Latex is a colloidal suspension containing polyisoprene particles, proteins, lipids and water, collected by tapping tree bark and then concentrated and coagulated to form raw rubber.
Raw natural rubber is valued for high elasticity, resilience, tensile strength and damping properties. Its mechanical
Major uses include tyres and inner tubes, industrial belts and hoses, footwear, adhesives, medical gloves, condoms
