KYDEX 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 .375 and can be thermoformed, post formed, brake formed and laminated.
modulus of elasticity in flexure is 330,000 psi.
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.
relatively hard thermoplastic, with a hardness of 90 on the Rockwell R scale. This hardness, combined with a grained surface, increases its abrasive resistance.
low flammability, UL 94 classification V-0
For some applications it is used as replacement for leather, where it has the following advantages:
scratch resistant (Rockwell "R" hardness of 90)
holds its shape better, and will not stretch or shrink under normal conditions
***You may want a Kydex sheath or holster made specifically for your custom knives, axes, guns etc...
Here are some examples of my custom made sheathes -
KYDEX™ comes in a wide variety of colors, textures, patterns and prints. Most of my sheathes are made with .08 Kydex and 1/4" rivets and Chicago screws.
