  • Patent number: 11028226
    Abstract: A high temperature resistant polyimide film and its preparation method. The present invention relates to a polyimide film and its preparation method and solves the problems of honeycomb's and skin panel's core adhesive—polyimide film with insufficient heat resistance, no climbing of bonding core structure and adhesive fillet formation. The high temperature resistant polyimide film is made by polyimide solution, inorganic filler modifier and interface coupling agent by the steps of: under specific temperature and stirring conditions, adding inorganic filler modifier and interface coupling agent to polyimide solution, stirring to obtain the adhesive agent; filtering and degassing the adhesive agent, casting to a stainless steel drum with carrier cloth and release paper to obtain a self-supporting film; then heating and annealing to obtain the final polyimide film. The present invention is applied to high temperature resistant polyimide film and its preparation method.

  • Patent number: 11015042
    Abstract: A composition comprising a tread enhancement additive for use in a number of applications including tires is disclosed. The tread enhancement additive is prepared from an unmodified alkyl phenol resin by reducing the hydroxyl value of the unmodified alkyl phenol resin, forming a modified alkyl phenol resin having a decreased hydroxyl value. The composition exhibits improved performance characteristics such as enhanced wet grip and decreased rolling resistance and improved abrasion resistance.
