What are the soft types of plastic? Common Soft Plastics

Silicone

Silicone is an elastic, highly soft material with excellent waterproof, insulation, high-temperature resistance, low-temperature resistance, oxidation resistance, and corrosion resistance properties. The softness of silicone can vary depending on its hardness, with lower hardness being softer. It is widely used in kitchenware, electronics, and medical devices.

Polyurethane (PU)

Polyurethane is a polymer material that can be synthesized through acid-base catalysis. It has good shock absorption, softness, and light weight. Its softness can be adjusted by adding additives. Polyurethane is extensively used in automotive manufacturing, sports shoe materials, and furniture production.

PVC (Polyvinyl Chloride)

PVC is a common plastic with good durability and softness, which can be enhanced by adding plasticizers. It is mainly used in construction materials, electrical cables, advertising materials, and automotive interiors.

Other Soft Plastics

In addition to silicone, polyurethane, and PVC, there are other relatively soft plastics like TPE (Thermoplastic Elastomers), TPU (Thermoplastic Polyurethane), and EVA (Ethylene-Vinyl Acetate). TPE, for example, is softer than typical plastics and is considered a middle ground between silicone and PVC.

Conclusion

Silicone, polyurethane, and PVC are among the softer plastics commonly found in the market today, each having distinct characteristics and applications. Choosing the right plastic depends on specific usage requirements.
