HIGH-TEMPERATURE CHARACTERISTICS OF STAINLESS STEELS

high-temperature service, strength at temperature is related to time at temperature. Allowable Deformation Another factor to consider in designing for high-temperature service is the amount of deformation that can be permitted during the total service life.

Thermoplastic Elastomers TPE, TPR - BPF

5) Thermoplastic copolyesters (TPE-E or COPE or TEEE) are used where increased chemical resistance and heat resistance up to 140degC are needed. They also exhibit good fatigue resistance and tear strength and so are used in automotive appliions such as blow moulded boots and bellows, wire and cable, and industrial hose appliions.

Factors That Affect the Chemical Reaction Rate

26/11/2019· Temperature is a measure of the kinetic energy of a system, so higher temperature implies higher average kinetic energy of molecules and more collisions per unit time. A general rule for most (not all) chemical reactions is that the rate at which the reaction proceeds will approximately double for each 10-degree Celsius increase in temperature.

REACTIONS & ENZYMES

Temperature: Increases in temperature will speed up the rate of nonenzyme mediated reactions, and so temperature increase speeds up enzyme mediated reactions, but only to a point. When heated too much, enzymes (since they are proteins dependent on their shape) become denatured.
