Polyester Laminate HT 1220
Insulac-HT1220 high temprature glass polyester and high laminates offer temprature ratings of up to 2100C. Because of its capabilities, Grade HT1220 is adeal for a wide variety of product applications requiring high-temprature NEMA GPO-1 products. Grade HT1220 is also a suprier replacement for epoxy bonded mica in layer insulation application.
The material is know to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.
