The hot material of the year for film spraying, electrostatic spray, and 3D printing is likely to be polymer resins that have high thermal stability, good chemical resistance, and good bonding properties. Some examples of such materials include polypropylene (PP), polyethylene terephthalate (PET), and polyamide (PA). These polymers are widely used in various industries for production of films, packaging, electronics, and other applications. The 42 micron size of Ultem PEI MILLED POWDER can make it suitable for use in electronic and optoelectronic applications, where high dielectric constant and low loss tangent are required. Additionally, its high melting point can help maintain the shape of objects during printing and ensure accurate layering. Overall, Ultem PEI MILLED.powder is an excellent choice as a hot material for these industries due to its versatility and performance characteristics.
