Cirvale

FIBERGLASS
Known as FR-4 (Flame Retardant Class 4) it has low moisture absorption, excellent mechanical resistance and excellent dielectric properties, presenting longer service life in humid, aggressive and higher salinity environments. It has excellent dimensional stability and high temperature resistance, with greenish hue and various thicknesses such as: 0.8 / 1.0 / 1.6 / 2.4 and 3.2 mm. The most widely used thickness is 1.6 mm.
