TPE Manufacturing and Custom Parts
A soft-touch thermoplastic used for grips, seals, strain reliefs, and overmolded features.
- Soft touch
- Flexible
- Overmolding compatible
Material overview
Soft-touch interfaces designed around the substrate and user contact.
TPE materials are used for grips, seals, strain reliefs, feet, and soft-touch overmolded zones. The family includes different chemistries and hardness ranges, so a successful part depends on choosing the TPE together with the rigid substrate and end-use environment.
Texture, parting line, flash control, mechanical locking, and compression behavior should be reviewed early. A visually soft surface does not by itself confirm sealing performance or long-term adhesion.
Key properties
Performance characteristics translated into manufacturing decisions.
Flexible sealing
Can form compliant lips and contact zones when compression and material recovery are validated.
Overmold integration
Enables two-material components using compatible adhesion or designed mechanical retention.
Color and texture
Can provide controlled visual and tactile surfaces, subject to resin, mold texture, and process trials.
Suitable processes

Design considerations
Control the features that affect function and process stability.
G 01
Add mechanical interlocks where the interface allows.
G 02
Keep the overmold thickness and flow path consistent.
G 03
Place parting lines away from sealing and high-touch surfaces.
G 04
Define peel, compression, or tactile acceptance tests when function depends on them.
Limitations
Requirements that need engineering review.
- Bonding varies widely between TPE families and substrate grades.
- Soft surfaces can show drag marks, flash, or handling contamination.
- Compression set and recovery must be tested for sealing functions.
- Color and gloss can shift with texture and process conditions.
RFQ checklist
Material details to include in the quotation package.
Clear requirements help engineering, finishing, inspection, and purchasing review the same target.
- 01Select chemistry and hardness with the substrate and service environment.
- 02Ask for supplier adhesion guidance, then verify it on production-representative samples.
- 03State color, texture, odor, skin-contact, or compliance needs only with documented criteria.

FAQ
TPE questions from engineering and sourcing teams.
How is TPE retained on a rigid housing?
Retention may come from compatible material adhesion, mechanical locks, undercuts, through-holes, or a combination. The interface should be designed and tested with the exact material pair.
Can TPE be used as a functional seal?
Potentially, but hardness, compression, geometry, recovery, fluid exposure, and aging must be validated. A soft feel alone does not establish sealing performance.
Can color and texture be matched on TPE?
Color and texture can be developed, but soft materials respond differently to mold texture and lighting. Approved physical samples are the most reliable acceptance reference.
