Polyonics introduces the XF-604, a 2 mil white polyester, halogen free label material designed and recognized by Underwriters Laboratories to meet the VTM-1 level of flame retardants per the UL94 standard. The addition of the XF-604 to the FLAMEGARDTM product family provides customers with a lower cost alternative to the XF-603 (polyimide) while still exhibiting flame retardant properties.
The Fire Problem The Flame ProblemThe ever-increasing and widespread use of electronic devices, such as laptops, tablets, personal digital assistants (PDA’s) and smart phones is requiring longer and longer battery life. The batteries become increas

Flame retardants have been around since the Egyptians and Romans used alum to reduce the flammability of wood. Brominated flame retardants (BFRs) first experienced use after World War II as the substitution of wood and metal for plastics and foams resulted in materials that were much more flammable. The widespread use of BFRs initiated in the 1970s with the explosion of electronics and electrical equipment and housings. For the US market, all of these products must conform to the UL 94 flammability testing specifications. In fact, the most common printed circuit board (PCB) in the electronics industry, FR-4, is defined by its structure (glass fiber in an epoxy matrix) and its compliance to UL 94 V0 standard.

With the rapid development of the information industry, increasing attention is being paid to the dielectric performance of base materials including copper-clad laminates (CCL) and prepregs. In addition to the increasingly high performance requirements of CCL's, the present global attention to less toxic products is leading to an increase in the use of halogen-free flame retardants in electronics. (...) This paper introduces a new phosphonate oligomer which can be used as a reactive flame retardant in epoxy based resin systems. Suitable conditions for the complete reaction between the phosphonate oligomer and epoxy resin are described and the resulting halogen-free laminates with improved properties such as low Df, low coefficient of thermal expansion (CTE), high peel strength, and good toughness are presented.
