How to distinguish the quality of silicone foam strip?
2024-09-11
1. The elasticity of foaming silica gel strip
You can use your hands to stretch and feel the resilience of the silicone foam strip.
2. The smell of foaming silicone strip
If it is a silicone foam strip produced with high-quality silicone raw materials, the smell is usually only sour or the taste is not obvious.
3. Cross section of foamed silicone strip
Cut the silicone foam strip with scissors, observe carefully and leave it for a period of time. The cut surface forms a curve, but it is not completely flat. The higher the arc, the higher the gel content of the product, especially the finished product after high temperature vulcanization.
4. From the observation of burning smoke to see the quality of foaming silica gel strip
You can cut off a piece of foam strip, clamp it with tweezers or scissors, light it with a lighter or match, observe whether the smoke released after burning is pure white or mostly white, and then observe whether the ashes after burning are white or light gray. The ash produced by the combustion smoke of the high-quality silicone foam strip is white or gray, and there is no obvious pungent smell.
