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.
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.
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.
