Perforated every 19” across as well as down the center of the length of the roll. More absorbent and a more cost effective alternative than oil based polypropylene sorbent rolls. Coverstock is only on the top side of the sorbent roll to allow roll to instantly begin soaking up liquid, keeping the roll firmly in one place and still having the durability that customers have come to expect from the Eversoak® line of absorbent. Class A fire retardant when roll is dry (lab tested per ASTM E84).
