Technical Data

Product Range

VIVAK® is a clear transparent sheet made from thermoplastic co-polyester (PETG). It offers extreme clarity and light transmittance and high gloss level. In addition, it has high impact resistance, even at low temperatures and is approved for food contact applications. With superior thermoforming and mechanical properties, VIVAK® offers designers a high degree of design freedom.

VIVAK® sheet offers deep draws, complex die cuts and precise moulded-in details without sacrificing structural integrity. It can be bonded or fastened with adhesives, tapes, ultrasonic welding or rivets. In addition, VIVAK® sheet is easily decorated by painting, silk screening or hot stamping. It is also easy to fabricate, form, bond and decorate.

VIVAK® sheet products offer virtually unlimited options for complex shapes and objects in applications that range from industry to visual communications, to specialised purposes in the medical field.

With their ease of fabrication even at low temperatures, they ensure low energy consumption and high productivity. Manufactured in Australia by Bayer MaterialScience under strict quality control meeting ISO 9001:2000 certification guidelines for both plant and process.

Thermoforming

Owing to their excellent flow and mold surface reproduction, VIVAK® sheets can be thermoformed
at low temperatures without predrying. Because of its low specific heat capacity, VIVAK® requires little
energy for thermoforming.

Permanent Service Temperature

The permament service temperature is approx. 60 °C.
