How much do you know about the hardness, tensile strength and tear strength of china silicone gel price? Let's take a look at it briefly!
1. Hardness
The ability of a material to locally resist hard objects pressed into its surface is called hardness. Silicone rubber has a Shore hardness range of 10 to 80, which gives designers full freedom to choose the required hardness to achieve specific functions. Various intermediate hardness values can be achieved by mixing polymer substrates, fillers and additives in different proportions. Similarly, the time and temperature of heating and curing can also change the hardness without destroying other physical characteristics.
2. Tensile strength
Tensile strength refers to the force required in each range unit to cause a piece of rubber material sample to tear. The tensile strength of thermally vulcanized solid silicone rubber is between 4.0-12.5MPa. The tensile strength of fluorosilicone rubber is between 8.7-12.1MPa. The tensile strength of liquid silicone rubber is in the range of 3.6-11.0MPa.
3. Tear strength
The resistance that hinders the enlargement of the cut or score when force is applied to the cut sample. Even if it is placed under extremely high torsional stress after cutting, the thermally vulcanized solid silicone rubber can not be torn. The tear strength range of hot-vulcanized solid silicone rubber is between 9-55 kN/m. The tear strength range of fluorosilicone rubber is between 17.5-46.4 kN/m. The tear strength of liquid silicone rubber ranges from 11.5-52 kN/m.
The above is about the hardness, tensile strength and tear strength of china silicone gel price.
