SILTEM™ Resin STM1600
SABIC's Specialties Business SILTEM™ Resin STM1600 is a high-quality, flexible polyetherimide (PEI)-siloxane copolymer specifically designed for wire and cable applications. It offers a halogen-free flame retardant solution according to VDE 0472, as well as low smoke emission and toxicity. This amber-colored, transparent material can be self-colored and easily processed using conventional equipment. It may also be suitable for flexible profiles or injection-molded parts. This product does not contain PFAS intentionally added during SHPP’s manufacturing process and are not expected to contain unintentional PFAS impurities. Each user is responsible for evaluating the presence of unintentional PFAS impurities.

- HIGHLIGHTS
Fluoropolymers such as ETFE, FEP and PVDF are used in diverse applications due to their durability (heat, chemical, UV resistance) and flexibility. However, many of these products have come under global regulatory pressure due to the use of fluorosurfactants (PFAS) and their negative impact to the environmental footprint. Non-halogenated and PFAS-free SILTEM™ resins provide excellent high-heat performance, processability and durability without using fluorosurfactants. These advanced materials can be considered for potential use in a variety of industries and applications including transportation, aerospace and telecommunication cables/wires.
