Hot Melt Adhesive For Pearl Cotton 1. Pearl cotton is divided into porous type and ordinary type. For the porous type, it is necessary to pay attention to the fact that there can be no drawing during the viscose process, so it is necessary to choose the pearl cotton hot melt adhesive particles that are not drawn.
5. The pearl cotton is bonded with other materials, such as honeycomb cardboard. At this time, it is necessary to consider whether it can stick to the two materials of pearl cotton and cardboard, and select the appropriate hot-melt glue particles according to the actual requirements.

Blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to A Line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.
2. Features of blind flanges: Some important features of blind flanges are as follows:
Blind flanges are sometimes supplied with NPT fittings which allow pressure test connections to be fitted.
They are used to blank off the ends of pipe.
They are also used to blank off the ends of valves and pressure vessel opening.
Considering factors like internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed of all types of flanges.
Since the maximum stresses in a blind flange are bending stresses at the center, they can safely be allowed to be higher than in other types of flanges.
Blind flanges are made to fit standard pipes in all sizes.

2. Pearl cotton is divided into white and colored. Generally, white pearl cotton is common, and colored pearl cotton requires transparent or consistent color hot melt adhesive particles for the color of hot melt adhesive.
3. Pearl cotton is divided into large and small pieces. The bonding process of large pieces of EPE takes a long time, and it is necessary to choose hot melt adhesive particles with a slower curing speed. The bonding process of small pieces of pearl cotton will be faster, and it is necessary to choose hot melt adhesive particles with fast curing speed.
4. There are different density in pearl cotton foam. The pearl cotton with a relatively high surface density needs to choose a more viscous pearl cotton rubber particle, because the pearl cotton with a high surface density is relatively less sticky.
