Are O-rings elastomers?
Many O rings are made of elastomers. Elastomer is an umbrella term for a type of polymer that has elastic qualities. An elastomer can be made of natural or synthetic materials or a blend of both. It’s defining quality is that it can stretch and return to its original size.
What is elastomeric ring?
Solid elastomeric rings are compression seals that are used to prevent the leakage of fluid or air. They are made of flexible, elastomeric materials and are capable of repeated contraction and expansion without excessive wear and tear. There are many types of solid elastomeric rings.
What type of rubber is used in O-rings?
Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals.
What material is used for O-ring?
O-rings are mechanical gaskets with a round cross section. They are used to prevent gas and fluid leaks in static and dynamic applications and are manufactured from various types of elastomers. Some of the common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton).
Is polyethylene an elastomer?
With exquisite catalyst design and polymerization regulation, polyethylene thermoplastic elastomers with great mechanical and elastic properties can be obtained.
What is a Viton O-ring?
Viton® O-Rings Viton is a brand of synthetic rubber and fluoropolymer elastomer commonly used in O-rings and other molded extruded goods. Viton is a registered trademark of DuPont and is sometimes generically referred to as FKM.
What are O-ring washers used for?
They are often used when the interface you are sealing is a more complicated shape than a circle. O-rings can do that too if you cut the groove properly. The point of all of them when you are sealing is to make up for unevenness in the metal parts that are going together.
What is EPDM O-ring material?
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals.
What is O-ring durometer?
O-Ring durometer is the hardness of the o-ring material. Durometer scales run numerically from 0-100, with lower numbers indicating softer materials and higher numbers for harder materials. Durometer is just shorthand for “Shore hardness”.
What are the three main properties of elastomeric materials?
Properties of elastomers Elastomers are usually very viscous, so they flow slowly under force, and they also exhibit high elasticity, i.e. the ability to return to their original shape after being stretched or compressed under force, making them more resistant to breaking or cracking.
Is rubber an elastomer?
However, “rubber” and “elastomer” are two ways to describe the same thing — elastomer is a description for any type of elastic material, such as synthetic rubber, while rubber is a specific type of elastomer.
