Description

Natural Gum Rubber Gasket

Natural rubber sheet offers an extensive line of natural rubber sheet material with excellent physical properties making it ideal for use in the marine industry, conveyor belt operations and gaskets applications.  Natural rubber displays outstanding tensile strength, elongation and abrasion resistance. It performs well in low temperatures retaining its flexibility and compression set while displaying excellent adhesion to fabric and metals.

 

Also known as gum rubber, natural rubber is a soft, supple, and flexible non-marking rubber manufactured from rubber trees sap. It is this source of materials extracted from trees that makes natural rubber an eco-friendly elastomer. Natural rubber is in high demand in the automotive and military industries. Advantages when using natural rubber is it has a long service life, superior abrasion resistance, high tensile strength, excellent tear resistance, and outstanding elongation properties. The disadvantages of natural rubber is it is not recommended for oil and solvent and has poor ozone resistance

 

Natural rubber gum gaskets provide superior dynamic sealing. They have a low level of damping and good low temperature properties, and mate well with metal surfaces. Natural rubber seals also resist tear and abrasion, and can resist shear and compression for long periods in the absence of tension.

When subjected to tension, however, Natural rubber gum gasket may experience ozone cracking. That’s why our Products can also recommend synthetic rubber gaskets, if that’s what your application requires. Ask us about all of your choices for gasket material, and we’ll recommend the right elastomer.
