Where did ‘ScotchPly’ Go?

ScotchPly- a product created by 3M in the mid 1950s- is notorious for it’s strength in high vibration applications, such as vibrating conveyors. The material was sold exclusively through 3M for several years until Cytek (Solvay) purchased the brand and formulations. The brand name was then changed to ‘CyPLY’ until the product line was purchased by Norplex Advanced Composites around 2020. ScotchPLY is now sold under the trade name ‘NorPLY™’ with distribution rights through Franklin Fibre – Lamitex Corp. 

Adding our precision fabrication to the original ScotchPLY material formulation guarantees customers that they will receive superior parts than in the past. 

Why NorPLY? 

Like many of our other composite materials, NorPLY is made of a glass-based reinforcement saturated with a thermoset epoxy resin matrix. What sets this material apart from a typical G-10 / G-11 etc. lies within the lay up of the fabric. Instead of a cross-woven pattern that most NEMA grade composites use for their base reinforcement material (picture a linen table cloth), NorPLY uses a unidirectional lay up method. This means that all of the strands of material flow in the same direction. Layering these unidirectional laminations creates a product with exceptional flexural strength when compared to natural G10. For example; when testing to ASTM D229, unidirectional NorPLY material is able to reach 166,795 psi. – while natural Lamitex® G-10 is only able to get as far as 55,000psi.
