Southbourne Rubber uses the highest quality materials to manufacture a wide range of rubber parts for machinery and applications, including everything from aeroplanes and helicopters to showers and audio equipment.

We use British Standard, and Department of Technical Development (DTD) for our military customers, specification materials from approved suppliers. These have been fully tested and released with certificates of conformance and testing. All parts manufactured are fully batch traceable and documented.

Whether we are punching gaskets and seals from sheet or compression moulding o-rings and bellows, the types of rubber used for our parts include: natural rubber, nitrile, chloroprene, neoprene, butyl, EPDM, Hypalon, polyurethane, fluorocarbon, silicone, fluorosilicone and silver loaded silicone.

The full range of the materials used by Southbourne Rubber are listed below:

Polytetrafluoroethylene (PTFE)

Also known as Teflon, polytetrafluoroethylene (PTFE) is a hydrophobic synthetic fluoropolymer that cannot be wetted by water. Often used for its non-stick coating on cookware, the casings of communications devices, to provide an antibacterial barrier for catheters, as a non-reactive barrier in the pipework of corrosive chemicals and as a lubricant to reduce friction, Southbourne Rubber makes the most of PTFE to manufacture a wide variety of parts for numerous applications.

Hydrogenated Nitrile Rubber (HNBR)

With its good mechanical properties and resistance to oil, gas, hot water and abrasion, HNBR is used widely in the transport, industrial and oil and gas sectors. Offering heat resistance up to 140°C as well as standing up to adverse environmental conditions, Southbourne Rubber often uses HBNR in the manufacture of rubber seals for gear boxes and rubber gaskets with a long service life.

Fluorosilicone rubber (FVMQ)

Similar to silicone rubber, this elastomer has a better resistance to fuels, oils and lubricants. However, while it performs well at a wide range of working temperatures, its resistance to hot air is not as good as that of silicone. That said, it holds its own when it comes to weathering and ozone exposure and has sound electrical strength, making it an excellent choice for use in aerospace fuel systems [Industry]. Southbourne Rubber manufactures high quality gaskets, seals and o-rings made from fluorosilicone rubber in a number of sizes and for a number of technologically advanced industries.

Hypalon® rubber (CSM)

A brand of chlorosulfonated polyethylene (CSM), this synthetic rubber is resistant to chemicals, weathering and water. With a temperature range of -35ºC to +125ºC and the ability to self-extinguish, Hypalon or CSM rubber sheeting is used at Southbourne Rubber to make static rubber seals and are the ideal option when manufacturing Personal Protective Equipment (PPE).

Polybutadiene (BR)

With its hard-wearing and non-conductive nature, polybutadiene is an ideal compound for creating tough rubber parts, and coating parts particularly for electronic assembly. The second largest volume synthetic rubber produced after SBR and performing well at low temperatures, the elastomer of polybutadiene is of particular use in the transport industry [Industries] to improve the tread of car and truck tyres.

Butyl rubber (IIR)

Also called isobutylene-isoprene rubber (IIR), butyl is impermeable to gases, resistant to water, steam and weathering. A copolymer of isobutylene and a small amount of isoprene, this synthetic rubber is regularly used in precision engineering as rubber sealants and in the industrial sector [Industries] for everything from damp proofing and roofing to tyre inners and protective clothing.

Silicone rubber (VMQ)

Known for its non-conductive nature, good flame and moisture resistance, endurance in extremes of temperature (-62ºC to 204ºC) and hygienic properties, silicone is used for a number of applications in industries ranging healthcare and food to industrial and automotive. Made up of silicon, carbon, hydrogen and oxygen, silicone rubber is used by Southbourne Rubber to create silicone rubber gaskets, sealants and o-rings [Products], to name but a few.

Styrene Butadiene Rubber (SBR)

SBR is a synthetic rubber that is commonly used as a substitute for natural rubber who it outweighs in abrasion-resistance but is inferior to in fatigue-resistance. A fantastic general purpose elastomer, SBR can be used by Southbourne Rubber to manufacture everything from the soles of shoes to car tyres. A copolymer of styrene and butadiene, the syrene content determines this rubber’s flexibility and toughness.

Nitrile Rubber (NBR)

Also known as nitrile-butadiene, acrylonitrile butadiene rubber and Buna-N, NBR is a polymer made by reaction of butadiene and acrylonitrile. Because it has a high resistance to oil which becomes more prevalent with the increase of nitrile in its makeup, this is the ideal copolymer for rubber seals and gaskets for the transport sector as well as printing rolls and hoses for the industrial sector [Industries].

Neoprene or polychloroprene (CR)

A family of synthetic rubbers produced by polymerisation of chloroprene, neoprene has sound chemical stability and remains flexible over a wide temperature range. Neoprene is available to us as either solid rubber or in latex form and we use it manufacture a wide range of applications including: laptop sleeves, orthopaedic braces and electrical insulation.

Ethylene Propylene Diene Monomers (EPDM)

Recognised for its high density and durability, this synthetic rubber is made up of ethylene and propylene, which originate from oil and natural gas. Able to maintain performance in extremes of temperature with a shrewd resistance to weathering and oxidisation, EPDM is excellent for outdoor use and an industry favourite for rubber roofing as well as rubber gaskets and seals.

Natural / isoprene (NR)

A polymer of isoprene with a molecular weight of 100,000-1,000,000, this super resilient organic material can also contain traces of proteins and resins. Natural rubber latex is derived from the bark of trees such as Hevea brasiliensis or the “rubber tree”, which is native to South America and accounts for almost 100% of the world’s supply. This is then dried to give natural rubber. While isoprene is not strictly natural rubber, it is very similar in terms of structural and chemical composition and is easier to produce. Known for their elasticity, tensile strength and abrasion resistance, natural rubber and isoprene can be used for similar
