APPLICATION EVALUATION
Start with the complete manufacturing requirement.
- Fiber design and target coating dimensions
- Coating and thermal-processing conditions
- Intended operating environment
- Application-specific thermal and mechanical evaluation
Cured-film Tg and decomposition temperature are material-analysis values. They are not continuous-service temperature ratings.

TECHNICAL FAQ
Questions for application planning
Does a 550°C decomposition temperature mean continuous use at 550°C?
No. It is a cured-film material-analysis value, not a continuous-service rating.
What information is needed to evaluate PI-250?
Provide the fiber design, coating dimensions, processing conditions, operating environment and required evaluation methods.
Is PI-250 the same material route as a dual-layer UV-curable system?
No. PI-250 is a polyimide coating route and should be evaluated according to its own processing requirements.
