Woven glass fibre roving fabric made from heavy untwisted “E” glass yarn having resin compatible surface-dressing or size. Woven roving are often used in composite laminates with chopped strand mat, later being used to increase the bulk of the laminate. Rovings wet far more quikly than certain types of mat, pick up a lower percentage of resin (i.e. approximately 50% glass 50% resin), and have far better physical properties. A roving laminate is much stronger than laminate made from chopped strand mat and a thinner, lighter and less expensive laminate can often be made.

Fibreglass Varnished Fabrics are normally used for application where operating temperature is class ‘B’ (130 °C) or above. Fibreglass Varnished cloth and tapes can be used for wide variety or electrical applications where material with high tensile strength and flexibility is required. Composition: A low alkali content ‘E’ glass fabric heat cleaned and treated with coupling agent is impregnated with glyptal type varnishes. The glass fabric imparts good mechanical properties while varnish possesses high dielectric strength. Materials are available in straight cut and bias cut form.

Our Insulation Crepe Papers offer superior flexibility and durability, making them ideal for applications requiring conformability and high dielectric strength.
