JHPI-10
JHPI-10 powder
JHPI-10 sheet material
It has the highest temperature resistance rating, with a long-term operating temperature of 350-380℃. Its disadvantage is that it is relatively brittle and not suitable for thin-walled or impact-sensitive products.
JHPI-20
JHPI-20 powder
JHPI-20 sheet material
It has a long-term operating temperature of 350℃ and an instantaneous temperature of over 400℃. It has excellent processing performance, good toughness and rigidity, and strong mechanical properties.
JHPI-30
JHPI-30 powder
JHPI-30 sheet material
It has a long-term operating temperature of 300℃ and excellent processing performance;
YS-20
YS-20 powder
YS-20 sheet material
High-transparency polyimide (PI), with a long-term operating temperature of 220℃, is suitable for applications such as high-temperature insulating components, wear-resistant parts, gaskets, and washers.
