Silicone Rubber Industries

Rubber is one of the most versatile materials for industrial uses. From darily shoe sole to natural rubber car tires, it is widely used in every aspect in our life. However,the use the rubber material ,it need to process in 4 step ,including Mastication , mixing, shaping, and vulcanizing. 

(1) Mastication. In this process ,it is usually finished by one huge machine called banbury,Rubber mixers  or dispersion kneader machine ,it would add some additives and chemicals to improve its tensile strength and characteristics,so that change rubber compounds.For this process ,our banbury are available from 35litre to 150 liter.

(2) Mixing, Usually ,it is carried out immediately after mastication , and similar to mastication, this process also add some additives when mix the rubber material.  This process need two roller mills or open mixing mill ,which is a machine used to process natural rubber into various compounds. It has two horizontally opposed stainless steel rolls rotate in opposite directions towards each other at different speeds ,so that mix the rubber to create the rubber compounds.

(3) Shaping

The shaping of the mixture into the desired form have many ways .Like coating, extrusion, casting, calendering, and molding. It depends on the final product, you can adopt the best shaping techniques.

 For example extrusion are used to produce long continuous products such as tubing, tire treads, and wire coverings. While roller calenders are used to make wide sheet.

4. Vulcanization

Vulcanization is also called curing,which is one chemical process for rubber, natural or synthetic. Curing is heated by steam or electricity with sulfur, accelerator, and activator at some temperatures and pressure. Through this process ,the rubber material would improves its feature obviously ,its elasticity, resilience, tensile strength, viscosity, hardness, and weather resistance would increase accordingly.
