Polycarbonates, are a particular group of thermoplastic polymers that are easily worked, moulded, and thermoformed. They are temperature resistance and high impact resistance and have amazing optical properties. Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. In the past Polycarbonate was not very UV resistant and tended to fade very quickly, however new technology allows the manufacturers to co-extrude an acrylic layer onto the polycarbonate that renders in UV resistant.
Clear, Light and Dark Bronze
- Long lengths of sheet available, up to 12 m.
- High Impact resistance - Polycarbonate has excellent impact resistance, approximately 250 times that of plate glass.
-Colour is consistent between batches.
- Can be cold rolled into a tight radius.
- Does not get "crazing" (stress fractures) when rolled into tight bends.
- UV resistant.
- Not suitable for vacuum forming.
- Low Scratch resistance.
- Not Chemical resistant.
- Not suitable for flat applications unless very thick.
- High cost, however due to its light weight this cost is negated by a cost saving in the support structure.
Polycarbonate is generally used in barrel vaults.
