Natural rubber is made of Hevea latex, polymer chemical called polyisoprene. Polyisoprene rubber matrix can also by its monomer polymerization. Natural rubber has many excellent physical properties: the rebound rate of up to 0 -100 ℃ 50%-80%, the elongation is 1000%, the tensile strength of 17-25Mpa pure rubber, vulcanized carbon black reinforced rubber was 25-35Mpa, tensile stress at 500% above 12Mpa, good air tightness, infiltration rolling parameters for 2.969* 10 H2 (s.Pa) and similar to SBR, its shortcoming is not resistant to hydrocarbon oil, not suitable for ultraviolet light, oxygen, ozone. But the poor weather resistance can be improved by special additives.

(one) temperature range

-50 ℃ -70 ℃, (short time of up to 100 DEG C)

(two) hardness range

Shore A40 degrees to 90 degrees

(three) colour

Black color, can also be specified by the client.

(four) application

Natural rubber and is very good, with many glue and use. In the tire industry, natural rubber can be used in the manufacture of tread, sidewall tire, each part, also used in the manufacture of tube. Natural rubber can also produce rubber hose, tape, general mechanical seals, sponge products, surgical products, latex products.
