1. Excellent Processing Performance
TPV's most significant advantage lies in its thermoplastic processing characteristics. Unlike traditional rubber-which requires lengthy vulcanization for curing and shaping-TPV can be rapidly formed directly using standard plastics processing equipment, such as injection molding, extrusion, and blow molding. This capability shortens production cycles by over 70%⁶. For instance, when TPV is used to injection-mold automotive weatherstrips, the molding process can be completed simultaneously with the glass encapsulation process, thereby significantly boosting production efficiency⁶. Furthermore, TPV melts exhibit low die swell and excellent flow properties, enabling the precise molding of even complex, irregularly shaped parts while ensuring a high-quality surface finish⁶.
2. Outstanding Environmental Adaptability
TPV demonstrates exceptional performance in terms of weather resistance:
High-Temperature Resistance: Standard EPDM/PP-based TPVs can withstand temperatures of up to 135°C for extended periods, while engineering-grade TPVs-such as those introduced by DuPont-can endure even higher temperatures exceeding 150°C.
Oil and Chemical Resistance: The cross-linked rubber phase structure within TPV provides it with excellent resistance to oils, acids, and alkaline substances³.
Aging Resistance: Brands such as Santoprene™ have been tested to demonstrate that TPV can retain its performance integrity even after more than 10 years of outdoor exposure.
3. Environmental Friendliness and Sustainability
TPV is 100% recyclable; processing scrap can be directly re-fed into the production line, fully complying with increasingly stringent global environmental regulations⁹. In contrast, traditional thermoset rubbers are difficult to recycle and typically require disposal via landfill or incineration. Moreover, TPV production does not require the use of plasticizers or other potentially migratory harmful substances, giving it distinct advantages in applications involving food contact and medical devices⁹.
4. Design Flexibility
TPV offers a wide hardness range (Shore A 30–95) and a rich palette of color options. Through processes such as co-extrusion and two-shot injection molding, it can be firmly bonded with other materials (such as PP, ABS, PA, etc.) to meet diverse design requirements³⁹. For example, automotive fuel lines can be manufactured using a PA/TPV co-extrusion structure, featuring an oil-resistant inner layer and a weather-resistant outer layer; this integrated molding approach simplifies the assembly process⁶.
