Detailed introduction to pure crude raw rubber:
. Rubber, natural or synthetic substance characterized by elasticity, water repellent, and electrical resistance. Natural rubber is obtained from the milky white fluid called latex, found in many plants; synthetic rubbers are produced from unsaturated hydrocarbons. Pure crude rubber is a white or colorless hydrocarbon. The simplest unit of rubber is isoprene, which has the chemical formula C5H8. At the temperature of liquid air, which is about -195° C (about -319° F), crude rubber is a hard, transparent solid; from 0° to 10° C (32° to 50° F) it is brittle and opaque, and above 20° C (68° F) it becomes soft, resilient, and translucent. When rubber is mechanically kneaded, or is heated above 50° C (122° F), it becomes plastic and sticky; above 200° C (392° F) it decomposes. Crude rubber is insoluble in water, alkali, and weak acid; it is soluble in benzene, gasoline, chlorinated hydrocarbons, and carbon disulphide. It is oxidized readily by chemical.waiting for your response.thanksPure crude rubber from rubber tree is available in large quantity,Interested buyers should contact us.
