TuftecTM

Hydrogenated Styrenic Thermoplastic Eastomer (SEBS) Tuftec™ H1221

Asahi Kasei Tuftec™ H1221 is specially designed as a modifier to increase flexibility of polypropylene (PP). Its excellent compatibility makes H1221 ultra-finely dispersed into PP. PP and H1221 blends provide transparent PP sheets and films with excellent flexibility and resistance to hazing or whitening on bending. The excellent adhesion is suitable for the use of adhesive layer of protective films with hot-melt and pressure sensitive characteristics. H1221 meets USP Class Ⅵ standards. It may be used for medical applications after a special agreement with Asahi Kasei.

By blending Tuftec™ H1221 and H1062, transparent PP compound with excellent low-temperature brittleness resistance can be obtained.

Tuftec™ H1221 shows strong adhesion property to PMMA plate, and can be co-extruded with PP.

＜Evaluation Process＞
Adherend: PET film with 50µm thickness
Adhesive layer: Approx. 10µm thickness (Dried after solution coating)
Adhesion temp.:180 deg. C, Peeling temp.: 23 deg. C
Sample: 20mm width, Peeling speed: 300mm/min

The viscosity change of PP can be moderated by adding Tuftec™ H1221
