Explore Our Composite Materials

• G10 Composite

  A fiberglass epoxy laminate known for its rugged strength and water resistance, G10 is a go-to for durable, high-grip knife handle scales and other rigid components.

• HDPE Sheets

  Trusted for mold making, HDPE is a cost-effective, easy-to-machine option for building custom press and vacuum molds for sheaths and holsters.

• Tegris Composite

  A lightweight, woven thermoplastic that delivers high-impact resistance—Tegris is ideal for tactical gear, hard shells, and slim, rugged sheath designs.

• Curv Composite

  Curv offers a balance of stiffness, light weight, and excellent thermoform-ability, perfect for high-output holster production and custom tactical parts.

• Proform Board

  Purpose-built for mold making, Proform Board is a heat-resistant, dimensionally stable tooling block that outlasts HDPE for long-term forming use.

Built for Makers

Whether you're manufacturing at scale or prototyping a new holster, our composite materials offer the strength, consistency, and versatility needed to get it right the first time. From knife handle material to thermoform mold bases, Index Thermoplastics is your source for advanced composites.
