Primol 542
ExxonMobil specialties , Thailand
Product Description
Primol 542 is a purified mixture of liquid saturated hydrocarbons. It is a colourless, transparent oily liquid and is essentially odourless and tasteless. It is obtained from petroleum through several refining stages, including an ultimate purification by catalytic hydrogenation.
Primol 542 is manufactured to exceed the purity requirements of the Pharmacopoeias Due to its superior chemical inertness, it demonstrates better colour 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.
CAS number: 8042-47-5
EINECS number: 232-455-8
INCI name (Europe): Paraffinum Liquidum
CTFA Dictionary name (USA): Mineral Oil
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.
(*) User must check compliance with applicable regulations.
