What is Kydex material

Kydex is a line of thermoplastic acrylic-polyvinyl chloride materials manufactured by Sekisui SPI. It has a wide variety of applications, including for aircraft bulkheads, firearm holsters, sheaths, and for knives.



Similar acrylic polyvinyl chloride material (IPK Acrylic-polyvinyl chloride) is manufactured by Emco Plastics and Interstate Plastics, which carries nearly identical properties with an added layer for screen printing.



It is an acrylic-polyvinyl chloride composite engineered for thermoforming fabrication, and combines properties of both the acrylic and the polyvinyl chloride components. From acrylic, it obtains rigidity and formability; from PVC, toughness, chemical resistance and good interior finish ratings. Sheet thickness ranges from .028 to .500 inches and can be thermoformed, post formed, brake formed and laminated.


1.    Flexural modulus is 2,758 MPa (400,000 psi)

2.    Parts formed from sheet will be rigid and will see moderate deformation when loaded. This is of particular importance in deep formed parts with thin wall sections.

3.    Relatively hard thermoplastic, with a hardness of 90 on the Rockwell R scale. This hardness, combined with a grained surface, increases its abrasion resistance.

4.    Low flammability, UL 94 classification V-0.



1.    Waterproof.

2.    Scratch resistant (Rockwell scale "R" hardness of 90).

3.    Holds its shape better, and will not stretch or shrink under normal conditions.

4.    Lower friction.
