Driven by the energy revolution and the rise of high-end manufacturing, the market for high-performance insulation materials has seen significant growth. Among them, PMP Insulation Paper (polyimide film) has become an irreplaceable basic material in key areas such as ultra-high voltage power equipment, new energy vehicles, and aerospace with its unique comprehensive performance.
The core value of PMP Insulation Paper lies in its excellent tolerance to extreme environments:
"High temperature guard": It can withstand high temperatures above 250°C for a long time, and even exceed 400°C in a short period of time, far exceeding the limits of common insulation materials, ensuring the safe operation of equipment under harsh conditions;
"Chemical shield": It exhibits excellent resistance to strong acid and alkali solvents and oils, significantly extending the service life of components in corrosive environments;
"Power and electricity dual excellence": It has both high mechanical strength and stable insulation performance, providing a double protection barrier in complex working conditions such as high voltage and strong vibration;
"Light and tough balance": The high strength-to-mass ratio provides support for weight reduction and efficiency improvement of precision equipment, which is particularly in line with the needs of the aerospace industry.
Downstream applications drive capacity expansion
With the accelerated layout of UHV power grids, the evolution of new energy vehicle motors to high power density, and the deepening of aerospace technology, the demand for high-end PMP Insulation Paper has exploded. According to data from the China Insulation Materials Association, the compound growth rate of the domestic special insulation film market has exceeded 18% in the past three years, and there is huge room for domestic substitution. Domestic leading manufacturers such as Ruihuatai and Times New Materials are accelerating production expansion and technological research to break the overseas monopoly in high-end fields such as corona resistance and thermal conductivity.
