FORMULATION DEVELOPED

MATERIALS STUDY :
Formulation:

Matrix :Blend of EVA (High VA content : 50/90%)

  • Oil resistance
  • Easy grafting
  • Flexibility

Fillers : Blend of ATH/MDH

  • Fire resistance
  • Can have an impact on oil resistance

Plasticizer :

  • Flexibility
  • Elongation at low temperature

Crosslinking system : Silane

  • Nature and ratio of peroxide/silane very important
Process of production:

A silane modified process : Silane

  • All polymers can be used
  • All formulations can be used
  • Easy to pellatize
  • Dried blend
  • Easy extrusion

Concerns : Blend of ATH/MDH

  • Adaptation of the production parameters to the formula
  • Control of the order of components incorporation
