Polymer Quenching Medium/Quenching Oil


Polymer Quenching Medium/Quenching Oil

Heat treatment completely changes the properties of steel, whose structure is changed by heating and quenching. Both pencil leads and diamonds are composed of the same carbon, but look quite different. This is because the molecular structure of the former is random, but that of the latter is regular, as a result of the high temperatures and compression caused by as a result of changes in the earth’s crust. This is an example of the discovery by pioneering researchers that selecting specific heating and cooling temperatures produce various material structures.
Metal heat treatment is a kind of “modern alchemy”. The media used to quench heated metals are water, oil and air cooling. In recent years, polymer quenching agents, gas cooling, etc. have also been. Below is an overview of our quenching oils and polymer quenching agents.

Product Lineup

Polymer Quenching Medium

As water-soluble media, these media have no flash point. Desired hardness can be obtained by controlling the water concentration.

  • Parquench 60 (The chief ingredient: polyvinylpyrrolidone

    Recommended for use with crack-sensitive steel like S50C, SCM440.

  • Parquench 90 (The chief ingredient: same as above)

    Used for high carbon steel and alloy steel with good hardenability.

  • Parkerquench 525 (The chief ingtredient: Polyalkylene glycol)

    Used in a wide range of heat treatments, such as induction hardening, hardening in atmospheric furnaces, etc.

  • Serviscol 98 (Chief ingredient: same as above)

    A polymer quenching concentrate that meets the severe requirements of German health & safety guidelines. Effective even for steels with poor hardenability.
