Application
1. PSA & HMA: acts as a tackifying resin, instantly boosting peel strength and heat resistance.
2. Plastic modification: processing aid for PVC/TPU extrusion & injection, lowering melt temperature, improving flow and stiffness.
3. Rubber tire: tread moisture-resistant modifier that enhances wet grip and reduces heat build-up; also reinforces TPE, wire coatings, ionic elastomers.
4. Coatings & specialty molding: increases gloss, abrasion resistance and drying speed while serving as a reinforcing filler.
