Product Overview:
Our TPE/TPR injection molding grade materials are engineered for excellent flow, fast cycle times, and superior surface finish in injection-molded parts. Designed to replace rubber or PVC in both functional and aesthetic applications, these compounds are ideal for products that require softness, flexibility, and high durability.

They are widely used in consumer electronics, automotive components, medical devices, household goods, and power tools. These grades offer strong mechanical properties, excellent surface appearance, and are customizable in terms of color, texture, and functional additives.

Key Features:

  • Easy Processing: Excellent fluidity allows for clean, flash-free filling in intricate molds, even at low injection pressures.

  • Versatile Hardness & Elasticity: From gel-like softness (Shore A 20) to semi-rigid formulations (Shore A 90), the material can be tuned to your exact needs.

  • Overmolding Performance: Provides strong adhesion to common substrates such as PP, ABS, PC, or PA for dual-shot molding or insert molding.

  • Surface Quality: Produces smooth, soft-touch, or textured finishes with great consistency — ideal for consumer-facing products.

  • Mechanical Strength: Durable under repeated stress, with high tear resistance and elasticity.

  • Environmental & Chemical Resistance: Grades available that resist UV exposure, sweat, oils, mild acids, and alcohol-based disinfectants.

  • Color Customization: Can be easily pigmented to match product branding or safety coding requirements.

  • Eco-Friendly & Compliant: Halogen-free, phthalate-free, RoHS/REACH compliant; food-grade versions are FDA/LFGB approved.

Typical Applications:

  • Soft-touch grips for tools, toothbrushes, razors, and pens

  • Phone and tablet cases

  • Automotive air vent seals, mats, buttons, and knobs

  • Medical device housings and seals

  • Baby products and kitchenware (e.g., pacifiers, bottle parts)

  • Wearables, straps, and protective gear

With its balance of comfort, durability, and processing efficiency, our TPE/TPR injection molding materials help manufacturers reduce cycle times, enhance product quality, and support sustainable material choices.
