2、 物理性能:
Natural rubber sealing ringIt has many excellent physical properties: the rebound rate can reach 50% -80% at 0-100 ℃, the elongation rate is 1000%, the tensile strength of pure rubber is 17-25MPa, the carbon black reinforced vulcanized rubber can reach 25-35MPa, the 500% tensile stress is above 12MPa, the air tightness is good, and the penetration parameter is 2.969X1012H2（S.Pa）-1Similar to SBR, its disadvantage is that it is not resistant to hydrogen based oils and is not suitable for use in ultraviolet radiation, oxygen, and ozone. But its poor weather resistance can be improved by special additives.
