The portfolio includes low-PCA rubber process oils that retain the performance benefits of aromatic oils in rubber and tire applications while being non-carcinogenic under the EU Dangerous Substance Directive. These products are suitable for applications requiring high aromaticity combined with low toxicity and offer a label-free alternative to highly aromatic, labeled process oils. Furthermore, H&R supplies paraffinic oils with controlled properties across various viscosities, widely used in automotive rubber components for enhanced performance. H&R has also developed renewable alternatives to fossil-based low-PCA rubber process oils suitable for NR, IR, BR, and SBR applications.
