What is the difference between TPR and PVC materials?

的优点:软胶PVC弹性良好;耐老化、耐酸碱性优良;并且PVC成本较为低廉;可快速注塑加工成型。 Advantages of PVC : Soft rubber PVC has good elasticity; excellent aging resistance, acid and alkali resistance; and the cost of PVC is relatively low; it can be quickly injection-molded.

Insufficient PVC: Contains toxic halogen element chlorine and has a strong odor; it may contain toxic plasticizers and heavy metals; combustion may release carcinogens dioxins; it is easy to become brittle at low temperatures and has poor elasticity; permanent deformation occurs.

Advantages of TPE / TPR: good elasticity; customizable physical properties and hardness; good combination of two-color injection molding coating; small odor, no toxic plasticizer, heavy metals and other harmful substances, excellent environmental protection performance; good low temperature resistance.

Insufficient TPE / TPR: there is permanent deformation; heat resistance needs to be improved; corrosion resistance and solvent resistance are average.

TPE / TPR replaces PVC reviews: Compared with PVC, TPE / TPR is more environmentally friendly, has better low temperature resistance, and is more suitable for two-color injection molding. But for acid and alkali resistance, PVC seems to be better. And for some hard materials, such as pipe, etc., still belong to the PVC (PPR) market, TPE can not be competent.

For molding processing, most TPE / TPR materials have some shrinkage, fluidity, and molding temperature that are different from PVC. When the molds used to make PVC products were changed to TPE / TPR for processing, the TPE / TPR material compounding system should be appropriately adjusted.

TPE replaces common applications of PVC: wire and cable, sex toys, soft toys (dolls, toy wheels), luggage accessories, handlebars for bicycles and motorcycles, seals, seals, etc.
