▶ Electrical insulation stability under high temperature and medium humidity
- metastar in terms of the dielectric strength, constant and loss factors, Metastar Raramid paper is not significantly affected by high temperature below 300 C and humidity below 60%RH.
▶ Excellent paint absorption dielectric compensation ability
metastar aramid paper produces satisfactory impregnated insulating paint performance, fast paint absorption speed and high dip-coating saturation. With good uniformity, it does not leave any air cavities and the electrolytic strength increases after dip-coating It fully meets the application requirements.
▶ Low operation loss
metastar The dielectric constant and loss factors of metastar Raramid paper are relatively lower. As the insulation electric field is distributed more evenly, the conductor loss is reduced even more and the operation loss of the electric device is lowered as much as possible.
▶ Distinctive resistance to chemical corrosion
Metastar® aramid paper is soaked in ethanol, acetone, toluene, xylene, silicon and 25% transformer oil. In ten-weeks time, no considerable changes occur in the appearance, mechanical performance and electrical performance.
● Basic material for lightweight and high-strength bending slab
▶ Lightweight and high-strength honeycomb structure
- metastar A bending slab made using metastar® aramid paper produces the following characteristics.
① Lightweight: Aramid paper bending slab is lighter in weight by 50% than aluminum slab.
② Relatively High Strength: The strength is nine times higher than steel.
③ It produces strong impact resistance.
▶ Flame-retardant and non-toxic honeycomb structure
- metastar The bending slab made using metastar Raramid paper produces stronger flame resistance. In addition, it does not generate drips or toxic smoke, and thus can effectively protect human safety.
▶ Dimensional stability under low and high temperatures
- Metastar aramid paper produces dimensional stability under a temperature from -80°C to 200 °C. It does not involve intense thermal expansion and contraction as of metals. In addition, this material is very effective in terms of structural safety.
▶ With radiation resistance, this material can be used in long-distance flight.
- Metastar aramid paper produces high tolerance to beta and gamma rays, ages slowly and is suitable for application to aircraft components.
▶ With stable molecular structure, this material is strong against corrosion.
- metastar aramid paper is in a linear macromolecular structure, which is comprised of an aryl group where the molecules are connected with amide bond. The relatively high hydrogen bonding effect stabilizes the structure, increases chemical stability and gives tolerance to most chemical reagents.
▶ With excellent electromagnetic wave absorption performance, this material is suitable for stealth aircraft
- Metastar® aramid paper with excellent electromagnetic wave permeability absorbs electromagnetic waves through a special design as a bending slab. It helps in the aircraft stealth function.
