Polycarbonate
American Made Plastic Sheet, Plate and Rod
Makrolon®, Lexan®, Zelux®, Unicar®, Ensicar®
Why use Polycarbonate:
- Very Tough Material
- Extremely High Impact Strength
- U.V. Stabilized and Light Weight
- Bondable, Paintable, Printable and Silk Screenable
This material is…
excellent for impact strength (one of the highest in the plastics family), is UV Stabilized and light weight. Has excellent transparency in thin gauge (.030″ – .500″ in glazing grade / also .250 – 2.0″ in Zelux ‘W’). Can be heat bent and formed (requires drying prior to heating). Can be bonded and fabricated well with standard cutting tools. A very durable and high performance thermoplastic resin.
- Extremely High Impact Strength
- Good optical properties in thin gauge
- Can hammer a nail through sheet without breaking the material
- Can be formed, bent, cut and worked with standard cutting tools
- More than 25 times more impact strength than Acrylic (Plexiglass)
- Can be cold formed or bent – eliminating some heat forming
This material is used frequently for shields, guards and containment barriers. Can be cold or heat bent to most configurations. A popular material manufactured by several companies: Lexan® by SABIC, Makrolon® by Sheffield/Bayer, Zelux® by Westlake, Unicar® by Nytef, Ensicar® by Ensinger, Cyrolon, Tuffac, Apec, Trirex, Paltuf, Texin.
