SEBS

Styrene ethylene butylene styrene block copolymer

SEBS is the hydrogenated form of SBS: its saturated midblock makes it resistant to UV, ozone and heat, colourless and odourless. It is the base rubber of TPE compounds, blended with oil, filler and PP to the required hardness. It is standard in medical, toy and soft-touch applications.

Overview

SEBS is the standard grade of the SEBS family in the elastomers group. It is used in applications such as tpe-s compounding, medical tubing and disposables, adhesives and sealants. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

Applications

  • TPE-S compounding
  • Medical tubing and disposables
  • Adhesives and sealants
  • PP and PE impact modifier

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for SEBS are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
