Release film NITOFLON™ No.900UL

insulationfluoropolymerPTFE

Product overview
Fluoroplastic film made of PTFE for industrial applications requiring heat‑resistant electrical insulation, low friction and reliable mold release. Continuous recommended service range −100°C to 260°C; UL94 flame retardancy certified (E52859).

Features

• Wide thickness lineup from 0.03 to 1.5 mm.
• Excellent chemical resistance to most acids, alkalis and organic solvents.
• High dielectric strength and low dielectric loss for electrical insulation.
• Continuous use recommended from −100°C to 260°C; short‑term use at higher temperatures possible.
• Very low kinetic friction among solid materials.
• Adhesives and residues do not adhere easily—facilitates mold release.
• Non‑hygroscopic and minimal degradation from UV exposure.
• UL94 flame retardancy certified (VTM‑0 for 0.03–0.24 mm / V‑0 for >0.25 mm, registration no. E52859).

Structure
Single‑layer fluoroplastic (PTFE) film construction (see product page for structure diagram).

Applications

• Improve releasability in molding processes.
• Mold release and cushioning for thermal compression bonding such as ACF and TCB.
• Heat‑resistant electrical insulation for motor and transformer coils.
