Oil emulsion ME-50/42

Product description

Oil emulsion ME-50/42

Features

Oil emulsion ME-50/42 is a solvent free aqueous emulsion of mineral oil. It is intended for dedusting and additional water-repellent treatment during manufacturing of various materials, including fiberglass and mineral wool products, treated by phenol-formaldehyde resin.

 

Applications

Oil emulsion ME-50/42 is used in conjunction with a binder in the production of heat-insulating materials:

  • production of mineral wool (basalt wool or stone wool) and derivative products - plates, insulations, acoustic panels, etc.
  • manufacture of glass wool and derivative products

Oil emulsion ME-50/42 addition to phenol-formaldehyde binder composition:

  • provides the binding of dust generated during the destruction of silicate fibers as a result of mechanical stresses (when cutting mats),
  • provides a friction decreasing between the fibers in the material (improves organoleptic characteristics),
  • imparts the materials a hydrophobic effect, that is, prevents moisture from entering the material, which significantly impairs the heat-insulating characteristics of the material and contributes to its destruction.
  • performs the function of fiber plasticizer, thereby reducing the fragility of the fibers in the finished product (mineral wool boards, glass wool, panels, etc.).

To improve the hydrophobic properties, it is recommended to use it in conjunction with the silicone emulsion SE-50/12.

Advantages

  • Oil emulsion ME-50/42 prevents the formation of fine dust during the production of mineral wool (mineral wool carpet), fiberglass, and during subsequent processing of finished products - rolling the carpet, cutting mats made of fiberglass, mineral wool.
  • The addition of oil emulsion reduces the water absorption of mineral wool insulation (glass wool, stone wool, basalt wool).
  • Minimizes fiber fragility.
  • Increases the flexibility of the finished product, facilitates rolls folding.
  • Improves gas and vapor permeability of materials.
  • Accelerates and facilitates the installation of processed materials.
  • Reduces the harmful effects of dust on the human in the process of contact with mineral wool.
  • Reduces friction between fibers in the material (improved organoleptic characteristics).
  • The components of the binder (resin, ammonium salts, aminosilanes, etc.) do not have a destructive effect on the emulsion.
  • High flash points reduce smoke and the risk of ignition during production.

Oil emulsion processing technology

Oil emulsion ME-50/42 is applied by spraying together with binder and other additives.

To precipitate the forming fibers, dusting reducing and plasticizing, it is included in the composition of the binder solution in the form of a 50% emulsion in an amount of 2-3% introduced directly into the reactor where the binder solution is prepared.

When applying the emulsion ME-50/42 together with the emulsion SE 50/12 the mixing ratio is one weight part of the emulsion SE 50/12 for 3-5 weight parts of the emulsion МE 50/42.

Reprocessing of fiberglass and mineral wool products after curing of the emulsion МE 50/42 (or mix of emulsions МE 50/42 and SE 50/12) is not recommended.

The amount of applied emulsion МE 50/42 (or mix of emulsions МE 50/42 and SE 50/12) depends on the desired properties of the end product, therefore, to determine the optimum quantity, individual tests must be carried out. Normally, the sufficient amount of emulsion (or mix of emulsions МE 50/42 and SE 50/12L) is 0.6-1.2% by weight of dry fibrous material.

Always test the selected concentration of МE 50/42 (or mix of emulsions МE 50/42 and SE 50/12) on the trial sample to  determine the optimal amount of material and the suitability for use in a particular case.
