Rubber-cork gaskets
Cork rubber for gaskets is a technical material that combines the flexibility of rubber with the resistance and resilience of cork. We offer cork rubber in rolls and cork rubber sheets, designed for sealing applications in automotive, machinery, and technical industries. The cork rubber sheet effectively dampens vibrations and is resistant to oils, fuels, and water.
At Power Rubber, we offer custom cutting of gaskets from cork rubber, allowing the production of tailored sealing elements for specific applications.
What are cork gaskets and what are they used for?
Cork rubber gasket is a technical sealing element made of a composite of cork granules and elastomer, most commonly NBR or EPDM rubber. The combination of these materials provides exceptional properties: resistance to oils, fuels, water, greases, and vibrations, while maintaining flexibility and the ability to compensate for surface irregularities. Cork rubber gaskets are used in automotive, hydraulics, machine construction, industrial equipment, and technical apparatus, especially in low-pressure flat connections. Thanks to the material structure, they enable a tight and durable seal even with slight compression.
Power Rubber also offers custom cutting of cork rubber gaskets according to the client's technical documentation.
What properties does rubber sealant have?
Rubber cork is a composite material that combines particles of rubber and cork, created through the process of vulcanization and mixing. It combines the flexibility of rubber with the high compressive strength of cork. It adapts perfectly to surfaces, compensating for their unevenness, while ensuring tightness even with minimal pressure. Rubber cork for gaskets is characterized by exceptional resistance to oil. It does not deform or degrade, even after prolonged immersion in oils, making it ideal for sealing parts such as oil pans in cars or motorcycles. Another important feature of rubber cork in sheets and rolls is its compressibility and elasticity. The material does not deform and returns to its original shape after the pressure is released. Rubber cork withstands impacts and vibrations during the operation of equipment, and effectively dampens noise.
What is the difference between a cork-rubber sheet and a rubber-cork sheet?
Although the terms "cork-rubber sheet" and "rubber-cork sheet" are sometimes used interchangeably, they technically refer to differences in the format and application of the material. A "cork-rubber sheet" is a thicker, stiffer semi-finished product, usually produced in large formats with a thickness ranging from 2 to 10 mm. It is mainly used in the production of technical gaskets, anti-vibration pads, and industrial insulation. On the other hand, a "rubber-cork sheet" has a smaller thickness and greater flexibility, allowing for better adaptation to surfaces when cutting gaskets with precise shapes. Both materials are made by combining cork granules with elastomer, usually NBR or EPDM rubber, providing them with resistance to oils, fuels, water, and varying temperatures. In practice, the choice between a sheet and a cork depends on the processing method and application requirements. Power Rubber offers both cork-rubber sheets and rubber-cork sheets, as well as a custom cutting service, allowing for the production of elements perfectly tailored to the customer's technical needs.
Where to buy rubber bands for seals?
A professional rubber cork for gaskets is worth purchasing directly from a technical materials manufacturer, such as POWER Rubber. The company offers rubber cork in sheets and rolls, designed for the production of technical seals, damping elements, and anti-vibration pads. The material combines the flexibility of rubber with the resilience of cork, ensuring excellent sealing and durability in industrial conditions. Power Rubber also provides custom cutting of rubber cork and production of finished gaskets from rubber cork according to the client's technical documentation, guaranteeing precise fitting and high-quality craftsmanship.
