membranas manufactures electrical grade, high-purity pressboard in sheets, made entirely of high-strength and purity sulphate (Kraft) unbleached cellulose fibers. most of our manufacturing equipment was designed or modified in-house and it's built to maintain the fiber's purity and adequately develop its mechanical strength.
​
we produce mostly low-density calendered-type board but can also customize materials for client's needs by modifying density, flexibility and make special thicknesses that are not commonly available on the market.
​
with over 25 years of expertise in insulating pressboard, membranas has continuously supplied all mexican oems of oil-filled distribution transformers and exported our board to north and south america.
