nynas PROCESS OILs knowledge tank

Having established in-house coating and testing of solid fertiliser, a Nynas researcher finds that naphthenic process oils offer coating formulations capable of reducing both dust and caking issues.

A recent study shows that silicone sealants extended with a Nynas naphthenic specialty oil display lower levels of microbial growth. Hence, Nynas extender oil can help sealant producers achieve a higher sanitary classification, securing CE marking for their products.

Producers of silicone sealants need look no further. Nynas has developed a range of specially designed silicone fluid alternatives that are cost-efficient and offer the right balance in formulations between viscosity, colour stability and volatility.

A recent study shows that a transparent RTV-1 acetoxy curing silicone sealant extended with 20 wt% naphthenic specialty products has a lower level of microbial growth compared to other extending alternatives in the market.

Anna Eriksson has held various positions in Nynas since 2006, covering product development, quality, customer support, research and application-specific education. She currently holds the position of Technical Manager Chemical Industry, coordinating technical activities with industry, customers, academia, test institutes and authorities. Find out what's on her mind.

The unique naphthenic characteristics of the recently introduced NYFLEX® 2120B oil promises the prospect of real innovation for the printing ink industry, allowing inks to be produced at lower temperatures.

High solvent power is the secret of the success of naphthenic oils in chemical applications. Anna Eriksson, Technical Manager, Nynas Naphthenics, offers a couple of examples that explain why.

Disposable nappies are changing, but not to the naked eye. The change is hidden in the polymers that make up the adhesives in their non-woven materials. Will Nynas specialty oils work in the ever-changing adhesives market?

By boosting the compatibility of ingredients, naphthenic mineral oils are providing hot melt adhesive manufacturers with new and more flexible formulations

Packaging tape sticks better when made with refined naphthenic oil. Comparing the impact of different oils, Nynas found a way to finetune the adhesive properties.

During the past few years, metallocene polyolefin elastomers (mPO) have become significant market players and are growing continuously in several industrial segments.

Solubility properties are crucial to process oils, particularly in relation to substances that need to be dissolved. Marika Joona, technical co-ordinator at Nynas R&D department, has investigated whether Hildebrand's solubility parameter can be used to describe the properties of process oils.

Pär Wedin at Nynas proposes a shift from one point to another one, from aniline point to turbidity point. Now, standardisation bodies SIS and ISO are mulling over his proposal.

The use of fertilisers around the world to boost agricultural production is both vital and constantly under critical scrutiny. Developing products that provide optimum benefits both economically and from an ecological viewpoint is an important challenge for the artificial fertiliser producer. Very small quantities of oil are employed in the production of fertilisers. The market demands optimal products and every link of the chain must be taken into consideration, including the properties of the oil being used.

Compatible with all sorts of rubber, naphthenic oil facilitates the dispersion of insoluble sulfur, the vulcanising agent used in the production of tyre rubber. Anna Eriksson explains how this helps improve the quality of the final rubber.
