Overview
Hardness 86A TPU (Thermoplastic Polyurethane) is a type of elastomer known for its balanced properties of hardness and flexibility. With a Shore hardness of 86A, it strikes a middle ground between soft and rigid materials, making it suitable for a wide range of applications. TPU is a block copolymer composed of hard and soft segments, which contribute to its unique mechanical properties. This material is favored in industries requiring durability, elasticity, and resistance to wear and tear. TPU 86A is commonly processed using methods such as injection molding, extrusion, and blow molding. Its versatility allows it to be used in both industrial and consumer products. The material's ability to withstand repeated stress and environmental factors makes it a reliable choice for demanding applications.
Physical and Chemical Properties
Hardness 86A TPU exhibits a combination of physical and chemical properties that make it highly desirable for various uses. Its Shore hardness of 86A indicates a moderate flexibility, which is ideal for products that need to bend without breaking. The material has a density of approximately 1.10-1.25 g/cm³, contributing to its lightweight yet durable nature. TPU 86A is resistant to abrasion, oils, and greases, making it suitable for mechanical parts and protective coatings. It also has good resistance to UV radiation and ozone, which enhances its longevity in outdoor applications. The material's melting point ranges from 150-200°C, allowing it to be processed at relatively low temperatures compared to other thermoplastics.
Main Applications
Hardness 86A TPU is widely used in industries that require materials with both flexibility and strength. In the footwear industry, it is used for shoe soles, heels, and other components that need to withstand constant wear. Automotive applications include seals, gaskets, and protective covers, where its resistance to oils and greases is beneficial. Sports equipment manufacturers use TPU 86A for items like protective gear, grips, and flexible parts of equipment. Industrial applications include conveyor belts, hoses, and machinery parts that require durability and elasticity. The material's versatility also extends to consumer goods such as phone cases, watch straps, and other products needing a balance of hardness and flexibility.
Safety and Storage
Handling Hardness 86A TPU is generally safe, but standard precautions should be followed to ensure safety. Avoid inhaling dust generated during processing, and use appropriate ventilation in workspaces. Prolonged skin contact should be minimized, as it may cause irritation in sensitive individuals. Storage conditions are critical to maintaining the material's properties. TPU 86A should be stored in a cool, dry place away from direct sunlight and moisture. Exposure to high humidity or extreme temperatures can degrade the material over time. Proper storage ensures the material remains in optimal condition for processing and use.
B2B Procurement Guide
When procuring Hardness 86A TPU, it is essential to work with reputable suppliers who can provide detailed material data sheets and compliance certificates. These documents ensure the material meets industry standards and specifications. Buyers should also consider the supplier's ability to provide consistent quality and reliable delivery schedules. Price negotiations should take into account the volume of purchase, with larger orders typically qualifying for discounts. It is advisable to request samples for testing before committing to bulk purchases. Additionally, buyers should verify the supplier's adherence to environmental and safety regulations to ensure responsible sourcing.
