Advantage:
Insulation epoxy sheet has high mechanical performance at medium temperature and stable electrical performance at high temperature.
Application:
Insulation epoxy sheet suitable for high-insulation structural parts for machinery, electrical appliances and electronics.
Notice:
1. During slitting and use, edge gaps and cracks should be prevented to avoid tearing during operation and to avoid surface scratches, oil and dust pollution.
2. Store in an environment below 40鈩? keep clean and dry, away from heat sources, and avoid direct sunlight.
3. The storage period is one year. If it exceeds the storage period, it can still be used if it passes the test according to the technical requirements.Insulation Pressboard manufacturers
