Additive Concentrates for Laser Marking Wire Jackets and Cable Insulation
AGC’s Fluon LaserWrite fluoropolymer-based concentrates can be used with any melt processable resin system.
Three new fluoropolymer-based additive concentrates for laser marking on wire & cable jackets and insulation have been developed by AGC Chemicals, Exton, Penn. Available based on ETFE, FEP and PFA, the new Fluon+ LaserWrite concentrates are said to mix well into existing resin and color concentrate formulations and can be used with any melt processable resin system.
The three grades have been shown to be easy to process on conventional thermoplastic methods such as melt extrusion. AGC can also produce these concentrates as ready-to-use compounds, and custom-compounds, upon request. The company notes that laser marking has proven to be a fast, efficient method of permanently imprinting product information on cable jackets and wire insulation, with little risk of damaging the interior properties of the wire or cable or having laser marks rub off as when applied by the inkjet process.
Newer specialty slip masterbatches go beyond traditional capabilities to provide greater thermal stability, reliability, and ability to hold COF steady during laminating.
Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.
To properly understand the differences in performance between PET and PBT we need to compare apples to apples—the semi-crystalline forms of each polymer.
