Lanmar #595-5R is a 5 mil polyimide film tape with a silicone adhesive. Polyimide film (amber, transparent) is recognized for exceptional dielectric strength, dimensional stability under heat, and broad chemical resistance — retaining mechanical properties across a wider temperature range than most polymer films.

The silicone adhesive offers clean, residue-free bonding across the full operating range, with reliable peel strength and clean removal after masking operations. Rated from -100 to +500°F. Dielectric strength: 18100V. Insulation Class 180.

Specifications: 5 mil polyimide film / 6 mil total thickness. Break strength: 140 lb/in. Elongation: 40%. Adhesion: 26.5 oz/in.

Common applications include PCB masking during wave soldering and conformal coating, wire and coil insulation wrapping, capacitor wrapping, transformer insulation, and high-temperature electronics protection. Supplied in roll form. Available custom slit to width.
