（１） Low dielectric polyimide can produce ultra-low dielectric polyimide according to resin structure design and raw material matching technology.（２）Low dielectric loss tangent polyimide can produce low dielectric loss tangent polyimide according to resin structure design and raw material matching technology.（３）Transparent polyimide and polyimide film are designed according to the resin structure to produce transparent polyimide paint and film. Compare the solid content and viscosity of other companies■High solid content reduces cost (few solvents) reduces coating times - improves productivity ■High viscosity film uniformity, high insulation reliability and minimum raw material cost

Fast flocculation ability through strong stirring, firm and fast flocculation of oil components in water, solid-liquid separation, reduction of wastewater discharge (95 ~ 98%) and reuse of water. Form large flocs with good dewatering performance, and the sludge is also hydrophobic, so as to form sludge that is easy to dehydrate and no longer dissolves. Improving water quality can fix, separate and separate P...
