Foaming glue classification

Foaming glue comes in two types: gun-type and tube-type (commonly known as disposable). Tube-type foaming glue is primarily used for retail applications, meaning it's only suitable for household applications with low-volume leak prevention and plugging. Furthermore, tube-type foaming glue generally isn't very high quality. Most companies don't use tube-type foaming glue for 750ml packaging or high-quality products. Tube-type foaming glue has lower pressure than gun-type foaming glue, which can sometimes cause uneven application and lead to problems like valve failure. Furthermore, the foam cells produced by tube-type foaming glue aren't as fine as those produced by gun-type foaming glue, and its expansion force is relatively greater. Gun-type foaming glue is actually less expensive than tube-type foaming glue.
