VIVAK®
VIVAK sheet offers an unheralded array of performance
characteristics ready for today’s design engineers in electronics, food, medical
and other industrial environments. VIVAK can be formed and handled in large,
thin sections and also die-cuts and punches easily, unlike acrylic which
requires costly routing, drilling and labor intensive cleaning. VIVAK sheet's
inherent strength also means less breakage during production, which can mean
higher margins and lower costs. It can be bonded or fastened with adhesives,
ultrasonic welding or rivets, and is compatible with standard screen printing
inks.

Notes:
VIVAK sheet, like any thermoplastic, has its performance limitations under
specific conditions and in particular environments, which the user should
consider.
For Example:
VIVAK sheet’s heat resistance of 145ºF precludes its use in heat generating
applications where typical temperatures exceed 140-145ºF.
