By adjusting the ratio of soft and hard segments, the hardness of TPEE foam board can be from Shore D30-82, and its elasticity and strength are between rubber and plastic.
Compared with other thermoplastic elastomers (TPE), under low strain conditions, TPEE modulus is higher than other thermoplastic elastomers of the same hardness. When modulus is an important design condition, using TPEE can reduce the cross-sectional area of the product and reduce the amount of material.
TPEE foam board has extremely high tensile strength. Compared with polyurethane (TPU), the compressive modulus and tensile modulus of TPEE are much higher. If the same part is made of TPEE and TPU with the same hardness, the former can withstand greater load.
Above room temperature, TPEE has a high flexural modulus, and is not as hard as TPU at low temperatures, so it is suitable for making cantilever beams or torque-type parts, especially for high-temperature parts.
TPEE has good low temperature flexibility, low temperature notched impact strength is better than other TPEs, and wear resistance is comparable to TPU. Under low strain conditions, TPEE has excellent fatigue resistance and low hysteresis loss. This feature, combined with high elasticity, makes the material an ideal material for multiple cyclic loading conditions, gears, rubber rollers, flexible Both couplings and belts can be used.
