ELASTOMERS: GAMMA STERILIZATION

Guide to Ratings in Sterilization Chart

Note: “Damage” refers to significant changes that affect the physical properties; other effects like discoloration may occur at lower doses.

  • Excellent: Doses of more than 100 Mrads may not cause significant damage.
  • Good: Doses in range of 20 to 100 Mrads may cause significant damage.
  • Fair: Doses in range of 5 to 20 Mrads may cause significant damage.
  • Poor: Significant damage may occur at doses of 2 Mrads or less.

Material Stability Comments
Butyl Fair
Ethylene-Polyproylene Oiene Excellent
Fluoro Good
Natural Excellent
Nitrile Fair Discoloration is normal
Polyacrylic Good
Polychloroprene (Neoprene) Good Some discoloration. Aaromatic plasticizers improve stability.
Silicones Good Phenyl substituted materials are more stable than methyl silicones.
Styrene-Butadiene Excellent
Urethane Excellent
