• Materials of Types Rubber Products

Neoprene Rubber / CR Rubber

- Chloroprene (CR) : Also known by the tradename Neoprene®, polychloroprene was the first synthetic rubber and exhibits generally good ozone, aging, and chemical resistance. It has good mechanical properties over a wide temperature range.

SILICONE Rubber (Cao Su SILICONE)

- Silicone (VMQ) : Silicones possess good insulating properties and tends to be physiologically neutral. However, silicone elastomers have relatively low tensile strength, poor tear and wear resistance.

- Our O-ring compounds are formulated to meet the most stringent industry standards, including NSF, Underwriters Laboratories (UL), Military (MIL-SPEC), Aerospace (AMS), NASA, FDA, USDA, USP, and many customer-specific requirements.

VITON Rubber /  FKM Rubber

- Fluorocarbon (FKM) : Fluorocarbon (FKM) has excellent resistance to high temperature and a broad range of chemicals. Permeability and compression set are excellent.

EPDM Rubber / EPM Rubber

- Ethylene Propylene (EPDM) : EPM (EPR) is a copolymer of ethylene and propylene. EPDM is a terpolymer of ethylene, propylene, and a diene third monomer used for cross-linking.

NBR Rubber / Nitrile Rubber

- Acrylonitrile-Butadiene (NBR) : Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene terpolymer. The acrylonitrile content of nitrile sealing compounds varies considerably (18 to 50%.) Polymers with higher ACN content exhibit less swell in gasoline and aromatic solvents, while lower ACN polymers exhibit better compression set and low temperature flexibility. Polymer is also called Buna-N.

SBR Rubber / Styrene-Butadiene Rubber

Butyl Rubber / IIR Rubber

- Butyl rubber (isobutylene-isoprene rubber or IIR) has a very low permeability rate and good electrical properties, but poor short-term rebound.

Ethylene Acrylic Rubber / AEM Rubber

- Ethylene acrylate is a mixed polymer of ethylene, methyl acrylate and a small amount of carboxylated cure-site monomer. Developed as a lower-temperature version of Polyacrylate, but swells slightly more. Polymer is sold under the tradename VAMAC®.

 Fluorosilicone Rubber / FVMQ Rubber 

- Fluorosilicone is a silicone polymer chains with fluorinated side-chains for improved oil and fuel resistance. The mechanical and physical properties are very similar to those of silicone.

 Hydrogenated Nitrile Rubber / HNBR Rubber 

- Hydrogenated nitrile was developed as an air-resistant variant of nitrile rubber. In HNBR, the carbon-carbon double bonds in the main polymer chain are saturated with hydrogen atoms in a process called “hydrogenation” that improves the material’s thermal stability and oxidation resistance.

Perfluoroelastomer Rubber / FFKM Rubber

- Perfluoroelastomer is a rubber version of PTFE. Available from Parker under the tradenames Parofluor™ and Parofluor ULTRA™.

Acrylic Rubber/ ACM Rubber

- ACM (acrylic rubber) has good resistance to mineral oil, oxygen and ozone. The water compatibility and cold flexibility of ACM are considerably worse than with NBR.

POLYURETHANE (AU, EU)

- Polyurethane elastomers have excellent wear resistance, high tensile strength and high elasticity in comparison with any other elastomers. Permeability is good and comparable with butyl. Millable urethanes should not be confused with thermoplastic urethanes, which are generally harder, less flexible, and have slightly better wear resistance.

Application of Rubber Products

Rubber Gasket Material

We can manufacture rubber gaskets to any dimensions and in any shape, from any type of rubber. Whether you are after a standard part, or something bespoke, simply give us a call or send us your drawing and we will be happy to offer you a quotation.

General Information About Rubbers

Rubber is the most important class of materials for sealing in the medium temperature range (-50ºC to +120ºC). This is because rubbers rapidly return to their original shape when any deforming stress or load is removed.

Parts can be manufactured from the following rubbers; natural, neoprene, nitrile, EPDM, silicone, viton, styrene butadiene, butadiene acreionitrile, ethylene propylene, butyl and hypalon.

Many rubbers are available for various working conditions; however they all have one property in common – the effect of heat is cumulative and irreversible. They can be used in a variety of working conditions; typically used with water, oils, chemical and other low pressure fluid applications. Examples of rubber gaskets include everything from standard pipe gaskets, to oil and manway gaskets.

The kind of rubber gasket you require will depend upon what you want it to do and the conditions in which you want it to operate. For instance, if your application involves water you should consider using neoprene or EPDM. If you require a part with oil and fuel resistance, you should consider nitrile or Viton®. The properties of the gasket will depend upon the type of rubber from which it is manufactured.

Maximum temperatures must not be exceeded and a good design will allow a safety margin dependent on design sevice life.

Many rubbers are available in foam (sponge) form for simple gasket sealing applications.

If you can’t find what you’re looking for or require a bespoke material, please do not hesitate to contact us.

Buna-N/Nitrile Rubber

Buna-N is the American term for Nitrile rubber, it is also known as: Butadiene Acrilonitrile, Perbunan or NBR rubber. Grades vary on their properties due to their acrylonitrile content. A high acrylonitrile content has a better oil resistance while a low acrylonitrile content has better resilience and low temperature flexibility.

Nitrile has outstanding resistance to: oils, petrols, solvents and lubricants but has poor ozone resistance. As such, nitrile gaskets are particularly suited for use with fats, oils, fuels and other liquids contaminated by these.

We stock nitrile in commercial, specification and white food quality grades. It is ideally used in temperatures ranging from -20ºC to +110ºC (Dependant on grade).

Popular examples of gaskets made from nitrile are: Oil gaskets and Cover gaskets.
