mechanical property: hardness 30-80D, its mechanical property, elasticity, tension, tenacity and fatigue durability are much better than CR boot.

thermal properties: its high low temperature resistance is better. TPEE boot can resist lowest temperature -40 ℃, and highest temperature 160 ℃. It is usually applied in those extremely cold and hot region, such as Alaska, Canada and Florida.

chemical resistance: its swelling resistance and anti-penetrability is better. its fuel permeability is between 1/3- 1/300 of NR and NBR. It can effectively avoid the oil-leakage accidents and lower the defective percentage.

weather fastness: TPEE boot performance is stable, can continue to work more than 10 years and keep its strength invariant under the conditions of severe weather, like sleet, spray, ozone. If you dip it in the sea over 9 years, its tension is only reduced by 10%.
