SILTEM™ resin is an amber, transparent, siloxane polyetherimide block copolymer, offering a tailorable combination of strength, flexibility and heat resistance. It may be an option for high performance wire coating solutions meeting high industry and regulatory standards:
- Non fluorinated
- Flexibility - no cracking
- Abrasion resistance
- High heat performance
- Potential Benefits of SILTEM™ Resin
- Non-fluorinated, PFAS-free
- Compliant with flame, smoke and toxicity regulations (FAR 25.853)
- Compliant with certain transportation and infrastructure regulations
- Process and cost efficiency (vs fluoropolymers)
- Ease of processing
- Low corrosiveness, improved cost of ownership
- Low density, lower weight parts
- Durable in a range of harsh environments
- Durability with high service temperatures
- UV stable
- Excellent chemical resistance
- Highly durable in high-radiation environments
- Non-fluorinated, PFAS-free
- SILTEM™ Resin Material Properties
SILTEM™ resin is an amorphous polyetherimidesiloxane (PEI-Si) copolymer that is easily extrudable. The combination of silicone elastomer (Si) with ULTEM™ resin (PEI) provides flexibility with high heat performance.
- Lower Heat
- Higher Flexibility
- Radiation resistance
- Chemical resistance
- UV resistance
- Product 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.
