Organic silicone - the function of an object is nature, it must have to control it, understand it, you should know the characteristics of it, pad printing silicon good physical properties, there is so much good, can be applied to the different needs of different occasions.

A, viscosity

In general, the viscosity of liquid silica gel is proportional to the hardness, so the viscosity of silica gel required by different requirements is different.

Second, the hardness

Silicone rubber has a range of 10 to 80, which gives the designer the freedom to choose the required hardness to best achieve a specific function. A variety of intermediate hardness values can be achieved by mixing the different ratios of polymer base materials, fillers and additives. Similarly, the time and temperature of heating can also change the hardness without destroying other physical characteristics.

3. Tensile strength.

The tensile strength of the hot and sulfur solid silicone rubber is between 4.0-12.5mpa. Fluorosilicone rubber tensile strength range is between 8.7-12.1MPa. The tensile strength of liquid silicone rubber is between 3.6 and 11.0MPa.

Iv. Tear strength.

Even after the incision is placed under extremely high torsion stress, the hot and sulfur-type solid silicone rubber can not be torn apart. The tear strength range of hot and sulfur solid silicone rubber is between 9 and 55 kN/m. The tear strength range of fluorosilicone rubber is between 17.5-46.4 kN/m. Liquid silicone rubber tear strength range is between 11.5-52 kN/m.

5. Elongation.

The general elongation range of the hot and sulfur solid silicone rubber ranges from 90 to 1120%. Fluorosilicone has a general elongation rate between 159 and 699%. The elongation of liquid silicone rubber is between 220 and 900%. Different processing methods and selection of hardener can change the elongation greatly. The elongation of silicone rubber has a lot to do with temperature.

6. Control time.

Behind the manipulation time and the boundaries of the curing time is not fully, the colloid from join the vulcanizing agent that moment start already for curing reaction, the manipulation of time is the product of 30 minutes vulcanization reaction can not affect the quality of the finished product. So the more you save time in the process of product manipulation, the better it will be for the finished product.

7. Curing time.

That is to say, the vulcanization reaction of silica gel over such a long time is basically over. This basically ends and that means the product is already available, but there's actually a very small set of consolidation reactions that are not over yet. So the products made from silicone rubber, like mold silicone, are usually put into use for a period of time.
