Hopeful Rubber employs a range of materials to produce customized molded rubber components that satisfy their clients’ distinct needs and specifications.

Why are rubber materials called elastomers?

Rubbers are called elastomers because they are a type of polymer that exhibits elastomeric properties, meaning they can undergo elastic deformation when subjected to stress and then return to their original shape when the stress is removed. The term “elastomer” comes from the words “elastic polymer,” reflecting this ability to stretch and recover without undergoing permanent deformation.

While the term “rubber” originally referred specifically to natural rubber, which is derived from the sap of rubber trees, the term “elastomer” is more commonly used today to describe both natural and synthetic rubber materials. This reflects the fact that all rubber materials, whether natural or synthetic, share the common property of elastomeric behavior.

There are many different types of elastomers, each with its own unique set of properties and characteristics that make it suitable for specific applications. Here are some examples of common types of elastomers:

A Guide to Common Elastomers and Their Unique Characteristics

Silicone Rubber (SR)

A synthetic elastomer that is known for its excellent heat resistance and chemical stability. It can withstand extreme temperatures and is often used in high-temperature applications such as gaskets, seals, and electrical insulation.

Liquid Silicone Rubber (LSR)

A synthetic elastomer that is composed of high-purity silicone with low levels of volatile materials. It is often used in the production of medical devices, automotive parts, and consumer products. LSR has excellent thermal stability, resistance to aging, and can be easily molded into complex shapes. It is also biocompatible and can be sterilized, making it suitable for use in medical applications.
