Hydlar Z - Nylon/Kevlar
What is Hydlar Z?
Hydlar Z is a relatively new plastic. It was first formulated by the scientists at A.L. Hyde Company in 1984. Hydlar Z is Kevlar fiber reinforced Nylon 6/6. With the addition of Kevlar, Hydlar Z’s properties improve, better dimensional stability is achieved and wear resistance is increased ten times that of unfilled nylon.
Hydlar Z can be machined by conventional methods using the same standard tools used to machine unfilled Nylon 6/6. When compared to nylons which have been filled with glass to achieve similar strength and temperature resistance, Hydlar Z is far less abrasive and easier to machine. Because of its lower water absorption and stability, close tolerances can be machined with this product without fear of dimensional change after machining.
The FDA has not approved Hydlar Z. While lower in cost than many high temperature thermoplastics, Hydlar Z can be more costly than glass filed or unfilled Nylon 6/6.
