Q1: What are the key processing advantages of WHT-6232 compared to conventional aromatic TPUs?
A: WHT-6232 offers improved melt stability and reduced extrusion pressure during processing, supporting smoother operation in film casting, calendering, and blown-film applications. Its optimized rheology allows for better dimensional control and surface finish without requiring major equipment modifications.
Q2: Is WHT-6232 suitable for applications requiring good low-temperature flexibility and abrasion resistance?
A: Yes — WHT-6232 delivers balanced elastomeric performance, including retained flexibility down to approximately −30 °C and robust resistance to mechanical wear, making it well-suited for demanding flexible packaging films, protective coatings, and technical textile laminates.
Q3: How does WHT-6232 perform in terms of adhesion to common substrates like PET, PA, and aluminum foil?
A: WHT-6232 exhibits strong inherent adhesion to polyester (PET), polyamide (PA), and metallized surfaces, often eliminating or reducing the need for primers in lamination processes. Adhesion strength can be further enhanced through standard corona or plasma pretreatment.
Q4: Can WHT-6232 be used in solvent-based or hot-melt adhesive formulations?
A: WHT-6232 is compatible with common organic solvents such as MEK, toluene, and THF, and is frequently employed in solvent-borne adhesive systems. It also functions effectively in thermoplastic hot-melt formulations where clarity, toughness, and thermal reversibility are required.
