Hot Melt Pressure Sensitive Adhesive
Hot melt pressure sensitive adhesive (HMPSA) is a 100 % solid, solvent-free thermoplastic that combines aggressive tack at room temperature with the ability to form an instant bond under light pressure. Applied in a molten state and cooled in seconds, it retains permanent tackiness, allowing labels, tapes, medical patches or construction membranes to be repositioned or cleanly removed without additional curing. The polymer backbone—typically styrenic block copolymers, amorphous poly-α-olefins or metallocene polyolefins—can be tuned for service temperatures from –40 °C to +150 °C, UV and plasticizer resistance, or biocompatibility, making HMPSAs indispensable in packaging, hygiene, automotive interior and wearable medical device assembly.
Description
Our Features
Since 2001, our company has focused on the research, development and production of hot melt pressure sensitive adhesive solutions. Nearly a quarter-century of specialization has given us a deep understanding of polymer design, rheology and end-use performance, enabling us to translate customer ideas into reliable, ready-to-coat HMPSA grades that run smoothly on high-speed lines and perform consistently in the field.
Our technical center is equipped with pilot reactors, high-shear mixers, rheometers, DSC, TGA and standardized peel/tack/shear stations. This comprehensive toolbox allows us to formulate styrenic block copolymer, PO and APAO based hot melt pressure sensitive adhesive systems that meet specific temperature, adhesion, aging and regulatory requirements. Whether you need ultra-removable medical tape, low-odor diaper elastic, freezer-grade label or high-shear automotive mount, we can customize color, viscosity and coat-weight window while optimizing your total applied cost.
We regard every project as a partnership: our formulators, application engineers and sales team work side-by-side with customers from concept validation to full-scale production, sharing data, trouble-shooting coating issues and adjusting formulas in real time. The result is a portfolio of field-proven HMPSA products that help clients reduce scrap, increase line speed and bring differentiated articles to market faster.
Looking forward, we remain committed to sustainable innovation-incorporating bio-based tackifiers, reducing application temperature and developing recyclable PSAs-so that our customers and the planet can enjoy the benefits of high-performance adhesion for generations to come.
