Flexibility
A flexible material bends more readily than a rigid one.

SEBS(Styrene-ethylene-butylene-styrene)
A hydrogenated styrenic elastomer used in soft, flexible compounds.
Polymer / material family
THE NAME, EXPLAINED
What is SEBS?
SEBS means Styrene-ethylene-butylene-styrene.
A hydrogenated styrenic elastomer used in soft, flexible compounds.
Worth knowing
SEBS is related to SBS but chemically modified. Tell the team about oils, fillers and any rigid overmoulded substrate.
WHY MANUFACTURERS CHOOSE IT01 02 03
Properties with a practical purpose.
Elastic recovery
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.
Weathering potential
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.
Properties vary with formulation, reinforcement, moisture, processing and service conditions. Use the exact grade data sheet for engineering decisions.
THE NEXT-CYCLE QUESTION
What matters when considering recovery?
A known grade and a clean, separated batch make the recycling enquiry more useful. A route must still be agreed.
SEBS is related to SBS but chemically modified. Tell the team about oils, fillers and any rigid overmoulded substrate.
Poly-Cycle can discuss your material information and collection requirements. Inclusion in this guide does not confirm acceptance, a particular recycling method or that every operation takes place at a Poly-Cycle facility.
How assessment and collection workMake the enquiry easier
- Confirm the identity. Keep the manufacturer, trade grade and polymer marking. For an additive or chemical, include the safety data sheet.
- Describe the batch. Give the weight, colour and form: pellets, parts, sheet, film, fibre or another format.
- Explain what else is present. Declare fillers, coatings, metal inserts, other polymers and previous contact with chemicals or other contaminants.
- Agree the route. Share photographs and your collection postcode before arranging a movement.
FROM THE GUIDE TO YOUR MATERIAL
Have SEBS to discuss?
Send the team your grade details, approximate quantity and photographs. We can discuss the information needed for your particular batch.
