Thermoplastic polyimide film: properties and limits
Thermoplastic polyimide film, or TPI film, is a polyimide substrate that melts and flows when heated, so it can be hot pressed, bonded[…]
Flame Retardant Polycarbonate: Transparency and UL94 V-0
Flame retardant polycarbonate hits UL94 V-0 and stays clear when the retardant sits inside the polymer instead of being mixed into it. Sulfonate[…]
Polyamide Formulation Screening: From Weeks to Seconds
Polyamide formulation screening uses machine learning to rank candidate polyamide recipes by predicted performance before anyone mixes a gram of material. A trained[…]
Types of fluoroplastic cables: stranded wire to coax
Fluoroplastic cables are wires and cables that use a fluoropolymer such as PTFE, FEP, PFA, ETFE, or PVDF as insulation, jacket, or dielectric.[…]
6G Materials Race: Which Will Industrialize First?
6G will not reach mass commercial deployment for several years, yet the materials work that decides device performance has already begun. Among the[…]
Polyphenylene Sulfide Structure: One Chain Explains All
Polyphenylene sulfide structure is a strictly alternating chain of para-phenylene rings and sulfide sulfur atoms, and that single arrangement explains nearly every property.[…]
Polycarbonate blend modification: impact, flow, flame
Polycarbonate blend modification is the practice of mixing PC with elastomers, copolymers, fillers, or reactive compatibilizers so that impact strength, solvent resistance, melt[…]
Foamed fluoropolymer insulation: how cables cut signal loss
Foamed fluoropolymer insulation is FEP or PFA extruded as a closed-cell foam around a conductor to cut the dielectric constant without losing heat[…]
Foamed fluoropolymer cable: lower loss, smaller wire
Foamed fluoropolymer cable traps air inside FEP, PFA, or ETFE insulation to cut dielectric constant and loss without losing heat, flame, or chemical[…]
PVDF FEP blend compatibility: what the structure decides
A PVDF FEP blend is not a single-phase alloy. The two resins crystallize on their own and settle into a partially miscible two-phase[…]
