Protect Yourself Against Breakdowns!

Irvington Black Varnished Cambric prevents insulation failures because of its high resistance, high dielectric strength, non-hygroscopic qualities, heat resistance and neutrality to chemical action.

Irvington Varnished Cambric is woven from special selected long fiber cotton.

The fabric is treated in our own bleachery by a special process which gives it a smooth uniform finish, increases its insulation value and mechanical strength.

Uniform coatings of any desired thickness are obtained by treatment in our own specially designed towers. Irvington insulation in silk, cotton or paper and punched form, washers, tubing or odd shapes, can be supplied to meet your requirements.
