1. Raw material preparation
The main materials of compound rubber products are raw rubber, compounding agent, metal material and fiber material. The raw rubber is the basic material; the compounding agent is the auxiliary material added to improve some properties of the rubber compound; Fiber) is used as the skeleton material of the compound rubber product to enhance the mechanical strength and limit the deformation of the product. In order to make the raw rubber and compounding agent mix evenly with each other, some materials need to be processed, so in the process of raw material preparation, the ingredients are accurately weighed according to the formula.
Our products are Silicone Pet Supplies
2. Plasticizing
Raw rubber is elastic and lacks processing properties (plasticity), so it is not easy to process. In order to improve its plasticity, it is necessary to masticate the raw rubber; in this way, the compounding agent is easily dispersed in the raw rubber during mixing; at the same time, it also helps to improve the permeability of the rubber during the calendering and molding process (penetration fabric) and molding fluidity. The process of degrading the long-chain molecules of raw rubber to form plasticity is called mastication. There are two methods of plasticizing raw rubber: mechanical plasticizing and thermal plasticizing. Mechanical mastication is a process in which the long-chain rubber molecules are degraded and shortened by the mechanical extrusion and friction of the plasticizer at a temperature that is not too high, and transformed from a highly elastic state to a plastic state. Hot plasticizing is to introduce hot compressed air into the raw rubber, under the action of heat and oxygen, the long-chain molecules are degraded and shortened, thereby obtaining plasticity.Our products also include Silicone Bracelets/Wristbands, etc. If necessary, please contact us. After 10 years of growth, we have developed into a well-known professional silicone gift manufacturing enterprise, providing one-stop service from design, development, production to sales.
