Primol™ 542

Primol™ 542 is a colorless, odorless and tasteless purified mixture of liquid saturated hydrocarbons. The clear oily liquid is obtained from petroleum through several refining stages, including an ultimate purification by catalytic hydrogenation. Some of its features include:

  • Manufactured to exceed the purity requirements of the Pharmacopoeias
  • Superior chemical inertness
  • Demonstrates better color and oxidative stability than most mineral and vegetable oils, when stored and used under controlled conditions.

ExxonMobil White oils are produced and controlled according to the ExxonMobil Product Quality Management System, EN ISO 9000 or equivalent standard.

PDS Data sheets

Applications

Primol 542 can be used in a variety of food-related, cosmetic and pharmaceutical applications subject to the applicable laws and regulations in each country (*).

Thermoplastics

Primol 542 is recommended as a food packaging-grade plasticizer in Polystyrene. It offers an outstandingly low volatility but due to its high molecular weight, it is best used in grades at relatively low oil content, in order to maintain transparency for General Purpose PS grades.

Primol 542 is recommended for use as an external lubricant for non-plasticized PVC.

Elastomers and Adhesives

Primol 542 is used for producing food-contact or medical rubber articles, such as EPDM or butyl rubber. Because of its extremely low volatility, it is particularly well suited for the extension of Thermoplastic Elastomers when low fogging properties are required.

Primol 542 is also recommended for Hot-Melt Adhesives formulations used in sanitary products.
