Glass based laminates (also known as SRBGs or synthetic resin bonded glass) are made by mixing glass base materials with a variety of synthetic resins utilising high pressure laminating processes. Glass-based laminates are well-known for their outstanding electrical insulating qualities, but they also have great mechanical strength, excellent chemical resistance, and minimal moisture absorption.
SRBGs are often much denser than their fabric and paper counterparts, resulting in improved temperature stability, reduced smoke emissions, lesser toxicity, and flame retardancy.
Glass-based laminates outperform all other laminate grades in our offering in terms of mechanical qualities. The laminates are roughly 1.8 to 2 g/cm3 because glass fibres are substantially denser than cellulose (cotton or paper). The resin system determines other attributes like flammability, temperature stability, electrical, water absorption, and insulation resistance.
