Why do silicone products have insufficient elasticity in the process?

Some undesirable phenomena will occur if silicone products are not noticed in the molding process. This is a common problem for silicone rubber manufacturers. Here is a detailed introduction to the causes?

For example, silicone products have poor elasticity. Some frequently used silicone parts have certain requirements on tensile toughness, and the products mainly need their tensile toughness to maintain. Therefore, in some manufacturing industries, once the silicone material used in the mechanical industry has insufficient tension and rebound damping failure, other properties of the product will be useless. Therefore, the operation of the personnel, the modulation of the machine and the coordination of the raw materials in the molding process are the keys to the toughness and poor quality of the product.

Common silica gel has some problems with raw materials

For example, the service life is not up to the standard, the toughness is poor, and the rebound is insufficient. In addition, the addition of too much silicone oil and white carbon black in the silica gel raw material leads to the performance confusion of the product, the silicon atoms in the silicone resin are destroyed, the flexibility is reduced, and the viscosity and fluidity are not good, which leads to the reduction of the tensile strength of the product after high-temperature molding. The product will not be reflected after the completion of production, but after a period of use under various environmental conflicts, the product will gradually deform, and the rebound rate will decline, The product is sticky.

In the silicone product molding process, the debugging and coordination of the machine have a certain impact. Sometimes during the vulcanization process, in order to improve the output and increase the production efficiency, the staff will reduce the vulcanization time and the product will appear soft. When increasing the output, the temperature must be increased to reach a certain balance rate on the premise of reducing the time, otherwise the product will appear various undesirable phenomena, However, if the production time is too long, the product will also tear if it is too brittle and stretched. It is recommended to properly control the product time and curing temperature during the production process.

In a word, in the production process, except for the machine, raw materials, human beings, environment and other factors, the toughness of silicone products will not have quality problems. Therefore, the silicone product manufacturers have controlled these factors in the production process, and the product quality will basically not have problems.
