Advantages when compared with other special engineering plastics:
1. Compared with PEEK PPS, thermoplastic Pl is a non crystalline, showing better stability of mechanical properties and size at
high temperature condition. While the crystalline plastic will continue to crystallization or crystallization damage when using the
temperature between Tg and Tm, causing the mechanical changes and decreasing dimensional stability, creep resistance
reducing
2. Compared with PTFE, better dimensional stability, better creep resistance and high strength, the shortage is worse corrosion
resistance.
3. Stabler performance in the high or low temperature performance. The processing temperature can be 340-380 °C, lower than
Aurum. It no need heat treatment after the molding process.
4. Thermal properties: Tg:260 °C, HDT:250 °C, long-term use temperature is 240 °C. At the same time, also has very good
performance of low temperature resistant, will not brittle fracture at the temperature of -269 °C in liquid nitrogen.Compared with BMI
The performance of BMI is more brittle, it will break off during the use of the process.
SolverPI-Powder 1600X is showing as melting state during thermoplastic molding, the adhesion and toughness is better than not easier to be cracked
Usage life is longer. BMI can be used for 4 hours, while SolverPi-Powder 1600x can be used continuously for 72 hours.
Using temperature can be higher. SolverPi-Powder 1600x can keep stable within 240 °C
In the high-end abrasive in German are using polyimide as a binder.Application:
Press all kinds of machinery, electronic components, such as floating seal ring, sealing ring, bush pressed sheet, rod, diamond grinding tools etc.
The demand of high-grade diamond abrasive for thermoplastic Pl is big because the traditional adhesives can not meet their requiremen
