Cấu trúc sản phẩm
What Is DuPont's Hytrel® 5526
In the industrial design trend that places higher demands on flexibility, durability and processing performance, DuPont's Hytrel® 5526 has emerged as an ideal material that combines the softness of elastomers with the strength of engineering plastics. As a thermoplastic polyester elastomer (TPEE), it not only possesses outstanding mechanical properties, heat resistance and electrical characteristics, but also demonstrates high adaptability in various application fields. Juyuan is now providing genuine Hytrel® 5526 granules on a long-term basis. We welcome global buyers to cooperate and negotiate.
01 | Material structure highlights: A perfect blend of rigidity and flexibility, with balanced performance
Hytrel® 5526 is a block copolymer material based on the structure of polyester soft segments and rigid hard segments. This molecular architecture endows it with excellent comprehensive performance:
・Outstanding tensile strength and elongation at break: The elongation at break is as high as 780%, and the tensile strength at break is 40 MPa, far exceeding that of traditional rubber.
・High impact absorption capacity: The notched impact value of the cantilever beam is 115 kJ/m² at -40°C, and it remains flexible at low temperatures.
・Excellent heat and weather resistance: The continuous service temperature of RTI can reach 50°C, and the maximum Vicat softening temperature can reach 180° C. At the same time, it has UV resistance.
・Excellent electrical insulation performance: Volume resistance 4E+13 Ω·cm, CTI reaches 600V, suitable for scenarios that require long-term electrical isolation.
This makes Hytrel® 5526 the best solution that takes into account both rigid structural support and flexible moving parts.
02 | Strong process adaptability: An ideal choice for thermoplastic processing
Hytrel® 5526 is supplied in pellet form and is primarily processed by injection molding and thermoforming, meeting diverse production needs.
・High flowability is a key feature of this material, with a melt index of 18 g/10 min (220°C, 2.16 kg). This enables rapid mold filling and reduced cycle times during injection molding, making it particularly suitable for complex structures and thin-walled products.
・In thermoforming applications, Hytrel® 5526 pellets exhibit excellent melt uniformity and thermal stability, ensuring a more stable molding process and significantly improving the dimensional accuracy and surface quality of the finished product.
・Excellent dimensional stability, with a controlled biaxial shrinkage of 1.4%, ensures high consistency in the finished product.
・Unnotched impact tests demonstrate "NB" (no break) at both -30°C and 23°C, demonstrating that the material maintains its toughness across temperature ranges.
This means Hytrel® 5526 is suitable for both mass-produced industrial parts and precision injection-molded consumer goods.
03 | Application Scenarios: Cross-border materials for the high-end market
Thanks to its comprehensive performance features, Hytrel® 5526 is widely adopted in multiple industries:
Application Field | Ứng dụng ví dụ |
Automotive | Drive belt covers, ABS wire harness overmolding, air ducts |
Home Appliances & Electronics | Cable sheathing, connectors, motor components |
Sports Equipment | Ski edge protectors, climbing buckles, sports gear parts |
Industrial Pipes | Corrugated hoses, sealing components, shock-absorbing brackets |
In addition, its low odor grade (VDA 270 class 5) and low atomization value (0.1mg) also make it have the application potential of automotive-grade materials.
