With the growing prosperity of the silicone products industry, the silicone products industry has become a widely used product, such as industrial fields, daily necessities, medical care, cultural and sports activities, etc. Because of the rapid development of the silicone products industry, the market demand for silicone products is also increasing increase, making the silicone products industry more prosperous.


Among the many silicone products, there are many silicone products that are welcomed by everyone and widely used by everyone. Among them, silicone foam tube is the more common one. Silicone foam tube is made by extrusion process. It is a soft and elastic product made of silica gel as a raw material to be properly mixed with a foaming agent, and then vulcanized at a high temperature. Due to the vulcanization, there will be many small holes inside it.


Generally, silicone foam tubes are used for sealing operations. Silicone foam tubes also have a nickname called "silicone sponge tubes". Silicone foam tubes are not only resistant to high and low temperatures, but also have good insulation, aging resistance, Ozone resistance. Generally, silicone foam tubes are used in the sealing of buildings, cars, and ship windows, as well as parts such as cables and wires, as well as some industrial products.

As the sales and sales of silicone foam tubes in the market continue to rise, the quality of silicone foam tubes on the market varies. So, how do we judge whether the silicone foam tubes are of high quality and how to choose the right product? We can test it through actual actions to see whether it is high-quality and good.

1. Generally, silicone foam tubes are relatively soft, and have good elasticity. They feel good to the touch. You can try their resilience by touching them;

2. Use scissors or other tools to cut the silicone foam tube, and then after a period of time, observe its fracture, make the fracture uneven, and let it bend slightly. If the arc is relatively high, it means that the glue content is high , if it is vulcanized at high temperature, it will be more obvious.
3. Carry out burning, cut out a section of silicone foam tube for burning, observe whether the smoke coming out is pure white or basically white, after burning, check whether the residue after burning is white or light gray, good quality silicone After the foam tube is burned and burned, its gas is white, the residue is gray, and tasteless. If you use this method, remember to do it in a ventilated location and pay attention to fire safety.

In summary, poor-quality silicone foam tubes not only have a poor appearance, but also have poor resilience, are easy to crack, have poor strength, and have a pungent smell; if it is a good-quality silicone foam tube, it not only looks good , feels good, is relatively light, has good resilience, is relatively stable, and has no peculiar smell.
