What are the Types of DTF Powders?
Similar to their granularity, DTF powders come in different types. Each type offers special qualities ideal for a specific printing application. Let’s look at the most common DTF powder types below.
TPU:
TPU stands for Thermoplastic Polyurethane. As mentioned before, polyurethane is comprised of most white DTF powders. Hence, TPU is also the market’s most widely used adhesive powder type.
The reason for its popularity is its guaranteed elastic and durable design finish. An elastic finish is necessary to prevent the transferred design from cracking. TPU adhesives allow the prints to move with the fabric. This flexibility prevents the prints from splitting, making the final product long-lasting.
PES:
Polyethylene Sulfide (PES) DTF powder is a more rigid, less elastic type than TPU. The rigidity of this powder makes for a more lasting print and improved wear resistance. If you are a fan of polyester garments, this would be your DTF powder of choice. PES powder is often applied when printing on polyester fabrics. Such hot-melt adhesives are also based on polyester resin.
PA (polyamide):
Polyamides breed a balance between elasticity and strength. PA transfer powders borrow TPU’s elastic properties and PES’s rigidity. They are made from synthetic polymers and are often referred to as nylon. With excellent stretchability and durability, PA commands versatile application.
Although less popular than TPU, PA powders are ideal for applying to prints requiring better resistance to wear.
