Latest Patents
Hanaoka's latest patents include a surface protection sheet and a pressure-sensitive adhesive tape. The surface protection sheet is designed to be less susceptible to breaking and tearing during adherend processing, allowing for easy removal. It consists of a substrate and a pressure-sensitive adhesive (PSA) layer, with the base polymer of the PSA layer having a glass transition temperature of -50°C or higher. This innovative sheet boasts at least 200% elongation at break in both machine and transverse directions.
The pressure-sensitive adhesive tape developed by Hanaoka utilizes an alternative compound to bis(2-ethylhexyl) phthalate (DOP) and dibutyl phthalate (DBP), ensuring compliance with REACH regulations. This tape features a poly(vinyl chloride) substrate and a pressure-sensitive adhesive layer, which is designed for excellent tackiness and unwinding performance. The tape contains 10 to 40 percent by weight of bis(2-ethylhexyl) terephthalate and is engineered to have specific unwinding forces at varying tensile speeds.
