High Quality

Thermoplastic Elastomers (TPE, TPR, TPU, TPV)

TPE Pellets：What is TPE?

Thermoplastic elastomers (TPEs) are a class of advanced materials that combine the elasticity of rubber with the processability of plastics. Unlike traditional thermoset rubbers, TPEs can be repeatedly molded, reshaped, and recycled through heat, making them highly versatile and sustainable for modern manufacturing.

Composition & Structure

TPEs are generally made by blending soft elastomeric phases (such as SBS, SEBS, EPDM, or polyurethane) with thermoplastic base polymers (like PP, PE, PS, or TPU), along with functional additives such as:

Plasticizers & oils for softness and flexibility

Flame retardants, antimicrobial agents, antistatic additives for specific applications

Colorants & fillers for customized appearance and texture

Each type of TPE has a distinct internal structure:

TPR (Thermoplastic Rubber): Based on SBS or SEBS block copolymers blended with PS or polyolefins

TPV (Thermoplastic Vulcanizate): Dynamically vulcanized EPDM rubber finely dispersed in a PP matrix

TPU (Thermoplastic Polyurethane): A copolymer of soft polyether/polyester segments and hard diisocyanate chains

General TPEs: Often refer to blends tailored for general-purpose flexibility and usability

Key Performance Advantages

Environmentally friendly and recyclable

Compliant with RoHS, REACH, and FDA requirements

Customizable in hardness (Shore A 5–90), color, transparency, and surface texture

Optional features: anti-bacterial, flame-retardant, conductive, halogen-free, silicone-like finish

TPE Sheets

What Are TPE Sheets?

TPE sheets are soft, flexible thermoplastic elastomer rolls or flat sheets made through continuous extrusion. They combine the comfortable, rubber-like feel of elastomers with the easy processability of plastics, making them an eco-friendly and versatile solution for various applications.

Composition:

TPE sheets are composed of thermoplastic elastomers (such as SEBS, TPV) blended with base polymers (like PP or PE), along with plasticizers, stabilizers, and optional functional additives such as:

Antibacterial agents

Flame retardants

Antistatic or slip-resistant components

These ingredients are adjusted according to the desired physical properties and end-use requirements.
