The Coi Rubber Blog is where you’ll learn about molded rubber products and more. Topics include molded part design, elastomer selection, and injection, compression, and transfer molding of custom rubber products for OEMs.
Rubber is a polymer which can stretch and shrink. It occurs naturally and can be synthesized as well. We have been using rubber products since ancient times. But during the 19th century it became a highly useful industrial raw product for various purposes.
Rubber can be divided into following two types based on its origin –
Natural Rubber
Synthetic Rubber
There is a wide variety of synthetic rubber available such as EPDM (Ethylene Propylene Diene Monomer) rubber, commercial black rubber, SBR (Styrene butadiene rubber), NBR (nitrile butadiene rubber), IIR (Isobutylene-isoprene) etc.
Natural rubber is a natural polymer of organic compound isoprene obtained from the bark of tropical and subtropical trees. The milky white fluid which is obtained from trees is called latex. This is the reason natural rubber is also known as latex. Natural rubber is also called India rubber, Amazonian rubber and caucho. Leading producers of natural rubber are Thailand and Indonesia.
Monomer Unit of Natural Rubber – 2-methyl 1,3-butadiene (it is also called isoprene)
Structure of Natural Rubber – It is called polyisoprene or cis-1,4-polyisoprene. Its structure is given below –
Natural rubber or rubber latex is directly collected from plants. Then it is processed for common use by various methods. It is a polymer of 2-methyl 1,3-butadiene (or isoprene).

The modern rubber molding machine was actually adopted from the plastic molding process known as injection molding. Injection molding is a manufacturing process to make molded products by injecting a heated raw material into a mold cavity in which it is cooled and hardened into the mold shape. This system of manufacturing is still being […]

Rubber is in almost everything we can get our hands on, and we cannot go a day without using rubber. Although rubber is a renewable resource, it is still creating many problems for the environment when they are improperly disposed of. When rubber is burnt, it lets out many harmful gases. When people dump tires […]
Rubber is an extremely adaptable material. It can be utilized for various commercial and mechanical applications. From rubber plugs, tires, sealing components, and other unique products, you can discover various things constructed with this material. If you are a vendor of rubber products, it is imperative that you only do business with the most reliable […]
When you’re looking for a custom rubber manufacturer, you should already have in mind what sort of product(s) you want – be it a drawing or sample. Next you need to know what type of rubber material you require from your manufacturer. Do you know the types of rubber available? Rubber products can be made […]
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the […]
