  • the membrane 1 is polymerized under elevated pressure.
  • the polymerization parameters such as pressure and temperature may vary depending on the specific plastic.
  • Essential is the increased pressure, typically 2 bar.
  • the improved repair properties can be attributed both to the increased internal pressure of the foam cells or bubbles (3) and to a conformational change or structural change within the foam, which has a positive effect on the repair, i. Sealing behavior exercises.
  • the repair behavior could be further improved by measuring the amount of polymerized polymer per unit area: with a coating amount in the range of 1 to 2 g applied on an area of about 20 cm 2 (circular sample with 5 cm diameter) better results were obtained Self-healing or repair behavior achieved than with a lying outside this range coating amount.

  • prepolymers are provided in a suitable form, which polymerize in contact with air and the moisture contained in it. Typically, such polymers form bubbles on contact with atmospheric moisture, which are drawn into the hole 4 and fully harden there.
