What are the different types of elastomer?

What are the different types of elastomer?

Four common elastomers are cis-polyisoprene (natural rubber, NR), cis-polybutadiene (butadiene rubber, BR), styrene-butadiene rubber (SBR), and ethylene-propylene monomer (EPM).

What is the difference between Kalrez and Viton?

The name Kalrez® is a trademark of Dupont. The material is actually an improved version of Viton with 20% more fluorine in the chains, making it an extremely expensive per fluorocarbon elastomer.

What are elastomers used for?

Elastomer are used for rubber tires and tubes for vehicles, motorcycles, bicycles and recreational vehicles, lawn mowers and other yard work vehicles, belts, hoses, gloves, matting, toy balloons, rubber bands, adhesives and pencil erasers.

What is kalrez made of?

It is a carbon black filled product with excellent chemical resistance, good mechanical properties, and outstanding hot air aging properties. It exhibits low swell in organic acids, inorganic acids and aldehydes, and has good response to temperature cycling effects.

What is the difference between elastomer and rubber?

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.

Is elastomer the same as silicone?

Is a polymer that displays elastic properties. A part from Latex (the natural product), most elastomeric products fall into the category of “Synthetic Elastomer” the use of the word elastomer is used interchangeably with rubber nevertheless, Silicone is more correctly an “elastomer”.

Is FKM same as PTFE?

FKM offers greater temperature resistance but falls short of PTFE’s properties in terms of chemical resistance. While PTFE is slightly less thermally resistant but offers much in the way of non-adhesive properties. It’s a dead heat!

Are Viton and FKM the same?

These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.

Is elastomer a plastic?

Elastomer is shorthand for elastic polymer. Elastomers are viscoelastic: sticky, very elastic polymers (plastics). Natural rubber is an elastomer made from latex, a milky tree sap. Synthetic elastomers are made from petroleum.

Is Kalrez a PTFE?

In addition, Kalrez® is a thermoset perfluoroelastomer part and offers excellent elastic properties and resistance to mechanical damage, unlike PTFE which is a thermoplastic and appears to lack the necessary resilience to withstand mechanical shock in a process application such as this.

What is the difference between Chemraz and Kalrez?

The effective temperature range for Kalrez is +5ºF to + 600ºF, for Chemraz –20ºF to +450ºF. A white Chemraz compound is available and features less impurities and less electrical conductivity.

Is silicone an elastomer?

A part from Latex (the natural product), most elastomeric products fall into the category of “Synthetic Elastomer” the use of the word elastomer is used interchangeably with rubber nevertheless, Silicone is more correctly an “elastomer”.

Is PVC an elastomer?

Both polyvinyl chloride (PVC) and thermoplastic elastomer (TPE) are materials used for caps and plugs. PVC is incredibly versatile and can be formulated to be rigid or soft.

Resistance PVC TPE
Alcohol Good – excellent Excellent

Is silicone elastomer a rubber?

Which is better Viton or PTFE?

Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.

Is Viton same as FKM?

Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same. Originally developed by Du Pont, it is produced by a number of companies around the world.

Is PTFE better than Viton?

Oil Resistance: Poor

Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.

Is elastomer a silicone?

What is the difference between rubber and elastomer?

Is Kalrez the same as Teflon?

Is Teflon an elastomer?

Fluoroelastomer (FKM) rubber is a thermoset elastomer while Polytetrafluoroethylene (PTFE) is a thermoplastic. Both are fluorinated materials comprising of carbon atoms surrounded by fluorine atoms, which gives them incredible chemical resistance.

Is fluorocarbon FKM the same as Viton?

Is FFKM same as FKM?

What is FFKM? FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, and features higher temperature ratings, up to approximately 325°C. FFKM also has improved chemical resistance, with nearly universal chemical compatibility.

Which materials are called elastomers?

Rubber-like solids with elastic properties are called elastomers. Polymer chains are held together in these materials by relatively weak intermolecular bonds, which permit the polymers to stretch in response to macroscopic stresses.

Is TPE better than PVC?

It’s PVC’s flexibility and high mechanical strength that makes it a popular choice for caps and plugs. Like PVC, TPE is also versatile.

Resistance PVC TPE
Low-temperature flexibility Poor – good Best
Weather, including sun Good – excellent Best
Ozone Excellent Excellent
Abrasion Fair – good Excellent
