Novares Pure

The NOVARES pure series of water-white resins provides a range of polymer compatibilities and can fulfil the requirements of a broad spectrum of applications. Hydrogenated resins are used when low odour and colour, thermal stability and excellent polymer compatibility are required. Their low molecular weight, straight linear structure and aliphatic nature lead to properties like adhesion on special surfaces, transparency in polymers and desired viscosities.

Colour- and odour-free resins with no negative health impact are increasingly in demand to meet evolving customer and regulatory requirements.

Growing demand for specialised hotmelt adhesives has led to additional requirements related to defined compatibility, softening points and thermostability. Premium NOVARES pure resins have been specifically formulated for these and many other demanding requirements and applications.

In coating formulations, the fully hydrogenated low-polar NOVARES pure resins can be used to modify alkyd resins with long and middle oil length. They improve the UV stability, chemical resistance and solid content of coating formulations.

Hydrocarbon resins are commonly used for the manufacture of plastics and to improve film properties in flexible packaging. In polar plastics like PVC, non-hydrogenated resins are compatible and function as lubricant and mechanical modification. In polyolefine-based plastics, hydrogenated resins are the first choice due to better miscibility. In BOPP (biaxially orientated PP film) compounds, the highly miscible resin NOVARES pure 1120 shows a strong impact on the crystallisation process induced by stretching and promotes transparency and gloss of the final film. NOVARES pure 1120 also extends the shelf life of packaging and preserves a product's aroma and freshness by improving the water-vapour barrier. As a result of the hydrophobic property and the filler effect of the low-molecular hydrocarbon resin in a macro molecular BOPP network, NOVARES pure 1120 reduces oxygen and moisture permeability and improves the stiffness and twist stability of a BOPP film.

NOVARES pure resins are highly compatible with aliphatic and high-saturated rubbers like NR, EPDM and HNBR. The incorporation of NOVARES pure resins improves the handling and processing properties of rubber. Due to a high saturation, the hydrogenated resins have low impact on vulcanisation properties but improve oil resistance and ageing stability of a compound. NOVARES pure resins can be considered as a special processing aid with a very low migration tendency for those rubber products with high safety requirements due to skin and food contact.
