Inorganic Polymer Glass (IPG)

XBH 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
Does not suffer 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
