Material family
SBS and SIS block copolymers
Thermoplastic elastomers for compound selection; SBS and SIS are not assumed interchangeable.
Role in the system: Elastomer phase of a thermoplastic compound.
Selection on request
RAW MATERIALS FOR INDUSTRY
Plastics processing
Polymer and additives are selected for the process and part. A family name does not establish approval or grade suitability.
Technical challenges
- Select the polymer and melt flow rate
- Check additive compatibility and processing
- Test the part against an agreed program
What to include in your brief
- Processing method and equipment
- Geometry, mechanical properties and service conditions
- Required documents, restrictions and test methods
