TpR and TpE are thermoplastic elastomers, and there is currently no standard definition in the elastomer industry. In a broad sense, TPE and TPR are both general terms for elastomers, with no difference. However, from the narrower perspective of the TPE industry, there are still some differences between TPE and TPR. TPE is the abbreviation of the English name Thermoplastic Elastomer, which means thermoplastic elastomer. TPR is the abbreviation of the English name Thermoplastic rubber, which means thermoplastic rubber. Below, TpR-TpE manufacturers will talk about TPE and TPR materials.

Broadly speaking, TPE and TPR are both general terms for elastomers, with no difference. However, from the narrower perspective of the TPE industry, there are still some differences between TPE and TPR. TPE is an abbreviation for the English name Thermoplastic Elastomer, meaning thermoplastic elastomer. TPR is an abbreviation for the English name Thermoplastic rubber, meaning thermoplastic rubber. Below TPR-TPE material Manufacturers discuss the differences between TPE and TPR materials.
TPE is generally modified SEBS materials, and TPR is generally modified materials. SEBS is a hydrogenated product (so-called hydrogenation refers to the introduction of hydrogen atoms into unsaturated molecules under special reaction conditions to achieve a saturated state). SEBS has a saturated molecular structure and excellent properties in terms of aging resistance, yellowing resistance, heat resistance, and corrosion resistance. The relevant properties of TPE are superior to TPR.
TPR-TPE material manufacturers discuss the appearance differences between TPE and TPR:
The surface of TPE particles is matte or frosted, with light scattering properties, while TPR particles are bright and have light reflection properties, especially transparent materials. TPE feels very smooth, while TPR is sticky, especially at temperatures above 30-40 degrees Celsius.
TPR-TPE material manufacturers share the burning differences between TPE and TPR:
TPE burns with light smoke, while TPR produces denser and blacker smoke (mainly because TPE is considered a hydrogenated product of TPR, with a lower C element content than TPR).
TPR-TPE material manufacturers discuss other characteristics of TPE and TPR:
In products requiring adhesive bonding (such as shoes, crafts, toy dolls, etc.), TPR is generally used, as TPR bonds more firmly with adhesives, therefore TPE material rarely bonds with adhesives. In addition, TPR-TPE material manufacturers believe that TPR is suitable for producing products with bright colors and bright surfaces.
Both TPE and TPR have the plasticity of plastics and the elasticity of rubber. TPR molecules have the unsaturated molecular structure of rubber, so they have stronger rubber feel and elasticity.
