Description
KTPU-25 TPU Hot-Melt Powder
KTPU-25 is a TPU hot-melt powder designed for heat transfer applications. The supplied materials show bagged powder, finished apparel graphics, and powder feature information for the model.
The TDS lists a 95-110°C melting range, 1.05 g/cm³ density, 20-35 g/10min melt index, 70A hardness, and 100-200μm recommended particle size. The recommended pressing conditions are 120-140°C, 10-15 seconds, and 1.0-3.0 mpa. Confirm the final process with the target film, ink, textile, and equipment before production.
Machine Structure
KTPU-25 is a consumable powder rather than a printing machine. It is made from thermoplastic polyurethane resin and is intended to work with heat transfer workflows. The supplied main image shows the powder itself together with finished apparel graphics, which helps present the product's practical use direction.
This model is developed to solve release issues and lettering loss seen in some quick-peel printing films. It is suitable for transfer work that needs flexibility, softness, and stable adhesion.
