Inorganic Polymer Glass (IPG)
DLC
produces and supplies
IPG, a superior quality "spin-on" optical polymer.
Inorganic
Polymer Glass (IPG) is a patented, highly stable inorganic polymer
with the processing and design properties of a flexible organic
polymer. It is made through a unique process. IPGs have highly
reproducible and stable optical properties, and IPG films have low
stress and high uniformity. IPG materials are uniquely suited for
the fabrication of high quality optical films and waveguides.
Features
Lower loss and higher temperature stability than
organic materials
Photosensitive patterning using mask
aligner, stepper or laser scanning
Highly reproducible and
stable optical properties
Low film stress and excellent index
and thickness uniformity
Tuneable properties such as:
Refractive index
Thermo-optic coefficient
Thermal
expansion coefficient
Advantages

thermal hysteresis unlike high Tg (glassy) materials
Makes low
stress films with very low PDL values
Stable to above 300 °C
Stable to chemical oxidation in oxygen environments
Very
good durability and stability
No thermal ageing
Excellent
resistance to moisture
Suitable for metallisation and
electrode patterning
Solvent free processing
High quality
films
Environmentally safe
Low cost shipping and handling
