Ultrasonic thickness gauge measures the thickness of silicone rubber materials

Silicone rubber is a polymer material composed of alternating silicon and oxygen atoms in the main chain, which has various excellent properties and wide application.

Properties of silicone rubber

Silicone rubber has high air permeability, with the highest oxygen permeability among synthetic polymers; Good chemical stability, acid and alkali resistance, corrosion resistance; The electrical insulation performance is strong, with low moisture absorption, and the performance changes little at high frequency or damp.

Uses of silicone rubber

Silicone rubber is often used as a packaging material for electronic components in the field of electronics; In the medical field, commonly used as medical materials; In the automotive industry, silicone rubber is used to manufacture components such as engines, braking systems, and transmission systems; Due to its high and low temperature resistance and chemical corrosion resistance, it is applied in the power, aviation, and aerospace industries; In addition, silicone rubber can also be used in industries such as building materials, chemicals, and food.

Sample Worpiece

We received customer sample workpiece, insulated silicone rubber sheathed power cables. It has the characteristics of heat and cold resistance, corrosive gas resistance, water proof and so on. The cable structure is soft, the electrical performance is stable in high temperature and cold environment, and the anti-aging performance is outstanding, it’s service life is long, widely used in metallurgy, electric power, petrochemical, electronics, automobile manufacturing and other industries.

The main function of the silicone rubber cable protective layer is to protect the cable from mechanical damage and damage by various environmental factors, such as water, sunlight, organisms, fire, etc., during the laying and operation of the cable to maintain long-term stable electrical performance. Therefore, the quality of the insulating silicone rubber cable protective layer is directly related to the service life of the cable.

Therefore, using an ultrasonic thickness gauge to measure whether the thickness of the cable sheath is up to standard and uniform is the main means and method for controlling product quality.

Measurement and Analysis

First of all, when measuring, multiple factors such as the thickness, material, and geometric shape of the workpiece being measured should be considered, and suitable instruments and probes should be selected. This is a crucial first step in the detection process.

The sound velocity of general silicone is about 900-1500m/s, and the good sound transmission performance frequency range is 2-3 MHz.

Test Result

Using Yushi PM5 Gen2 ultrasonic thickness gauge with a 2.25M probe for testing, the echo is clear and the measurement value is stable.
