Among the many silicone products, there are many silicone products are welcomed by everyone, widely used by everyone, among which, silicone foam tube is a more common one, silicone foam tube is made using extrusion process, is the use of silicone as raw materials to reasonably mix with blowing agent, and then high temperature vulcanization and made of soft elastic products, due to the vulcanization, So it creates a lot of small holes inside.
General
silicone foam tube is used for sealing operations,
silicone foam tube also has a nickname called "silicone sponge tube", silicone foam tube is not only resistant to high and low temperatures, but also has good insulation, anti-aging, ozone resistance, general silicone foam tube used in buildings, cars, ship Windows and other sealing, cable wire and other parts and some industrial products are also used.
With the continuous increase in sales of silicone foam tubes on the market, which silicone foam tubes have different quality in the market, then, how do we judge whether the silicone foam tubes are high quality and how to choose the right products?
We can test it through practical action to see whether it is high-quality and good.
1, the general silicone foam tube is relatively soft, and the elasticity is good, feel good, you can touch to try its resilience how;
2, the use of scissors or other tools to cut the silicone foam tube, and then placed for a period of time, to observe its fracture, so that the fracture is not smooth, so that it is slightly curved, if its curvature is relatively high, that is, the amount of glue is higher, if it is high temperature vulcanization, it is more obvious.
3. Burn, cut out a section of silicone foam tube for burning, observe whether the smoke is pure white or basically white, after burning, see whether the residue after burning is white or light gray, good quality silicone foam tube is burned and burned, its gas is white, the residue is gray, and tasteless, if you use this method, remember to carry out in the ventilated position, Pay attention to fire safety.
In general, the poor quality silicone foam pipe not only looks bad, but also poor resilience, easy to crack, strength is not good, and the smell is pungent; If it is a good quality silicone foam tube, then it not only looks good, feel good, relatively light, good resilience, relatively stable, no odor.
