"Thermoplastic Elastomer TPU 1180 A 10 Anti-Yellowing Polyurethane" Details
Thermoplastic elastomer TPU 1180 A 10 anti-yellowing polyurethane
Introduction:
TPU (Thermoplastic polyurethanes) name is thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type. It has a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen-free flame retardant TPU can also replace soft PVC to meet environmental protection requirements in more and more fields. The so-called elastomer refers to a polymer material with glass transition temperature lower than room temperature, elongation at break > 50%, and good recovery after external force is removed. Polyurethane elastomers are a special category of elastomers. Polyurethane elastomers have a wide range of hardness and performance, so polyurethane elastomers are a type of polymer material between rubber and plastic. It can be heated and plasticized, with no or little cross-linking in its chemical structure, and its molecules are basically linear, but there are certain physical cross-linking. This type of polyurethane is called TPU.
The main features of TPU are:
Wide range of hardness: By changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the product still maintains good quality Elasticity and abrasion resistance.
High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.
Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.
Good processing performance: TPU can be processed by common processing methods of thermoplastic materials, such as injection molding, extrusion, calendering, etc. At the same time, the co-processing of TPU and some polymer materials can obtain polymer alloys with complementary properties.
Resistant to oil, water, and mold.
Good recycling.
TPU as an elastomer is a material between rubber and plastic, which can be seen from its rigidity. The rigidity of TPU can be measured by elastic modulus. The elastic modulus of rubber is usually 1~10Mpa, TPU is 10~1000Mpa, and plastic (nylon, ABS, PC, POM) is 1000~10000Mpa. The hardness range of TPU is quite wide, from Shore A 60~Shore D 80 and has high elasticity in the whole hardness range; TPU is flexible in a wide temperature range -40~120℃ without plasticizers; TPU It has good resistance to oils (mineral oils, animal and vegetable oils and lubricating oils) and many solvents; TPU also has good weather resistance and excellent resistance to high-energy rays. It is well known that wear resistance, tear resistance, and flexural strength are excellent; high tensile strength, high elongation, and low long-term compression deformation are all significant advantages of TPU.
