Rubber and oils have been joined at the hip since the conception of the material category. Once coined as ‘extender’ oil because it simply permitted less rubber to be used in a finished article. Not much has changed until now, with the introduction of PureNova™ process oils.
Delivering performance, sustainability and processability simultaneously positions PureNova as the option for modern development. Paraffin oils suited for EPDM, natural rubber or any low-polarity rubber across application categories.
- Natural Rubber (NR)
- Butyl Rubber (IIR)
- Polybutadiene (BR)
- Styrene-Butadiene Rubber (SBR)
PureNova supports carbon neutrality targets.
Applications that specify thermoset compounds generally have very little margin for error – tires, gasket, hoses all perform important functions. Changing these materials, even in pursuit of GHG reductions, create fundamentally challenging problems. Replacing a paraffin oil with PureNova simplifies a transition to sustainable content.
One kilogram of an EPDM compound that contains 50 or 70% PureNova process oil provides a 38% and 66% reduction in GHG emissions as compared to a conventional paraffinic oil. Substituting one hydrocarbon for another downplays manufacturing risk, and yet has significant impact.
Maintain specifications even longer
PureNova is advantaged by what it does not contain – a broad distribution of molecular weights and impurities. Low and high molecular weight ‘tails’ are often attributed to off-gassing, fogging, blooming and the like. PureNova grades, but virtue of their purity remove those traits from your compound. Further, eliminating any volatile species means that properties are maintained through serviceable life, ensuring that the oil continues to deliver performance over time.
Compared to Competitive grades with comparable viscosity, PureNova do not observe any volatility until 400°C or greater. Mass retention will give your compounds an edge in performance in even the most challenging conditions.
Efficiencies gained to production
Purity and structural characteristics of PureNova have demonstrated efficiencies in manufacturing:
- Lower energy consumed in compounding
- Reduced cure times at a given temperature
- Reduced oil loadings to meet specifications
- Reduced level of peroxide curative
Frequently Asked Questions
We welcome the chance to have this conversation about the GHG emissions of your product. Using published data and our Life Cycle Analysis (LCA) for PureNova we can estimate a net difference of carbon emissions on your product, which can, in turn, be communicated to your customer. This level of transparency may not be typical, but we believe that it is essential to achieving your carbon neutrality pledge.
PureNova is a pure, non-polar paraffin molecule, and consequently can provide superior compatibility in non-polar polymers. For example, styrenic-block-copolymers, polyolefins and polyolefin elastomers, EPDM, and natural rubber.
Similarly, PureNova is compatible with while oils, silicone oils, triglycerides, and many other oils that could be used in processing. You can confidently drop it into existing manufacturing setting knowing that it will not create a cumbersome changeover.
Absolutely not. PureNova grades have demonstrated resilience against heat, UV and time without any measurable property loss. Biodegradability is initiated under very specific set of conditions, and not one that a performance plastic is likely to encounter during its serviceable life. You can be confident that including PureNova into your formulations will deliver unparalleled stability in the most arduous of conditions.
