Raw rubbers can’t be used in their natural state. The raw rubber mixed with the right type of additives will get us to the optimum properties of rubber products, rubber seal rings, Rubber O rings, Rubber gasket seals etc… Rubber processing and compounding has utmost importance.
The additives in a rubber processing and compounding may vary from application to application. The additives are added by weight and will include some or all of the following:
Sulphur and peroxide curing are used as cross linking curatives for rubber chains and best known curatives in rubber processing and compounding. They are first to get discovered and most commonly used.
Accelerators are used to fasten the speed of curing without harming the properties.
This are the materials strengthen the finished products like rubber products, Rubber seal rings, Rubber O rings, Rubber gasket seals etc… . Most of the black colour rubber products use Carbon black and other colour use silica.
Clays are used to reduce the cost of compounds. It can disturb the properties.
Pigments are used to have desired colours. (Pigments are used where carbon black is not used as reinforcing agent).
It just helps to process and sometimes to have some properties.
"ONGC - Oil and Natural Gas Corporation Limited" - Our complex drilling application where Shaft was eccentric and application was robust & muddy. Replacement was never easy. Mech Spares designed Oil seals resolved difficulty. This gave a complete joy to my maintenance team.
"Mr Mohammed Al Duaigy" of (Kuwait National Petroleum Company) : We tried several diaphragms from renown worldwide Rubber manufacturing companies. We found Mech Spares technical know how and product to be of great durability and lasted 3 times more then anticipated. They have accurate understanding of there products.
"McCafferty BM Design Ltd, KENT United Kingdom" - Most of the O rings manufacturing company suggested to use larger diameter and expensive elastomers. We learnt with Mech Spares that elastomer being weaker compare to metal and alloys and needs appropriate back up for high pressure or high vacuum applications. Further not necessary the most expensive elastomer is the best for all applications. We trust Mr Nilesh chodhari completely for all our O rings designing applications.
"Dr. A. Singh" of BARC: The electric Insulation mat manufactured by MECH SPARES as per IS 15624 tested at ERTL and found to withstand 40 Kv and still didn't tear. We have been using since 5 years and still didn't generate any fatigue. They arranged bulk delivery in short period.
"Tata Steel" - One of our old machines started making loud noise and disturbed the entire village. We were compelled to stop the machines which lead to huge production loss. With the help of Mech Spares designed bellows in two part we could retain the lubrication and eliminate the noise.
