Rubber and Sponge Cord

Rubber and Sponge Cord

Rubber and sponge cord, often known as “rubber rope” or “sponge rope,” is widely employed in sealing applications where a moulded O-ring of the precise size is not available. We have rubber cords made of EPDM, neoprene, nitrile, silicone, and Viton® ‘A’ that may be linked together using a variety of adhesives (available to purchase separately). Rubber cable is available in a variety of sizes, ranging from 1mm to 40mm* in diameter, and may be utilized in a variety of sectors, including automotive, aviation, chemical, electrical, environmental, petrochemical, food, and pharmaceutical. On request, we can provide different diameters, coil sizes, rubber materials, and scarf jointed vulcanised O-rings.

Our closed cell sponge cables come in two different material options: neoprene and silicone, each with its own set of benefits. In comparison to rubber alternatives, these materials are easier to compress and handle, and they may be utilized in both inside and outdoor contexts. High-temperature seals for doors and ovens, external electrical seals, and food processing machinery seals are all common uses for silicone sponge rubber cords. When equipment is in operation, the neoprene sponge cord is widely used as an effective seal to keep gas, liquid, and dust from escaping, or as an alternative to foam backer rods.

Rubber and sponge rope may be made in a variety of materials and sizes to meet your needs. If you need help determining which type of cord is best for your application, please contact our technical sales team, who would be pleased to help. Our chemical compatibility chart, on the other hand, may be able to assist you in determining the acceptability of the material you require when in contact with specific chemicals.

For additional information on the many varieties of cords available, please see the links below.

Rubber Cord

EPDM Rubber Cord

Manufactured from a synthetic blend of ethylene, propylene and a diene comonomer. EPDM provides excellent resistance to diluted acids, ageing, ozone and weathering. It is primarily used in exterior sealing applications. Temperature range: -50°C up to +130°C.

Neoprene Rubber Cord

Providing good strength, flexibility and resistance to abrasion. Neoprene rubber cord is a good, general purpose sealing material and is used in applications that require resistance to weathering, ageing, ozone and mild acids. Temperature range: -35°C up to +110°C.

Nitrile Rubber Cord

Offering excellent resistance to petroleum, greases and oils. Nitrile rubber cord is primarily used in automotive, gas and petrochemical sealing applications. It also provides good resistance to abrasion. Temperature range -30°C up to +120°C.

Silicone Rubber Cord

Available in a selection of colours, silicone rubber cord has a non-stick surface and offers excellent compressibility across a broad temperature range. All options are WRAS approved and conform with FDA and EC food contact regulations. Temperature: -40°C up to +200°C.

Silicone Rubber Cord – Metal Detectable

Manufactured from an FDA approved elastomer that contains additives which are visible to metal detector scanning equipment. Metal detectable silicone is popular in the food industry as it helps to identify product contamination. Temperature: -60°C up to +200°C.

Viton® ‘A’ Rubber Cord

Manufactured from a branded flouroelastomer that offers unrivalled resistance to hydrocarbons, organic solvents, petrochemicals and mineral acids. Viton® ‘A’ rubber cord is commonly used in automotive, gas and petrochemical sealing applications. Temperature range: -20°C up to +275°C.

Sponge Cord

Neoprene Sponge Cord

Neoprene sponge cord is manufactured from a high quality closed cell sponge rubber that is easily compressed and highly pliable. It displays the same characteristics as neoprene rubber cord, but is softer and easier to manipulate. It is commonly used to isolate liquid, gas and air. Temperature: -40°C up to +90°C.

Silicone Sponge Cord

Available in a range of grades including; flame retardant, food approved and metal detectable. Silicone sponge cord is highly compressible, offers excellent temperature resistance and is a good electrical insulator. It is used in the food industry and in electrical enclosures. Temperature: -40°C up to +200°C.

Alternative Cord

Polyurethane Cord & Tube

Available in a range of finishes and shore hardness’s, polyurethane cord and tube is tough, durable and offers very low coefficient of friction. They are commonly joined to create endless lengths for use in power transmission and line shaft conveyor applications. Temperature: -30°C up to +80°C.

PVC Cord

Providing good strength, excellent chemical resistance and moderate flexibility. PVC cord is commonly used in textile covers as Keder cord or power transmission applications. It conforms with EC food contact regulations and is extremely durable. Temperature: -20°C up to +65°C.
