3M Double Coated Tissue Tape 9448HK
High-strength bonding for electronics
3M™ 9448HK is a high-adhesion, general-purpose double-sided tape with a non-woven tissue carrier and modified acrylic adhesive. It features superior initial tack, excellent shear holding, and strong bonding to low-surface-energy (LSE) materials (e.g., PP, PE, rubber) and rough surfaces. Optimized for industrial die-cutting, lamination, and assembly, with good temperature and UV resistance.
