What's the difference between Butyl Rubber Monomer and Natural Rubber?

Butyl Rubber Monomer, also known as isobutylene-isoprene or IIR, and Natural Rubber, derived from latex of Hevea brasilensis, differ in several ways.

Step 1: Raw Material.

The raw materials for Butyl Rubber Monomer and Natural Rubber are different. Butyl Rubber Monomer is made from a mixture of isobutylene and isoprene, while Natural Rubber comes from the sap or latex of the rubber tree.

Step 2: Properties.

The properties of Butyl Rubber Monomer and Natural Rubber are also different. Butyl Rubber Monomer has a lower level of unsaturation than Natural Rubber, making it more resistant to oxidative degradation and better at sealing. Natural Rubber, on the other hand, is highly elastic and can stretch up to eight times its original size without breaking.

Step 3: Production.

The production processes for Butyl Rubber Monomer and Natural Rubber also differ. Butyl Rubber Monomer is typically produced using a series of chemical reactions, including chlorination and polymerization. Natural Rubber, on the other hand, is harvested from the rubber tree and undergoes a process of coagulation, centrifugation, and washing to remove impurities.

Step 4: Uses.

The uses of Butyl Rubber Monomer and Natural Rubber are also different. Butyl Rubber Monomer is often used in the manufacture of adhesives, sealants, and coatings, as well as in the production of inner tubes for tires. Natural Rubber is used in a variety of products, including tires, gloves, clothing, and toys.

In conclusion, while Butyl Rubber Monomer and Natural Rubber may share some similarities, such as their elastic properties, the differences in their raw materials, properties, production processes, and uses make them distinct substances with unique qualities.
