3L rubber from Vietnam refers to the standard rubber produced in Vietnam, with a model of 3L and a weight of 33.33kg/block. Its main components include rubber hydrocarbons, proteins, water, resin acids, sugars, and inorganic salts. Vietnam 3L rubber has fewer impurities, and the smaller the value, the less impurities there are. It is mainly used for shoe soles, tires, conveyor belts, V-belts, rubber rollers, and sealing products.
physical characteristics:
Vietnamese 3L rubber has excellent elasticity and tensile strength, good tear resistance and electrical insulation, as well as excellent wear resistance and drought resistance. It has good processability and is easy to bond with other materials. However, its oxygen and ozone resistance is poor, and it is prone to aging and deterioration; Low resistance to oil and acid alkali corrosion; The heat resistance is not high, and the operating temperature range is about -60 ºC to+80 ºC
The technical parameters of Vietnamese rubber 3L mainly include the following aspects:
Physical characteristics:
Density: The density of 3L Vietnamese rubber is usually between 0.90-0.92 g/cm ³.
Hardness: Moderate hardness, neither too hard nor too soft, suitable for various application needs.
Mechanical properties:
Tensile strength: It has good tensile properties and can withstand large tensile forces without easily breaking.
Tear strength: It has high tear strength and can resist tearing and damage.
Wear resistance: It has good wear resistance and is suitable for applications that require high wear resistance.
Cold resistance: It has good cold resistance and can be used in low temperature environments.
