RISHOLITE® Phenolic Sheets
Introduction
RISHOLITE® Phenolic Sheets come in several grades which in general offer excellent electrical insulation, mechanical strength, heat stability, wear resistance and economy to different degrees depending on the type of reinforcement used (ie. Paper, Cotton or Glass fabric). They follow JIS* (Japanese Industrial Standards) and NEMA** (National Electrical Manufacturers Association, USA) classifications on the structure of the materials.
RISHOLITE® Phenolic Sheets are available in various standard sizes, from 1000 x 1000 mm to 1200 x 2000 mm, with a range of thicknesses:
Phenolic/Paper sheets - 0.2 to 50 mm
Phenolic/Woven Cotton sheets - 0.5 to 100 mm.
Phenolic/Woven Glass sheets - 0.3 to 2.9mm
* PL-PEV, PL-PEM, PL-P-P, PL-PEM-P, PL-P-PF, EL-PEF, PL-FLE, PL-FCM, PL-GH ** XX, XXX, XPC, XXP, LE, C, CEM3, G3, G10, G11, FR1, FR3, FR4, FR5
