TPUs are a class of Thermoplastic Elastomers that are composed of a Polyurethane (PU) polymer matrix and a dispersed elastomeric phase. TPUs can be formulated to exhibit a wide range of properties, including high strength, high elasticity, and high abrasion resistance. They are often used in applications such as footwear, sports equipment, and industrial hoses.
TPVs are a blend of a thermoplastic matrix, such as PP or polyethylene (PE), and a cross-linked elastomeric phase, such as EPDM. TPVs exhibit excellent flexibility, low-temperature impact resistance, and resistance to weathering and chemicals. They are commonly used in automotive applications, such as seals, gaskets, and weatherstripping.
The properties of Thermoplastic Elastomers can be tailored to meet specific application requirements by adjusting the composition and structure of the material. For example, the ratio of the elastomeric phase to the thermoplastic matrix can be varied to control the elasticity and strength of the material. Additionally, the molecular weight and structure of the polymer chains within the TPE can be adjusted to control the melt flow properties of the material, which affects its processability during manufacturing.
