Multisol supplies packed naphthenic base oils to the grease and lubricant market sectors.
Brenntag UK and Ireland supplies packed naphthenic process oils to a diverse range of end-markets such as the adhesive, printing ink, plastics, agrochemical and construction sectors detailed below.
Which is your market?
Mineral oils are used as plasticisers for hot-melt adhesives (HMA) and use of naphthenic oils can improve the overall mechanical performance of the adhesive system especially compared to paraffinic counterparts.
Due to their HSE properties - such as low aromatic content and compliance with FDA(B) or FDA(C) classification – Nyflex oils can plasticise pressure sensitive adhesives (PSA) for use in non-woven hygienic, skin contact applications such as nappies as well as tapes and labels.
Nynas also offers plasticising oils for SBR-based adhesives used in flooring applications. The applicable Nytex grades combine the high solvent power needed for the plastification of these polar polymers with very high HSE standards, fulfilling the criteria of low aromatic concentration stipulated by the EU (Regulation 1907/2006/EC (REACH) Annex XVII.50).
• Printing Inks
Low and medium viscosity mineral oils are used in printing ink formulations for a number of different reasons.
This can include the naphthenic oils acting as a vehicle to "carry" or dissolve the other components of the ink formulation, to contribute to the pigment wetting process, to facilitate the ink deposition process and to being readily removable upon printing.
Nynas offers select products from the Nytex and Nyflex series for this application, ranging in viscosity from as low as 3 cSt to over 100 cSt.
The naphthenic products have the advantage over their paraffinic counterparts through a higher compatibility with a large number of resins resulting in a lower cloud point which gives a higher degree of freedom and ease of processing to the ink formulator.
The higher solvency power of Nynas products will also facilitates the pigment wetting process. For cold-set applications such as newsprint, their rapid absorption into the paper results in a higher print quality.
• Thermoplastic Elastomers (TPE)
Nynas products are used with great success by a broad customer base as plasticisers for Styrene-Butadiene-Styrene (SBS) and Styrene-Ethylene-Butadiene-Styrene (SEBS) type TPE materials for use in footwear, automotive components, wires, tubes and cables.
Use of naphthenic oils can provide improved mechanical properties – especially compared to Group I paraffinic oils. This combined with high colour stability and good solvency increases their suitability for this sector.
In the production of soft and rigid PVC, naphthenic oils can increase overall performance by increasing production speed thereby lowering overall manufacturing energy costs. They can also be used to reduce by up to 10% the need for phthalate based plasticisers, like DOP and DINP, which is beneficial from a HSE point of view.
Nynas oils are used as plasticsers for rubbers and they can be used in a variety of industrial rubbers ranging from non-polar grades such as EPDM to polymers of high polarity such as SBR.
• Fertiliser Anti-caking
Naphthenic oils are often used as anti-caking agents to prevent fertiliser granules from clumping together or forming dust. The oil is used to carry the amine anti-caking agent and is sprayed onto the granule.
The high solvency and fluid nature of naphthenic oils at low temperatures (aiding the pumpability of the oil) are two key properties that are essential in anti-caking production.
The low environmental impact of these oils is another beneficial property.
• Concrete Mould Release Agents
Release agents are used to prevent two surfaces sticking to each other by forming a film that acts as a lubricant between the surfaces. They can be used to prevent concrete, glass or metal from sticking in moulds. Naphthenic oils are particularly suited to concrete casting as they are used to dissolve fatty acids which form a soap like film when in contact with concrete and it is this film that produces the lubricating effect. Other additives can be used to prevent air bubble formation and prevent corrosion. Naphthenic oils also have a low viscosity which mean that they can be sprayed onto the mould and the product is also fluid in Winter.
