THERMOPLASTIC RUBBER (TPR)

Thermoplastic Rubber (TPR) is an elastomeric material based on styrenic block copolymers, blended and modified with resins, plasticizing oils and various functional additives. TPR features broad tunable‑performance range. Sophisticated formula design and modification technologies can greatly expand its application scope to satisfy diverse demands ranging from daily consumer goods to industrial components. The following elaborates on the core characteristics and corresponding main applications of various TPR modifications listed below.

Toughening Modification

TPR itself is a high‑performance elastomer. Toughening modification for TPR aims to further improve its flexibility and impact resistance, especially low‑temperature toughness. By optimizing the ratio of base resins, plasticizers and fillers, TPR can achieve higher elongation at break and lower brittleness temperature while retaining its strength. High‑toughness TPR is mainly used in fields with high requirements for elasticity and durability, such as various shock‑absorbing gaskets, bumpers, sealing rings, and sports‑equipment components subject to repeated dynamic stress.

High Impact Resistance

High impact resistance is one of TPR’s intrinsic properties. Its elastomeric nature enables effective absorption and dissipation of impact energy. It delivers outstanding impact performance especially at low temperatures, making it an ideal candidate for various safety‑protection parts. High‑impact modification further enhances its energy‑absorbing capacity by adjusting the molecular weight of base resins and optimizing formulations. Such materials are widely adopted for scenarios exposed to accidental impact, including sports protective gear, protective gloves, cushion pads, energy‑absorbing components for automotive bumpers and various safety‑protection articles.

Food‑Grade Modification

Food‑grade modification refers to a series of comprehensive modifications centered on hygienic safety for food‑contact scenarios. It requires TPR base resins and all additives to comply with FDA, EU and other relevant regulations; all additives shall be non‑toxic, odor‑free and non‑migratory. Modified materials possess high chemical inertness, and will not leach hazardous substances into food or impair food sensory properties (odor and taste). Food‑contact‑grade TPR is mainly applied to products in direct or indirect contact with food, such as tableware handles, grips for kitchen utensils, water‑path components and sealing rings inside water dispensers and coffee machines, baby bottle accessories, nipples, toothbrushes, toys, food packaging and medical devices.
