Ò»¡¢Physical & chemical properties
1¡¢Mechanical property
TPEE has more modulus than other thermoplastic elastomers with the same hardness.
2¡¢Heat resistance
TPEE has excellent heat resistance; the higher the hardness is, the better the heat resistance is. Weightlessness seldom occurs even if TPEE is continuously heated for 10 hours at 110~140¡æ and short-term temperature is higher when heated for 10 hours at 160¡æ and 180¡æ respectively, so TPEE can adapt to baking finish temperature on auto production line (150~160¡æ). Brittle point of TPEE is lower than -70¡æ; the lower the hardness is, the better the low temperature resistance is. Most TPEE can be used for a long term at -40¡æ. Its working temperature is -70~200¡æ.
3¡¢Chemical resistance
TPEE has extremely good oil resistance, which can resist a great majority of polar liquid chemicals (e.g. acid, alkali, diolamine compounds); the higher its hardness is, the better its chemical resistance is.
4¡¢Weatherability and aging resistance
TPEE has goos chemical stability under many conditions such as water mist, ozone and weathering.
¶þ¡¢Applications
TPEE is mainly applied to fields having requirements for shock absorption, impact resistance, good warping strength, tightness and elasticity, oil resistance and chemical resistance. For example, corrosion-resistant, wear-resistant, low & high temperature-resistant materials for polymer modification, auto parts, low & high temperature-resistant cable trunking, hydraulic hose, shoe material, drive belt, rotational molding tyre, flexible joint, anechoic gear, elevator slide, pipe valves of chemical equipment.
