Natural rubber is made from natural rubber
plant rubber. Commercially available natural rubber is produced primarily from
latex of the trilobata tree. Natural rubber is a polyprenylate as the main
component of the natural polymer compounds, the formula is (C5H8) n, the
composition of 91% to 94% of rubber hydrocarbons (polyisoprene), the rest of
the protein , Fatty acids, ash, sugar and other non-rubber substances.
Natural attributes
1. Physical properties. Natural rubber at
room temperature with high elasticity, slightly plastic, has a very good mechanical
strength, hysteresis loss is small, in a number of deformation heat is low, so
its resistance to flexion is also very good, and because it is non-polar
Rubber, so the electrical insulation performance is good.
2. Chemical properties. Because there are
unsaturated double bonds, so natural rubber is a strong chemical reaction of
the material, light, heat, ozone, radiation, flexural deformation and copper,
manganese and other metals can promote the aging of rubber, aging is natural
Achilles heel of rubber, however, added the antioxidant natural rubber,
sometimes in the sun exposure two months still do not see much change in the
warehouse after three years of storage can still be used as usual.
3. Resistance to dielectric properties.
Natural rubber has good alkali resistance, but not strong acid. Since the
natural rubber is non-polar rubber can only resist some polar solvents, and in
the non-polar solvent is swelling, therefore, its oil resistance and solvent
resistance is poor, in general, hydrocarbons, halogenated hydrocarbons, Ether,
higher ketones and higher fatty acids have the dissolution of natural rubber,
but its solubility is affected by the degree of plastic refining, and lower
ketones, esters and alcohols on natural rubber is a non-solvent
Our hydraulic rubber hose makes full use of
the properties of natural rubber according to its application.
