Thermoplastic; Polyetherimide (PEI)
Material Notes:	SILTEM™ STM1700 resin is a flexible polyetherimide(PEI)-siloxane copolymer designed for wire and cable applications. It 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 equipment. The material may also have a fit in flexible profiles or injection molded parts. Features: Low Corrosivity,High Tensile Elongation,Flexible,Chemical Resistance,Low Smoke and Toxicity,High Heat Resistance,Good dimensional stability,Flame Retardant,Non-Halogenated Information provided by SABIC
