how to choose the appropriate silicone foam tubing?
(1) Silicone foam tubing is relatively soft, the elasticity is good, and feels good, you can touch it to try its resilience;
(2) Use scissors or other tools to cut the silicone foam tubing, and then place it for some time to observe its fracture. Placing the fracture is not smooth and slightly curved, if its arc is high, it is high glue content; If it is high-temperature vulcanization, it will be more obvious.
(3) Cut out a section of silicone foam tubing for burning, then observe the smoke is whether pure white, or white, after burning, see if the residue is white or light gray, After burning, for good quality silicone foam tubing, its gas is white, the residue is gray, and tasteless, if you use this method, remember to carry out in the ventilation position, And pay attention to fire safety.
