SEBS Injection Molding: Properties, Applications and Design Guide
SEBS is specified for injection molded programs when a soft styrenic elastomer is needed for grips and overmolds.

When to specify SEBS
How procurement and design teams use SEBS on injection molded programs.
SEBS is specified for injection molded programs when a soft styrenic elastomer is needed for grips and overmolds. Buyers specify the commercial grade on the PO when known, or describe service temperature, chemical exposure, and mechanical targets so engineering can suggest a candidate resin. Quote with CAD and resin notes on the instant quote platform. NetProto builds one hardened steel tool with no minimum order quantity for production parts. For abrasion-resistant grades, see TPU . For vulcanized seals, see TPV . For soft cushioning parts, see EVA . For flexible tubing and fatigue-resistant straps, see Pebax .

Applications
Where this resin shows up on BOMs
Typical molded parts and what to specify on the purchase order.
| Application | Why this resin | Specify on the PO |
|---|---|---|
| Typical molded parts | Soft styrenic elastomer for grips and overmolds. | SEBS grade or family name on PO |
| Secondary features | Confirm fillers and color on datasheet | Compliance filters as requirements |
| Validation builds | First articles on production steel tool | Volume notes for cavity planning |
| Foot pads, strain-relief boots, and overmolded handles | Soft styrenic elastomer. Bonding depends on the substrate. Confirm on the TDS. | SEBS grade, the bond substrate, and the cosmetic target. |

SEBS injection molding FAQ
When should I choose SEBS?
Start with SEBS when you need a soft styrenic elastomer for grips, seals, and overmolds. Match the grade to temperature and chemical exposure on the TDS.
Does this resin require drying?
Follow the supplier TDS for the exact grade. At NetProto, attach the datasheet when moisture-sensitive fillers are used.
What is the minimum order quantity for molded parts at NetProto?
NetProto has no minimum order quantity on molded parts from your production tool. Upload CAD on the instant quote platform to scope tooling and part pricing for your volume.
How do I quote this resin without a final grade selected?
List the resin family on the RFQ, attach environment and compliance notes, and upload CAD. At NetProto, engineers use DFM review to narrow grades before tooling release.
How fast can tooling start for a SEBS part?
NetProto builds the hardened steel tool in about 10 business days on qualified programs, depending on part size and complexity. Upload CAD on the instant quote platform to start DFM review.
