Polyimide Masking Discs are primarily used in circuit board production, wave soldering, and other applications where static charge is a concern. They are made of 1 mil thick polyimide film backed by 1.5 mil silicone adhesive with electro-static dissipative (ESD) properties to reduce the static charge. The silicone adhesive leaves no residue. Total thickness of this product is 2.5 mil. They can withstand temperatures of up to 260 degrees C (500 degrees F). Color is amber.
