Development of Halogen Free, Low Loss Copper-Clad Laminates Containing a Novel Phosphonate Oligomer
Aug 24, 2017 | Dr. Lawino Kagumba - FRX Polymers Inc., Yang Zhong Qiang, Huang Tian Hui, You Jiang, Douglas Sober - Shengyi Technology Co., Ltd.
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....
