Frequently Asked Questions

Q: What temperature do I need to thermoform KYDEX sheets?

A: For 1.5mm KYDEX sheets, heat to 90–100°C (194–212°F). For 2.0mm sheets, heat to 100–110°C (212–230°F). Always use a controlled heat source and avoid exceeding the recommended temperature range, as excessive heat can cause unwanted shrinkage or deformation of the sheet.

Q: What projects are KYDEX plastic sheets best suited for?

A: KYDEX thermoform sheets are ideal for DIY knife sheaths, custom gun holsters, magazine pouches, tactical gear, cosplay armor, and any project that requires a rigid, lightweight, and precisely molded plastic panel. Their excellent thermoformability makes them a popular choice among makers and craftspeople.

Q: Which size KYDEX sheet should I choose?

A: The right size depends on the dimensions of the item you are forming around. For larger items like full-size gun holsters, the 300×300mm sheet offers the most material. For smaller knife sheaths or blade carriers, the 300×150mm or 300×100mm sizes are usually sufficient. The 1.5mm thickness is easier to form by hand, while the 2.0mm thickness offers extra rigidity for demanding applications.

Q: Can I cut KYDEX sheets with standard tools?

A: Yes. KYDEX can be cut with standard workshop tools including a utility knife (score-and-snap method), bandsaw, jigsaw, or rotary cutting tool. Edges can be smoothed with sandpaper or a file for a clean, professional finish.
