    Advantages of TPE Materials

    1. Superior Processability

      • Can be molded via injection molding and other processes without vulcanization, enabling short production cycles. Scrap materials are recyclable.

    2. Diverse Physical Properties

      • Offers elasticity, soft touch, and a wide hardness range. Features fatigue resistance, with some formulations exhibiting good chemical resistance.

    3. Environmental Safety

      • Mostly non-toxic and compliant with environmental standards; some are degradable.

    4. Design Flexibility

      • Easy to color, suitable for secondary processing, and can be co-molded with other plastics.

    5. Good Weather Resistance

      • Typically maintains stable performance between -40°C and 100°C, with some grades suitable for broader temperature ranges.

    6. Lightweight

      • Lower density than rubber and some plastics.

    Disadvantages of TPE Materials

    1. Limited High-Temperature Resistance

      • Common types have a maximum service temperature of ≤100°C and may soften/deform at higher temperatures.

    2. Inadequate Oil Resistance

      • Generic types are prone to swelling when in contact with oils. Improved formulations are costly and still inferior to traditional rubber.

    3. Lower Mechanical Strength

      • Tensile and tear strengths are lower than vulcanized rubber, making it unsuitable for high-strength structural components.

    4. Poor Solvent Resistance

      • Some types are easily dissolved by organic solvents such as aromatic hydrocarbons.

    5. Higher Cost

      • Raw material costs for high-performance grades are high, with some relying on imports.

    6. Moderate Dimensional Stability

      • May undergo slight deformation in high-temperature or high-humidity environments.
