Remark
- The value is representative.
VOC
VOC of developed resin is much lower than general resin.
Curing property
All resin can be cured at 150℃ except for PR-X22105.
Thermal decomposition
Thermal decomposition temperature of PR-X22100 is the highest.
Glass-transition temperature
All resin show higher Tg than 200℃ when cured at 200℃.
Especially, Tg of PR-56367 and PR-X22100 reach over 300℃.
Physical property of resin impregnated paper
PR-X22127 has less water-durability compared to the others.
PR-X22100 and X22104 have good heat-resistance and water-durability.
