Pressure-sensitive adhesives (PSA)

Pressure-sensitive adhesives are permanently tacky, non-curing systems based on synthetic rubbers such as styrenic block copolymers (SIS, SBS, SEBS). Designed for permanent and reclosable bonding applications, they retain their tack even after cooling and provide excellent adhesion to challenging substrates.

These adhesives are widely used in transport and shipping packaging, labeling, adhesive tapes, assembly support bonding, as well as in the production of mattresses and upholstered products.

Key benefits and applications:

- Very high initial tack for immediate bond formation
- Excellent flow characteristics for optimized wet-out
- Flexible bond line to accommodate material movement
- Homogeneous and fast melting behavior for efficient processing
- Suitable for common application methods, including nozzle, roller, and spin-spray systems
