Extrusion-Grade Supply • One-Stop Support
Thermoplastic Elastomer Compounds (TPE) – Extrusion Grade Pellets
Need a stable TPE compound for extrusion? Jinxin supplies formulated thermoplastic elastomer pellets for elastic extrusion products—especially sheet/strip and band extrusion, including transparent projects.
One-stop extrusion support: equipment + proven compound recommendation, coordinated by one team.
What a “TPE Compound” Means & Where We Fit
On this page, “TPE compound” refers to formulated thermoplastic elastomer delivered in pellet form, ready to feed into a single-screw extruder.
Our Validated Scope:
- Standardized for Bands: For sheet/strip and elastic bands, we use proven formulations ready for immediate production.
- Custom for Profiles: For tubing and complex profiles, geometry and tooling vary. We recommend a case-by-case evaluation or small trial to ensure precise dimensions.
Why One-Stop Matters for Elastic Extrusion Products
The Formulation Challenge
In SEBS-based TPE compounds, performance is driven by a delicate formulation balance—polymer backbone, oil loading, and filler package.
- Too much filler (e.g., CaCO₃) can raise hardness and reduce stretch, making the product feel “dead” or brittle.
- Insufficient oil reduces elasticity, while excessive oil creates surface tack and migration risks.
The “Hidden Cost” of Generic Material
If a sample feels unusually hard with limited elongation, it is often a sign of a cost-driven formulation where elasticity and snap-back recovery are sacrificed. This leads to production headaches: surging, die swell instability, and products that fail tension tests.
The Jinxin Advantage
By aligning machine setup with a proven compound, we help you reduce unnecessary trial-and-error during startup.
We focus on extrusion-grade formulations that maintain a workable balance for elastic products—ensuring the right elastic recovery and surface feel (matte/dry) straight out of the die.
- Less Debugging: Start with parameters that match the material.
- Unified Support: Don’t troubleshoot between two suppliers.
This is why we match the grade to your specific feel and recovery target, not just a Shore hardness number.
Validated Extrusion Applications (Current Focus)
Band & Sheet Grade
(Proven in Repeat Production)
Typical Products:
Tourniquet-style bands, Esmark-style bands, Resistance/Yoga bands.
What We Match:
Target feel and recovery behavior (Snap-back).
Surface requirement (Dry-touch vs. Tacky).
Shore A hardness target.
Tubing & Profiles
(Project-Based Evaluation)
Typical Products:
Flexible tubing, sealing strips, soft profiles.
Evaluation Service:
Profile extrusion depends heavily on die swell and cooling. We evaluate suitability based on your:
Cross-section drawing & Wall thickness.
Tooling design & Cooling method.
