Huntsman Advanced Materials has introduced two halogen-free laminating resins that comply with regulatory requirements for PCB manufacturing.
 
AZYRAL one- and two-component laminating systems combine versatile processing capabilities with good electrical characteristics and physical properties. Multilayer PCBs and other electrical components fabricated with the materials can withstand exposure to tough operating conditions.
 
Halogen-free AZYRAL XU8282-1 resin is RoHS compliant for Pb-free soldering operations.  This and two-component AZYRAL XTW8291/XTW8293 laminating systems feature easy-to-process, low viscosities for use with FR4 processing. Are nondicy-curing products, meet UL 94 V-O specifications.
 
Said to produce PCBs with a low dielectric constant, low dissipation factor, good surface resistivity and good volume resistivity.
 
Resins are high-temperature resistant materials with low moisture absorption, good thermal stability with glass transition temperatures from 320-482ºF, low coefficient of thermal expansion  and low shrinkage.
