Application Advice

Dissolving:

  • M50 is soluble in many organic solvents such as esters, ketones, aromatic hydrocarbons, and lower alcohols.
  • M50 should be added carefully to the solvent system under sufficient agitation to ensure dispersion and suspension of the polymer beads.

Melt:

  • M50 is thermoplastic and will gradually soften and flow with increasing temperature. At >140°C, the polymer can be mixed as received with EVA resins to formulate thermomoldable fabrics. Resins with a higher vinyl acetate content generally show better compatibility.
  • M50 can also be used in the formulation of automotive sound damping foils by compounding with appropriate pigments and plasticizers. Heat-activated coatings and adhesives can also be easily formulated.

Compatibility:

  • M50 is compatible with other M Grade polymers and can be mixed in any proportion to modify either solution or dry film properties.
  • M50 can be plasticized with many types of plasticizers to modify film properties.

Applications:

  • Solvent-based general-purpose adhesives, parquet flooring adhesive, solvent-based inks & coatings, automotive sound damping foils, heat seal adhesives, low-profile additive for polyester composites.

Storage & Handling

Storage Conditions
  • M50 is a thermoplastic solid. To prevent sticking of the polymer beads, M50 should be stored in dry conditions, below +20°C (+68°F) out of direct sunlight.
  • Pallets should not be stacked. Under these conditions, M50 has a storage life of at least 24 months from the date of manufacture.
  • M50 has been stored for longer than 24 months should be tested before use.
