    • This invention relates to a low dielectric resin varnish composition for laminated printed circuit boards, wherein the resin composition includes (A) Dicyclopentadiene-Phenolic Novolac resin (abbreviated as DCPD-PN); or (B) at least one kind of dicyclopentadiene Phenolic Novolac Epoxy resins(DCPD-PNE, referred to as Resin 1); or (C) a novel Dicyclopentadiene- Dihydrobenzoxazine resin (DCPD-BX, referred to as Resin 2); or the mixture of (B) and (C), and (D) Flame retardant agent, curing agent and accelerating agent solutions.
      Because all of component (A) DCPD-PN, component (B) DCPD-PNE and component (C) DCPD-BX in this resin varnish composition contain a saturated multi-cyclic structure of dicyclopentadiene, the resin varnish shows lower dipole, dielectric constant (Dk), dissipation factor (Df) and moisture absorption; and via adding a brominated or phosphorus flame retardant, the composition exhibits high thermal stability characteristic. The copper clad laminates obtained in accordance with the invention meet not only the demand of low dielectric constant (Dk
    • 对于层叠的印刷电路板本发明concerne未低介电树脂组合物清漆,欧乐树脂组合物包括(A)二环戊二烯苯酚酚醛清漆树脂(缩写为DCPD-PN); 或(B)至少一种二环戊二烯苯酚酚醛清漆环氧树脂的(DCPD-PNE,称为树脂1); 或(C)一种新颖的二氢苯并恶嗪二环戊二烯树脂(DCPD-BX,称为树脂2); 或(B)(C)和(D)阻燃剂,该混合物与固化剂和促进剂的解决方案。 因为所有的DCPD-PN,组分(B)DCPD-PNE和组分(C)DCPD-BX在该树脂清漆组合物内含已饱和二聚环戊二烯的多环结构(A)成分的,该树脂清漆显示出较低的偶极常数介电 (DK),耗散因数(DF)和吸湿; 并通过添加溴化或磷阻燃剂,所述组合物表现出高的热稳定性特征。 在与本发明所述获得的覆铜箔层压板不仅满足低介电常数的需求(DK <4.0 @ 1千兆赫)和低的耗散因数(DF <0.009 @ 1GNz),目标澳大利亚游泳会具有高的热稳定性和低水分吸收特性 ,因此被广泛适用于高性能的电子材料。

    • A phenolic foam is made by foaming and curing a foamable phenolic resin composition that comprises a phenolic resin, a blowing agent, an acid catalyst and an inorganic filler. The blowing agent comprises an aliphatic hydrocarbon containing from 1 to 8 carbon atoms and the inorganic filler is at least one selected from a metal hydroxide, a metal oxide, a metal carbonate and a metal powder. The phenolic foam has a pH of 5 or more. The phenolic foam has a higher pH value compared with conventional phenolic foam and reduces corrosion risk when in contact with metallic materials. The phenolic foam maintains excellent long-term stable thermal insulation performance, low water uptake and fire resistance performance and by using a hydrocarbon blowing agent, does not harm the environment as an ozone depleting or global warming material.
