The PEI leader tape is made of a polyetherimide resin produced by Mitsubishi Technologies of Japan and processed by a precision die-cutting process. This polymer plastic film has excellent mechanical properties, and its glass transition temperature is very high in thermoplastic resins, and it has a characteristic of small dimensional change when heated to 210 °C. It has excellent chemical resistance to aliphatic hydrocarbons, acids and dilute bases, and is also extremely resistant to polar solvents.
Product Size: At present, this product specification: 35, 35SW, 48, 48SW, 70, product thickness: 75μm, because of its good temperature resistance, it is often used for strip traction in high temperature environment.
