HTLT™ is an optical
grade thermoplastic that is characterized by a high index of
refraction, excellent transmission, and a sustained operating
temperature up to 150° C. It is a tough, impact resistant
thermoplastic that can be injection molded with precision detail at
high production rates. Given its high glass transition temperature
and excellent thermal insulation properties,
HTLT™ parts are suitable for use in solder
reflow processes including lead-free solder reflow applications.
HTLT™ Thermoplastic is
available in several grades and is recommended for use in producing
optical quality lenses for LED’s, cellular camera phones and other
photonic applications.
