I. Viscosity. Professional term explanation: The volume characteristics of liquid, quasi-liquid or quasi-solid substances to flow, that is, the internal friction or internal resistance between molecules when flowing under the action of an external force. Generally, viscosity is proportional to hardness.

Ii. Hardness. The ability of a material to resist the indentation of a hard object on its surface locally is called hardness. Silicone colorful beaded bracelets custom Shore hardness ranges from 10 to 80, which gives designers ample freedom to choose the hardness needed for a particular function. Various intermediate hardness values can be obtained by mixing polymer substrates, fillers and additives in different proportions. Similarly, the time and temperature of heating and curing can also change hardness without damaging other physical properties.

Iii. Tensile Strength. Tensile strength refers to the force required to tear a rubber material sample within each range unit. The tensile strength range of thermally vulcanized solid silicone rubber is 4.0-12.5MPa, and that of fluorosilicone rubber is 8.7-12.1 MPa. The tensile strength of liquid silicone rubber ranges from 3.6 mpa to 11.0 mpa.

Iv. Tear Strength. The resistance to the notch or the expansion of the notch when force is applied to a sample with a notch. Hot vulcanized solid silicone colorful beaded bracelets custom will not tear even when cut and placed under high torsional stress. The tear strength range of heat-vulcanized solid silicone rubber is 9-55 kN/m. The tear strength range of fluorosilicone rubber is 17.5-46.4 kN/m. The tear strength range of liquid silicone rubber is 11.5-52kn/m.

V. Elongation. It usually refers to "ultimate elongation at break" or the percentage increase in length relative to the original when the sample breaks. Generally speaking, the elongation range of heat-vulcanized solid silicone rubber is 90-1120%. The general elongation of fluorosilicone rubber ranges from 159% to 699%. The elongation of general liquid silicone rubber is between 220 and 900%. Different processing methods and the selection of hardeners can greatly change its elongation. The elongation of silicone rubber is closely related to temperature.

Vi. Operating Time. The operation time is calculated from the moment when the vulcanizing agent is added to the colloid. In fact, there is no complete boundary between this operation time and the subsequent vulcanization time. When the vulcanizing agent was added, the gel had already been vulcanized. This operation time means that the 30-minute vulcanization reaction of the product should not affect the quality of the finished product. So the more time is saved in the product operation process, the better the finished product will be.

Vii. Curing Time. In some places, it is said to be the curing time. That is to say, after such a long time, the vulcanization reaction of silicone rubber has basically come to an end. This is basically over. That is to say, the product is ready for use, but in fact, a small part of the curing reaction has not yet ended. So SILICONE colorful beaded bracelets custom products usually have to be left idle for a while before they can be put into use.
