Rubber cords

At Power Rubber, we offer rubber cords made of high-quality components, characterized by high strength and long service life. The offer includes cords made of NBR, FKM, Silikon, VMQ, FPM, CR rubber.

Types of rubber cords

A wide range of rubber cords means that their type can be adapted to individual needs.

NBR rubber cords (nitrile)

NBR is a rubber made of acrylonitrile-butadiene rubber. It shows high resistance to petroleum oils, fluids based on mineral oils, vegetable oils, greases, water. Withstands temperatures from -30 ° C to +120 ° C. Breaking strength is its advantage. Rubbers made of this material are characterized by low susceptibility to both atmospheric factors and ozone.

Square NBR cords

square rubber cord

Made of acrylonitrile-butadiene rubber. Intended for contact with petroleum derivatives, animal oils, vegetable oils, lubricants, hydraulic fluids, mineral oils. It has good mechanical properties (resistant to deformation, abrasion). Can be operated in temperatures from -30 ° C to +120 ° C. Their advantage is compatibility with HFA, HFB, HFC fluids (HSA, HSB, HSC). They are not resistant to ozone and UV radiation. They show low resistance to high sunlight and weather conditions.

EPDM rubber cords

Epdm rubber cord

EPDM cords are made of synthetic ethylene-propylene-diene rubber. Products made of this type of rubber are resistant to weather conditions, ozone, sunlight, UV rays, moisture and water vapor. Thanks to these properties, rubber cords can be successfully used outdoors. Additionally, it is resistant to brake fluids and hydraulic fluids. This type of rubber is not resistant to greases, oils and fuels. Withstands temperatures from -45 ° C to +120 ° C.

FMK / FPM rubber cords

It is a fluoro rubber which is highly resistant to ozone, oxygen, UV radiation and corrosive liquids. It is characterized by good mechanical properties, resistance to damage and the effects of extreme temperatures. Additionally, the rope made of FMK / FPM is gas-tight. The temperature range is within
in the range from -25 ° C to even +210 ° C.

Silicone cords up to 200 ° C / up to 300 ° C

silicone rubber cord

On the market, the sales offer also includes silicone ropes, which are characterized by low toxicity, resistance to the development of bacteria and fungi, and thermal stability.
For this reason, they are often used in the food, medical and pharmaceutical industries. They also make a good electrical insulator. The great advantage of silicone cords is the ability to remain flexible in the temperature range from -60 ° C to +200 ° C. The choice of this type of product depends on the hardness scale (from 40 Sha to 80Sha). There are also high-temperature silicone cords operating at temperatures from -60 ° C to +300 ° C. They are resistant to oxygen, nitrogen and weather conditions. They are not suitable for contact with oils and solvents – they are chemically non-resistant.

Square silicone cords

They are characterized by excellent resistance to UV radiation, oxygen, ozone and sunlight. Like round cords, they are resistant to biological and fungal attack. They have good electrical insulation properties. They are durable and have a wide temperature range in which they work (from -60 ° C to +200 ° C). They are not intended for contact with chemical substances. They are available in various hardness levels.

EPDM sponge cords

Rope epdm spongy

They show excellent resistance to ozone, unfavorable weather conditions, UV radiation, moisture and water vapor. They are characterized by thermal insensitivity. EPDM sponge cords are flexible and will be great for sealing windows, doors or brake systems. The temperature range is from -30 ° C to +120 ° C. This type of sponge ropes is not intended for contact with petroleum oils, grease or fuel.

CR (chloroprene) cords

CR is a rubber made of chloroprene rubber, also known as Neoprene. It is not susceptible to ozone and weather conditions, so it can be used outdoors. A wide operating temperature range (from -40 ° C to +110 ° C) is an advantage of this type of rubber. It also has good mechanical properties. It is characterized by good resistance to fire and chemicals.

Rubber cords – application

It is a gasket with a round or square section, called a rubber cord or O-ring cord, which has various functions.


Depending on the cross-section and thickness of the cord, they can be widely used in:


  • automotive industry
  • shipbuilding
  • food industry
  • oil industry
  • pharmaceutical industry
  • households
  • sanitary installations
  • household appliances
  • construction
  • agricultural machinery
  • in everyday life (sealing windows, doors, floors)
