Hardness scale silicon tubing

Hardness scale silicon tubing

Our silicone tubing is used for a variety of purposes and we can adapt it to applications in a number of industries, ranging from military and automotive, all the way to the food, pharmaceutical industry and medicine. All you need to do is contact us and provide us with information on what kind of silicone tubing you need. We will make it according to your requirements on dimensions, color, design, transparency and other important physical properties. One of the very important properties of silicone tubing that we take special care of during production is hardness.

The hardness scale of silicone tubing allows us to determine how hard the silicone tubing is, and therefore whether it meets the stated requirements and specifications. In order for silicone tubing to be optimal for final application, it is necessary to have an appropriate value on the hardness scale of silicone tubing.

The hardness of silicone tubing implies a parameter that shows how much silicone tubing is resistant to pressure and the occurrence of deformations under the influence of mechanical force. In practice, this means that the value that this material shows on the hardness scale silicone tubing indicates whether the material will deform easily if something is pressed against its surface.

Depending on the material, there are different methods and techniques that allow to determine the hardness. When it comes to silicone, hardness is tested using a test that uses a device known as a durometer. During this test, it is examined how deep the cone-shaped object can penetrate the surface of the silicone. The softer it is, the penetration depth of the durometer will be greater and the value on the hardness scale of the silicone tubing is small. When the material is very hard and resistant to deformation, the cone cannot penetrate deep into the surface, so the value on the scale is very large.
