PEI Film

Quality characteristics

Dexnyl© PEI film is a thermoplastic film characterized by its excellent thermal performance with a continuous use at higher temperatures. The film can maintain mechanical strength and stiffness with low thermal expansion. These films offer high heat resistance, coupled with high mechanical strength, stiffness, UV stability, and broad chemical resistance. This combination of properties proves the ability of this film to be used for a wide variety of demanding new design concepts. The PEI films has struck the 3D printing world as a high-performance material for 3D printing beds. PEI film enables 3D printing enthusiasts to produce smooth prints and surface along with an excellent finish and highly reduced adhesion problems.
