PPO Film Electrical Application
문제 현상
[Problem Phenomenon] Electrical insulating films need heat resistance and low dielectric constant; conventional films have insufficient temperature resistance
원인 분석
PPO film is made by maleic anhydride reaction casting, with a dielectric constant of 2.5-2.6 and heat resistance; reaction modification has little effect on the original properties and good film-forming property; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Select PPO reaction-cast film for heat-resistant insulating films; measure dielectric properties according to the frequency band; control film thickness uniformity according to electrical requirements; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PPO film with a dielectric constant of 2.5 plus heat resistance is a high-end option for electrical insulation; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
