Black Natural Rubber Gasket
Style KXT 1700N Pure Natural Rubber Gasket
Natural rubber 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 (NR) seals also resist tear and abrasion, and can resist shear and compression
for long periods in the absence of tension
Advantages:
• Have good resistance to moderate chemicals, dry organic acids
• Excellent water resistant and tear resistant
• Good abrasion resistance, high elasticity
• High tensile strength
• High elongation
• Good recovery., etc
Application:
• Alcohols, ketones and aldehydes
• Moderate chemical industries
• Wet or dry organic acids
• Weak acid and alkali
• Chemical tubing
• Shock absorber
• Ammonia., etc
