TPEE, also known as thermoplastic polyester elastomer, is a block copolymer composed of rigid polyester segments and flexible polyether segments. Its hardness can be adjusted based on the ratio of these hard and soft segments, ranging from Shore 30D to 82D, thereby positioning its elasticity and strength between those of rubber and plastics.
TPEE exhibits outstanding heat resistance; generally, the higher its hardness, the better its thermal stability. It is capable of maintaining both its performance characteristics and structural integrity even in high-temperature environments.
Furthermore, TPEE possesses excellent oil resistance, enabling it to withstand most polar liquid chemical media-such as acids, bases, amines, and glycols-at room temperature.
TPEE also demonstrates robust chemical stability across a wide range of environmental conditions, including exposure to water mist, ozone, and outdoor atmospheric aging.
TPEE is widely utilized in applications requiring shock absorption, impact resistance, flexural endurance, sealing capabilities, elasticity, oil and chemical resistance, as well as sufficient mechanical strength. Whether for automotive components, medical devices, or sports equipment, TPEE stands as an ideal material choice.
