| CYROVU® HP2 is an impact-modified acrylic-based multipolymer for molding applications. Major use is for point-of-purchase displays. Typical applications include display dispenser, brochure card holders, magazine holders and signage. The polymer offers a balance of great appearance and rough and tumble durability coupled with attractive economics. The material has found many uses in the Display Industry when strength and clarity are required. The material can be decorated by a wide variety of techniques including: silk screening, hot stamping, pressure sensitive labels, pad printing and metalizing. The product is readily adaptable to tooling designed for styrene, ABS or polycarbonate. Parts made from CYROVU® HP compound can be solvent bonded, thermal-bonded and ultrasonic or spin-welded.&& |
