It also has an adverse effect on the handling of the ground powder.
- Water to be added can be any of pure water, clean water, industrial water and the like.
- Pulverized thermoplastic elastomers tend to cause cohesion due to softening due to heat generated during pulverization.
- thermoplastic elastomers not only thermoplastic elastomers but also crushed materials have a large specific surface area, and generally tend to cause mutual adhesion.
