TPU 80-100mic White 1KG Digital Transfer Hot Melt Adhesive Pretreat Powder for Ep L1800 Printer

How can you distinguish the quality of hot melt powder? Here are some tips:

1. Check the color, transparency, and whiteness. The higher the better, indicating better purity. If it's yellowing gray, it may be the same furnace powder or mixed powder, which can lead to a poor feel, easy to pull off, and air holes.

2. Check the surface flatness after drying. Better flatness indicates better purity and tensile strength.

3. The stickier the powder, the worse the quality. It may be damp or have a lot of miscellaneous powder. If so, it can be returned to the oven.

4. When pulling and rubbing, observe the rebound after heat press. Faster rebound indicates higher purity.
