Convolute rolled composite tubing grades are available in a variety of resin and substrate systems.

Fiberglass tubes consist of fine or medium weave glass reinforcement combined with an epoxy, phenolic, melamine, or silicone resin system. Meeting the requirements of ML-I-24768 and NEMA G-5, G-7, G-9, G-10, or FR-4, these grades offer a variety of properties, including high temperature resistance, excellent electrical and mechanical properties, and arc and flame resistance, depending upon the resin system selected. These products are designed for applications requiring high electrical and mechanical strength and the ability to withstand harsh environmental conditions. Glass fabric substrates can be abrasive in certain applications.

Composite tubing grades are also available with fine or medium weave cotton fabric reinforcement with a phenolic resin system. Meeting the requirements of ML-I-24768 and NEMA C or LE, these composite materials are used in mechanical applications where electrical strength is of secondary importance. Some grades include self lubricating modifiers for mechanical and friction reduction applications.
