・Medium hardness: Shore D28, with excellent deformation recovery force and structural support capacity
・Balanced mechanical properties: high tensile strength and high elongation at break, suitable for components that can withstand repeated stress
・Excellent processing performance: Compatible with injection molding, extrusion and overmolding, smooth demolding and stable dimensions
・Good covering property: It can be firmly bonded with engineering plastics such as PC, PBT and PA, and is suitable for two-color injection molding
02 | Typical application fields: Meeting the demands of multiple industries for flexible engineering plastics
The applicability of TPEE P128DF is reflected in its extensive end market, covering but not limited to the following directions:
・Consumer electronic device coating: such as power cable interfaces, headbands for headphones, and rubber-coated parts for grips, enhancing the user feel and structural strength.
・Automotive wiring harness protection parts: Emphasizing both flexibility and fatigue resistance, suitable for covering cables, snap-on components, and flexible connection sheaths.
・Industrial pipes and films: They perform particularly well in thin-walled parts that require high flexibility and impact resistance.
・Composite structure buffer cushion layer: It can form a composite structure with hard materials such as PA and PC, and be used as shock-absorbing parts in sports equipment and transportation vehicles.
・Tool handles and soft components: Medium hardness provides a good touch, while also offering creep resistance and durability.

04 | Processing advantages: It can easily handle various complex forming requirements
As a TPEE plastic that can be used in injection molding, extrusion and overmolding, P128DF has excellent process compatibility
・High melt index supports efficient molding: suitable for high-speed injection molding or continuous extrusion in large quantities;
・Moderate dimensional shrinkage rate: This enables more precise mold development and more stable formed parts.
・Low moisture absorption rate reduces drying requirements: The ideal processing state can be achieved under conventional drying conditions.
・It has good adhesion with various engineering plastics: suitable for coating PA, ABS, PC, etc., to achieve an integrated structural design.
This excellent processing performance not only reduces the molding cost but also provides designers with greater creative space.
05 | Innovation and Competitive Advantage: The New Generation of tpee plastic Empowering Design Flexibility
Compared with traditional TPR and TPV, TPEE P128DF shows stronger advantages in high-temperature performance, dynamic recovery and electrical performance:
・The high melting point enhances the heat resistance grade and can be used as a coating material for the near-zone components of the automotive engine compartment.
・It has strong dynamic resilience, reducing structural fatigue and cracks.
・The surface is not prone to aging and becoming sticky, making it more suitable for use as a touchable part of consumer goods.
・Low water absorption and easy drying, solving the molding problems such as moisture absorption and cracking of TPU.
This type of upgraded tpee plastic is particularly suitable for replacing some TPU, TPV or EVA materials, which not only meets the strength requirements but also enhances sustainability and service life.
06 | Customer feedback: Flexible and easy to process, stable performance
Feedback from a cable manufacturing customer in Southeast Asia indicates that after using TPEE P128DF for power sheath coating, the surface finish of the product has increased by 25%, and the extrusion line speed has increased by 15% compared with the original material. Another North American sports equipment manufacturer stated that after adopting this material, the deformation rate of the end products decreased and their service life was significantly extended.
