Thermoplastic Polyurethane (TPU) Resin for Mobile Phone Cases High Transparent TPU Granules TPU Powder Manufacturer

TPU, short for Thermoplastic Polyurethane, is a remarkable thermoplastic elastomer with a wide array of outstanding properties and a broad range of applications

TPU is a block copolymer formed by the reaction of diisocyanates with polyols. It consists of alternating hard and soft segments. The hard segments provide toughness and physical performance, while the soft segments endow flexibility and elastomeric characteristics.

Properties

• Mechanical Properties5: TPU boasts high strength, with a tensile strength of around 30 - 65 MPa, and can endure large deformations, having an elongation at break of up to 1000%. It also has excellent abrasion resistance, being more than five times more wear - resistant than natural rubber, and exhibits high tear resistance and outstanding flex - resistance, making it ideal for applications requiring high mechanical strength.

• Chemical Resistance5: TPU is highly resistant to oils, greases, and many solvents. It shows good stability in fuel oils and mechanical oils. Additionally, it has good resistance to common chemicals, which increases the service life of products in chemical - contact environments.

• Thermal Properties: TPU can operate effectively within a temperature range from - 40 °C to 120 °C. It maintains good elasticity and mechanical properties at low temperatures and does not deform or melt easily at high temperatures.

• Other Properties4: TPU can be formulated to achieve different levels of transparency. Some TPU materials are highly transparent, and at the same time, they maintain good abrasion resistance. Certain TPU types also have good breathability, with a vapor transmission rate that can be adjusted according to requirements. In addition, TPU has excellent biocompatibility, being non - toxic, non - allergenic, and non - irritating, making it suitable for medical applications.
