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.
