Natural rubber sheet LT-8041 Natural rubber is a natural polymer with polyisoprene as a main component, which component is from 91% to 94% hydrocarbon rubber (polyisoprene), the balance of protein, fatty acids ash, sugar and other non-rubber material. Is the most widely used general-purpose rubber. "Natural rubber has high elasticity at room temperature, slightly plastic, having very good mechanical strength, low hysteresis loss, when multiple deformation low heat, so the flex resistance is also very good, and because non-polar rubber, so that good electrical insulation properties. Because there is an unsaturated double bond, so that natural rubber is a chemical reaction ability of substances, light, heat, ozone, radiation, flexing and deformation of copper, manganese and other metals can promote rubber aging, aging intolerance is the Achilles heel of natural rubber, but added antioxidant natural rubber, sometimes months exposure still do not see much change in the sun, in the warehouse storage can still be used as usual after three years Natural rubber has good alkali resistance, but not resistant to concentrated acid. Since the non-polar rubber, natural rubber, some resistance to polar solvents only, whereas in the non-polar solvent swelling, and therefore, its oil resistance and solvent resistance poor, in general, hydrocarbons, halogenated hydrocarbons, carbon disulfide, ethers, higher ketones and higher fatty acids of natural rubber are dissolution, but its solubility is affected by the extent of mastication of the impact, and a lower ketone, lower ester and alcohol class of natural rubber is a non-solvent "Uses: Natural rubber elasticity because it has a strong and good insulation, plasticity, drain trap, tensile strength and wear characteristics, widely used in industry, agriculture, national defense , transportation, machinery manufacturing, medical and health fields and other aspects of daily life. Medium: suitable for medium water, sea water, air, inert gases, alkali, salt water, etc., but the impatience of mineral oil and non-polar solvents, long-term use temperature does not exceed 90 ℃, excellent low temperature performance, -60 ℃ or more.
