The rubber industry involves a variety of terminology, of which fresh latex refers to the white emulsion cut directly from the rubber tree.

Standard rubber is classified as granular rubber in sizes 5, 10, 20 and 50, of which Standard Rubber Category 5 (SCR5) consists of two types: latex standardised rubber and condensed standardised rubber.

Latex standard rubber is produced through direct solidification of latex granulation and drying, while gel standard rubber is made from air-dried film through creping, granulation and drying.

Menni viscosity is an indicator of the torque required to rotate the rotor in the rubber mould cavity under specific conditions.

Dry rubber content indicates the number of grams obtained by drying 100g of latex after acid coagulation.

Rubber is divided into raw rubber, which is raw rubber, and vulcanised rubber, which is cross-linked rubber.

Matching agent is a chemical added to the raw rubber to improve the performance of rubber products.

Synthetic rubber is made from monomers by polymerisation reaction to make highly elastic polymers.

Reclaimed rubber is used rubber products and vulcanised rubber waste materials after processing.

Vulcanising agents cause cross-linking of rubber, while scorching is a premature vulcanisation phenomenon.

Reinforcing agents and fillers improve the physical properties of rubber and reduce costs, respectively.

Softeners or plasticisers increase the plasticity of rubber, while rubber ageing is the process of gradual loss of rubber properties.

Antioxidants delay or inhibit rubber aging, divided into chemical and physical antioxidants.

Frost spraying and sulphur spraying refer to the phenomenon of sulphur and other cooperating agents spraying out and sulphur yellow precipitating into crystals respectively.

Plasticising is the process of converting raw rubber into plastic rubber, which is able to maintain deformation after being subjected to force.

Mixing is the matching agent into the rubber to make the process of mixing rubber, coating is the rubber paste coated on the surface of the fabric.

Calendering is the mixing of rubber into film or tape semi-finished process, fixed tensile stress, maximum tensile stress and elongation at break reflect the vulcanised rubber deformation resistance, resistance to damage and deformation characteristics.

Tear strength characterises the ability of the material to resist crack expansion, rubber hardness and abrasion respectively indicate the ability of rubber to resist deformation and surface wear.

Rubber density refers to the mass of rubber per unit volume

Fatigue resistance is the structural and performance changes of rubber under cyclical external forces.
Ripening refers to the process of stopping the rubber gel block, and the ripening time is the time experienced from the solidification of latex to dehydration.

Shore A Hardness: Hardness refers to the ability of rubber to resist the intrusion of external pressure and is used to indicate the degree of hardness of rubber.

Tensile Strength: Tensile strength, also known as tensile strength or tensile strength, refers to the force per unit area when the rubber is torn, expressed in Mpa.

Tearing elongation: referred to as elongation, is the rubber is torn, the length of the stretching increase and the original length of the ratio, expressed as a percentage (%).

Resilience: also known as resilience, or impact elasticity, elasticity, is also an important performance indicator to measure the elasticity of rubber.

Tear permanent deformation: referred to as permanent deformation, is also an important indicator of rubber elasticity.

Fixed tensile strength: also known as fixed tensile strength. It refers to the force required per unit area when the rubber elongates to a certain length, i.e., to 100%, 200%, 300%, 500%.

Tear resistance: rubber products in use, if there is a crack, will be more and more tearing and lead to the final scrap. Therefore, tear resistance is also a very important mechanical property index for rubber products.

Adhesion and adhesion strength: rubber products between the two bonding surface (such as rubber and cloth or cloth and cloth) when the separation of the force required is called adhesion.

Abrasion: also known as a certain abrasion reduction, is a measure of rubber material wear resistance of the main quality indicators, it is measured and expressed in many ways.

Brittleness temperature and glass transition temperature: this is the determination of rubber cold resistance quality indicators. Rubber in the Celsius below zero degrees will begin to harden, the elasticity is greatly reduced; as the temperature continues to fall, gradually hardened to the complete loss of elasticity, like glass, brittle and hard, a knock on the broken, this temperature is called the glass transition temperature, is the minimum use of rubber temperature.

Cracking temperature: After the heat temperature of rubber reaches a certain degree, the gel will be cracked, and this temperature is called cracking temperature.

Resistance to expansion: Some rubber products are often in contact with acid, alkali, oil and other substances in use, and such substances make the rubber products expand, the surface becomes sticky, and finally the products are scrapped. Rubber products to resist acid, alkali, oil and other effects of performance is called anti-expansion.

Aging coefficient: aging coefficient is a measure of rubber aging resistance of a performance indicator, it is at a certain temperature, after a certain period of time to the rubber aging, aging and aging with the physical and mechanical properties (tensile strength or tensile strength and elongation of the product) of the ratio to indicate.
