We have proprietary rights to the polyol formula in the US known as Pedero Pipeline Foam. Pedero’s proprietary foam formula is produced under the strictest ISO regulations, thus ensuring high quality goes into every Pillow and Breaker we spray. Because of this exclusive formula, our foam can be accurately sprayed up to 300 feet from the rig. Our formula is the only one you can count on not to cause pipe buckling or combustion fires. If you have heard any unfavorable news about polyurethane foam, it most assuredly was not Westell©.
