Technically Specified Rubber
Description
Due to its remarkable strength and fatigue life, NR is a versatile material in many engineering applications. NR has good resistance to creep and stress relaxation. It can withstand temperatures of 100°C and sometimes above, and maintains its flexibility at temperatures below -60°C if compounded for that purpose. The disadvantage of NR is its poor resistance to oil and environmental damage (oxygen and ozone), which can be mitigated by chemical protection (antioxidants and antiozonants).
Technically Specified Rubber (TSR) (also known as Block Rubber) is produced from latex and field coagulum of NR. TSR is high in green strength, tack, easy to mix and has low viscosity. It has good processing characteristics and physical properties.
