SRB003 Adhesive sheet material

SRB003 bonding sheet material is a thermoplastic copolymer of polytrifluorovinyl chloride (CTFE). It is often used in microwave ribbon line and other multilayer circuit PTFE substrate material bonding, can also be used in other structures and electrical components and dielectric material bonding. The thickness of SRB003 bonding sheet material is 0.038mm and 0.076mm, and the bonding sheet film is supplied in 457mm reel form and sheet form.
