Cured in Place Pipe

For over 30 years e² has been extrusion coating needle punched Polyester and Polypropylene felt/fleece in widths up to 120” for Cured In Place Pipe and for a variety of other applications.

At e², we have the ability to toll coat customer’s provided fleece/felt or our own locally sourced fleece/felt. Polymer options include TPU (thermoplastic Polyurethane), TPO or PE (Polyethylene). Our capabilities allow us to apply these polymers to fleece/felt ranging in weights from 3.8 ounces to 35 ounces per square yard.




For our customers who fabricate expansion tubes, we manufacture expansion bladder substrates. These products are available in PVC (Polyvinyl Chloride) or TPU coated woven nylon reinforcement up to 60’ in width.  Available in 13, 17, or 23 ounces per square yard weights.



We also provide fabrication accessory products including welding tape and resin pellets produced using the same resin as the aforementioned products.  These products can be utilized with your automated welding equipment whether welding a tape or extruding a tape over your stitching. 



e2 utilizes a “single-pass” extrusion process to ensure superior bond strength by entanglement of fibers into our molten stream and reduces the frequency of pinholes. Finished products are continuously tested during the manufacturing process to monitor coating uniformity, mass, and weight distribution. During and after manufacturing each roll is sampled and destructively tested for tensile, tear, and coating adhesion. All of this in and post-process testing is conducted to ensure that you receive a product that meets your specifications.
