The 1030HT fiberglass reinforced polyester sheet is manufactured under high heat and pressure in matched metal moulds. This laminate provides excellent mechanical and electrical properties for service temperatures up to 428°F. Testing shows that after 2000 hours of exposure at 390°F, the flexural strength is reduced by 10%, and the dielectric strength is reduced by 30% to 240 VPM.
This material is excellent for use in applications where high temperature property retention products are required, such as dry transformers.
