<\/p>\nNatural rubber is a natural polymer extracted from the latex of the Hevea brasiliensis tree. It is made into an elastic solid through processes such as coagulation and drying. Its main component is cis-1,4-polyisoprene (accounting for 91% to 94%), with the rest being non-rubber substances such as proteins and fatty acids.<\/p>\n
<\/p>\n
Core Characteristics:<\/p>\n
Physical Properties:<\/p>\n
(1) High elasticity and wear resistance: The tensile strength is high (16.7 – 34.3 MPa), the elongation rate can reach 650% – 900%, and the recovery elasticity is excellent (70% – 95%)<\/p>\n
(2) Temperature adaptability: Long-term working temperature range: -55\u2103 to +70\u2103. Short-term tolerance: up to 100\u2103. Low-temperature brittleness point: approximately -50\u2103.<\/p>\n
(3) Electrical insulation: Excellent insulation performance, suitable for wires and cables<\/p>\n
Chemical Weaknesses:<\/p>\n
(1) Poor oil resistance: Easily swollen in mineral oil and gasoline (swelling rate: 80% – 300%)<\/p>\n
(2) Poor resistance to aging: Easily affected by ozone, ultraviolet rays and high temperatures, and requires the addition of anti-aging agents.<\/p>\n
(3) Limited resistance to acids and alkalis: Weak acids can be tolerated, but strong acids (such as hydrochloric acid and nitric acid) are highly corrosive.<\/p>\n
Main applications:<\/p>\n
(1) Tires (accounting for over 70%), rubber hoses, conveyor belts, shock absorbers, and other dynamic load components<\/p>\n
(2) Rubber shoes, medical gloves (requiring modification to enhance weather resistance)<\/p>\n
