RETSAR heat-resistant electrical insulating self-fusing radiation cure rubber glass cloth

RETSAR heat-resistant electrical insulating self-fusing radiation cure rubber glass cloth

RETSAR heat-resistant electrical insulating self-fusing radiation cure rubber glass cloth is produced from fiberglass and organosilicon rubber using radiation curing method. RETSAR has self-fusing ability within 48 hours at (25±5) °C or within 3 hours with additional heating at (150±3) °C. It features high water resistance, resistance to ozone, ultraviolet rays, some oils (turbine, transformer oils) and some chemicals, complete absence of toxicity.

Application Characteristics

Application

RETSAR heat-resistant electrical insulating self-fusing radiation cure rubber glass cloth is intended for use in the electrical industry as insulation for winding elements of electrical machines and devices operating in high humidity and high temperature conditions. RETSAR is used for flexible shunts and leads of AC and DC electrical machines, electrical harnesses, cables, busbars and current conductors. This material can be used both on its own and in combination with LETSAR tape.
