The Science Behind DymondPly

At Ridge, fiber orientation and thermoplastic resins used in our composite products combine to create an extremely durable material that is impact and abrasion resistant. Dymond Liners multidirectional fiber design gives the panels the strength and stiffness they require in order to fight against abuse with the least amount of weight. The high-strength fibers are imbedded in a durable thermoplastic resin, which give the liners their stability and design flexibility. Together, the thermoplastic resins and reinforcing fibers create one of the most versatile lining materials that is also 100% recyclable.

Ridge Corporation is proud to offer products that are 100% recyclable.
