DK Glass Fabric is characterized with low dielectric glass. Compared with conventional E glass, DK glass has very low dielectric constant and dissipation factor.
DK glass fabric is woven from new glass formula D glass (low dielectric) fiber yarn with specially dielectric properties. It is widely used for electromagnetic wave, high frequency electronic circuit board. Typically supplied style: 1065, 106, 2116
Features
Neat fabric surface, even thickness
Good resin wet out and easily heat clean
Good for further process, coating and lamination
Available silane, starch sizing
Application
Copper clad lamination; Basic for PTFE, silicone, aluminum foil coating; Adhesive high temperature tape; FRP body reinforcement
