Siltem™ Resin STM1500

Technical Datasheet | Supplied by SABIC
Polyetherimide siloxane. Acts as a flame retardant and impact modifier. It is amorphous, material that combines the high-heat resistance of Ultem PEI resin with the flexibility of silicone elastomers. It promotes non-halogenated flame retardance and offers stable di-electrical constant & dissipation factors. It shows improved dispersion and faster dissolution in epoxy systems and standard solvents. It has transparent brown base color. It has long-term heat resistance, high flexibility, high limited oxygen index (LOI) and strong metal adhesion.
