HC-5090 Key Applications

EVA-based HMA (VA 19–28%)

- Softens polyethylene segments → 15–20% longer open time, deep wetting of PE-coated carton board for stronger sealing

- Low density & high heat resistance: 5% lighter, 8–10% lower coating cost

- Blends with hydrogenated resins for FDA-compliant, low-odor food-packaging adhesives

SBS-based HMA / PSA

- Cuts melt viscosity 30% at 120 °C for high-speed, non-string spraying

- Instant tack and 20% higher peel; ideal for non-wovens, labels, low-temp tapes

- Single resin delivers both tackifying and viscosity reduction—impossible with straight C5 or C9 alone
