What Is SK TPEE P155D

Against the backdrop of the increasing demands for lightweight, toughness and dimensional stability of plastic components, thermoplastic polyester elastomers (TPEE) have become a reliable choice for many industries. TPEE P155D launched by SK Comprehensive Chemical is an engineering plastic with good mechanical strength, flexibility and process adaptability, suitable for medium and large-scale mass production scenarios of injection molded products.

01 | Material performance overview: Combining rigidity and flexibility, empowering diverse designs

TPEE P155D combines the structural support of polyester with the ductility of rubber-like materials, demonstrating the following key advantages:

  ・Moderate tensile strength and good elongation: It has a certain structural support capacity, with an elongation at break of 380%, and is suitable for repeated deformation in stress concentration areas.

  ・Excellent impact absorption effect: The notched impact strength is close to 50 kJ/m², which can significantly enhance the drop resistance and crack resistance of the finished product during use.

  ・Moderate flexural modulus: approximately 206 MPa, providing sufficient support for the product while retaining necessary flexibility.

  ・Melting temperature up to 221°C: It has stable thermal processing capabilities and is suitable for applications with high requirements for forming temperature.

  ・A melt index of 18 g/10min: It strikes a balance between fluidity and dimensional control, which is conducive to the forming of complex cavities or thin-walled parts.

  ・A hardness D value of 55 indicates that the material has both flexible covering capacity and initial structural load-bearing performance.

02 | Typical application fields

Relying on its balanced mechanical and thermal properties, TPEE P155D is widely applicable to:

  ・Consumer electronic accessories: such as protective cases, key guards, and variable structure brackets, enhance drop resistance and structural stability;

  ・Rubber-coated parts for electric tool housings: They not only provide a certain degree of support rigidity but also take into account the operation feel and impact resistance.

  ・Interior trim strips or guard plates: Suitable for interior parts that require long-term use and are scratch-resistant and heat-resistant.

  ・Sports equipment buffer components: such as the edges of skateboards, protective gear parts, etc., are suitable for stable deformation recovery after multiple impacts.

03 | Analysis of Processing characteristics

TPEE P155D shows good adaptability in injection molding processing and is particularly suitable for automated molding production lines. The following features should be noted:

  -Medium fluidity ensures smooth filling and is conducive to the molding of molds with rich details or complex structures.

  -A high melting point brings good thermal stability and reduces the risk of thermal degradation during the molding process.

  -The water absorption rate is 1.1%. It is recommended to process it after drying to prevent affecting the stability of the product.

  -The shrinkage rate is approximately 1.7% (in the flow direction). Corresponding shrinkage compensation should be reserved according to the specific mold structure to ensure the accuracy of product dimensions.

04 | Summary of Material Advantages

  -It combines mechanical performance and elasticity, meeting the structural and protection requirements of multiple scenarios.

  -Good impact toughness enhances product durability;

  -It has stable thermal performance, a wide processing window and high forming efficiency.

  -The medium water absorption rate is suitable for most indoor and light industrial environments.
