I believe we all know that TPR material is a kind of thermoplastic soft rubber compound with rubber elasticity and no vulcanization, which can be directly processed and molded (such as injection molding, extrusion, blow molding, etc.), and has the advantages of light weight (low density), environmental protection (non-toxic combustion), long service life (more than 5 10 times compared with traditional rubber), large processing variability, low total cost of products, etc., and can be widely used in major industries. Although TPR materials are widely used, there are many of them whose basic components are not well understood. So do you know what the basic components of TPR materials are? Here's what you know:
The basic components of TPR materials include the following:
1. Thermoplastic elastomers.
Thermoplastic elastomers are one of the main components of TPR materials, which are usually blended with synthetic rubber or thermoplastic elastomers such as styrene-butadiene rubber (SBR), polyurethane (PU), and nitrile rubber (NBR). TPR material's thermoplastic elastomer composition gives it excellent elasticity, flexibility, and resilience, allowing it to maintain stability at low and high temperatures.
2. Filler. Filler is another important component of TPR material, usually using calcium carbonate, talc, carbon black, silica fume and other fillers, which can enhance the hardness, strength and wear resistance of TPR material. The addition of fillers can also make TPR materials more economical, as fillers are generally less expensive than thermoplastic elastomers.
3. Plasticizer.
Plasticizers can be used to adjust the hardness, toughness and flexibility of TPR materials, and liquid hydrocarbons, esters, anhydrides and other substances are usually used as plasticizers.
To sum up, we can see that the basic components of TPR materials include thermoplastic elastomers, fillers, plasticizers, etc. Of course, different TPR materials and formulations may have different chemical compositions and additive types, and the specific ingredients and formulations need to be determined according to the specific materials and application scenarios.
