Buying Rubber Profiles

18.08.2021

Rubber profiles – materials and usage

Rubber profiles are produced from various rubber compounds. The most common are SBR (general-purpose), NBR (oil-resistant), EPDM (weatherproof). Less common are CR (Neoprene), FKM/Viton, and MVQ/Silicone. Polyurethane profiles are available as custom options. It’s crucial to choose a supplier offering custom rubber seals, ensuring precise fitting gaskets. Check manufacturer reputation and available rubber gasket materials before purchasing.

Material properties explained

NBR – nitrile rubber

Highly resistant to solvents, oils, greases, fuels. Flexible and widely used for oil-resistant seals.

SBR – styrene-butadiene

Tough, tear-resistant, heat-aged. Ideal for general-purpose rubber seals and washers.

EPDM – ethylene-propylene

Excellent chemical, UV, ozone resistance; works between –50 °C and +130 °C (up to +150 °C). Ideal for outdoor sealing profiles.

CR – neoprene

Weather-resistant, hard-wearing, retains flexibility under frequent flexing.

FKM/Viton – fluoro rubber

Outstanding chemical resistance (fuels, acids, solvents, oils), stable from –40 °C to +250 °C. Long-lasting industrial seals.

MVQ – silicone

Operates from –60 °C to +200 °C, UV-resistant, flame-retardant. Suited to food-grade and medical sealing.

Shared features of rubber profiles

  • High mechanical strength

  • Durable under harsh weather conditions

  • Designed for sealing applications

  • Available in various Shore hardness levels

  • Reinforcements possible (e.g. wire or fabric)

  • Excellent in compression and extension

  • Some are food-contact certified

Material selection depends on exposure conditions: oils (NBR), acids (EPDM), static (MVQ), etc.

Sales and delivery options

Rubber and silicone profiles are available in-stock and as custom-made seals. Standard delivery typically takes a few days; custom orders may be delayed. Many suppliers offer fast delivery, but bespoke profiles will follow the seller’s production timelines. Contact us to discuss bulk pricing or custom requirements.
