PIR-001 polyimide resin
Polyimide Resin Powder is synthetic polymerized resin,and smashed into fine powder by airflow. It has excellent heat stability, mechanical and dielectric strength, radiation and chemical resistance,etc., widely used from automotive industry and aerospace to industrial applications and office machines.
Characters:
* Excellent heat resistance. * Excellent dielectric performance. *Higher mechanical strength, better tear resistance and flexibility.
*Machinable with standard tools * Low wear and friction * Good compatibility with fillers

Reference work process for polyimide resin powder in grinding wheels:
Recommended curing temperature: around 230℃;Recommended heat pressure: 30-60MPa
1.When mould temperature reaches around 160-170℃,start gas emission for 3-5times. Emission time depends on real situation of final users. Curing time can
also be increased or decreased based on real situation of final users.
2.For primer coating,the primer solution should be applied thinly to the roughened bonding surface (using a brush) and dried for about 10 hours at 250 °C.
3.For release agent,we recommend silicone oil spray to be applied in a very thin coating on the mould surfaces
4.With regarding to fillings for polyimide resin diamond grinding wheel, relies on end users.
Note:1.polyimide resins are hygroscopic, please predried at 250 °F (120 °C) for a couple of hours before any use
