High Flexural Strength EPGC202 sheet with 48*78 feet low water absorption FR4 epoxy glass cloth sheet
High Flexural Strength EPGC202 sheet are made of woven glass cloth impregnated with epoxy thermosetting resin,laminated under high temperature and high pressure ,the woven glass cloth shall be alkali-free and treated by silane couple
Feature:
Good mechanical strength(the thermal state retension rate can reach over 50%)under medium temperature or the thermal state,as well as the stable electric properties(the insulation resistance after immersion reachers 10^12Ω)in high humidity condition .and also with higher voltage end urance /withstand voltage (over 35KV),parallel to laminated ,and they also have Good flame retardant property.the sheets also passed the toxic and hazadous substance detection(RoHS Report)
Application:
1. phase and end barriers,
2. insulating supports,
3. bus bar supports,
4. mounting panels in switch-gear,
5. switch cabinet,
6. motor,
7. frame breaker,
