Hytrel® 7246

01 | Compatible with various processing methods, covering a wider range of production scenarios

Hytrel® 7246 can be applied to a variety of thermal processing methods, which significantly improves the flexibility of production:

✅ Литье под давлением: suitable for parts with complex structure and high precision requirements

✅ Экструзионное формование: widely used for hoses, cable jackets, profiles, etc.

✅ Thermoforming: easy to form sheet products

✅ Pouring moulding: supports hollow structure or special shape processing.

02 | Flexibility and strength for a wide range of mechanical requirements

Hytrel® 7246 balances ductility and structural rigidity with the following mechanical advantages:

🔹 High elongation at break: suitable for frequent bending or dynamic loading environments

🔹 Good shear modulus and tensile strength: can be used in load-bearing areas such as supports, sheaths, etc.

🔹 Low-temperature impact resistance: can maintain flexibility in cold environments

🔹 Excellent tear resistance: suitable for damage-resistant scenarios such as pipes and protective structures

03 | Expanding the boundaries of material development by applying to a wide range of product forms

Hytrel® 7246 supports the development of a wide range of product forms, covering a number of grades:

📄 Film grade: for flexible packaging, sealing films, etc.

🧱 Sheet grade: for structural supports, abrasion-resistant spacer boards, etc.

🌀 Profile grade: to meet the needs of customised extruded parts 🔹 Low-temperature impact resistance: maintains flexibility in cold environments Extrusions

🧪 Tubing grade: widely used in air hoses, hydraulic hoses, automotive hoses, etc.

04 | Weather and aging resistance, adaptable to harsh outdoor environments

UV-resistant agents are added to the material to improve its durability in outdoor applications:

☀️ UV-resistant: colour and performance remain stable under sun exposure

🌧️ Waterproofing and moisture absorption: water absorption is well controlled, suitable for humid environments

❄️ Extremely low brittleness: flexibility and non-cracking properties, even at temperatures of up to -90°C Extremely low embrittlement temperature: flexible and shatterproof even below -90°C.

05 | Meeting the environmental and safety requirements of modern manufacturing

Hytrel® 7246 offers good material intrinsic safety in the face of increasingly stringent environmental regulations:

🌱 Low VOC emissions: complies with VDA 277 for interior components

🔌 Отличные электроизоляционные свойства: suitable for electronic components such as wires, cables and connectors.

🔥 UL94 HB flame-retardant certification: basic fire protection requirements are met.

06 | Stable Thermal Performance for Medium to High Temperature Applications

The thermal stability of Hytrel® 7246 allows it to be used in high-temperature components such as engine compartments, motor systems, etc.:

🌡️ Vickers Softening Temperature of up to 205°C

♨️ Heat Deflection Temperature (0.45MPa) of 100°C

11 | Frequently Asked Questions (FAQ)

Q: For which processes is Hytrel® 5526 suitable? Are there any special equipment requirements?
A: Hytrel® 5526 can be used for injection and extrusion moulding, and is suitable for most general-purpose thermoplastic elastomer processing equipment without any additional modifications.

Q: Can this material be used in wire sheathing or bellows production?
A: Absolutely. It has good flexibility, UV resistance and thermal stability, making it ideal for extruded products such as hoses, cable jackets and bellows.

Q: Can it be used for automotive structural parts or snap injection moulded parts?
A: It is applicable. The material has good structural toughness and dimensional stability, and can be used to manufacture automotive injection moulded parts that require repeated snap-fit or long-term stress.

Q: Any suggestions for mould design? Is there a large shrinkage?
A: The shrinkage rate is about 1.6%. It is recommended to compensate for this in the mould design, especially for products with high structural accuracy, paying attention to the gate layout and cavity compensation.
