UPGM Series Insulating Sheets  

UPGM (unsaturated polyester glass mat) is rigid insulating material made of alkali-free glass mat impregnated in unsaturated polyester resin and additives, cured by heat and pressure. This series of materials exhibit excellent electrical and mechanical performance, widely used in rail transit, photovoltaic industry, wind power, power transmission & distribution, metallurgy, mining, petrochemical industry, public transport, etc.

UPGM-201: stable electrical performance in high humidity, good mechanical performance at moderate temperatures, for mechanical and electrical applications.
UPGM-202: good mechanical and electrical properties, good mechanical performance at moderate temperatures, good flame and fire resistance.
UPGM-203: similar to UPGM-202 but with improved arc and tracking resistance, for mechanical and electrical applications.
UPGM-204: superior to UPGM-203 with higher mechanical strength and heat resistance, designed for harsher conditions, no flame resistance.
UPGM-205: for mechanical and electrical applications, excellent mechanical and electrical strength at room temperatures, excellent heat resistance, good performance against arc and tracking, toxic-free, flame resistant, and low smoke.
