With the continuous development and innovation of the silica gel industry, due to the wide application of silicone rubber products in various industries, there are more and more silicone rubber products in the market. However, there are also some inferior or fake silicone rubber products. How can we judge the quality of silicone rubber products when purchasing silicone rubber products?
1、 Abrasion resistance
Abrasion resistance is required for the production and molding of silicone rubber products. The surface of silicone rubber products can be subject to wear. Generally, good silicone rubber products rarely rub off the surface of products due to external factors, which does not affect the appearance, text and color of performance. The characters on the surface of silica gel products with poor quality are easy to drop.
2、 Elasticity
Silicone products have good elasticity, because the high elasticity mainly comes from the movement of the molecular chain segment of silicone rubber, so when purchasing silicone rubber products, first look at the elasticity of silica gel products to judge the quality.
3、 Tear strength and tensile strength
Silicone products with high tear strength have outstanding resistance to damage, long service life, and are not easy to be disturbed by the external environment. Silicone products with poor tear strength are generally prone to cracks in the tearing process, thus rapidly expanding cracks when stressed and causing damage.
4、 Fatigue resistance
When silicone rubber products are subjected to alternating stress (or strain), the phenomenon that the structure and properties of materials change is called fatigue. With the progress of the fatigue process, the phenomenon that leads to the damage of silicone products is called fatigue damage.
5、 Hardness and elongation stress
An important indicator of the rigidity (stiffness) of rubber materials, both of which are the forces required for silicone products to produce certain deformation.
So when buying silicone products, the most important thing is to first look at the wear resistance, elasticity and tear strength. If it meets the requirements, it indicates that it is a silicone product with good quality. If it is not satisfied, it will be abandoned to avoid financial loss.
