About Urethane Rubber Sheet (Ti-Prene Sheet)

Rubber-like elastic bodies obtained by the reaction of polyester or polyether with isocyanate are collectively called urethane rubber. Ti-Prene® is a trademark of our urethane rubber.

Features

Mechanical Strength： Due to its chemical structure, it has a strong secondary bond between molecules, so it has the highest strength among elastic bodies, and because of its high modulus, it is to be less deformed and can withstand heavy loads even with small objects. Due to its high hardness and high elongation, it is to be less susceptible to damage due to impact.
Abrasion Resistance： It has more than 10 times more abrasion resistance than natural rubber. It is to be superior to metal in some conditions of use.
Oil Resistance： It has excellent resistance to most oils, including petroleum-based oils. Especially excellent for mineral oil (only for use at room temperature).
Heat Resistance： The using limit temperature is 70 ° C. Avoid using continuously at 70 ° C or more.
Cold Resistance： It has rubber elasticity and mechanical strength even at -25 ° C or less.
Water Resistance： Please avoid using it in a hot and humid environment because it has the property of being easily hydrolyzed.
Ozone Resistance： It is hardly affected by ozone because it does not contain unsaturated parts in its molecular structure.
Weather Resistance： Please be noted that when used outdoors for a long period of time, the effects of water, humidity, light, etc. may cause deterioration of physical properties and discoloration.

Applications

・General packing, gasket material.
・Cushion material.
・Coupling.
・Bush.
・Scraper.
・Base material for rollers.
・Spring, dice.

*It does not meet food hygiene tests.

*Hardness measurement is revised to “After 3 seconds” according to JIS K 6253 (2006). However, generally, the conventional "measurement within 1 second" is to be the mainstream for nominal hardness, so this result is measured value and the measurement result after 3 seconds is shown in ().
