Application

The combination of adhesion to difficult substrates and low melting temperature enables thermoplastic grades of CAPA^® to be used in speciality hot melt adhesive applications. In particular, the low melting point and low melt viscosity combine to make CAPA^® hot melts suitable for use with temperature sensitive substrates.

The growth in demand for reactive hot melts has also highlighted the versatility of CAPA^® products where the functionality and molecular weights can be varied to maximise performance. Typical end uses are:

Shoe Counters
Reactive Hot Melts for Non-wovens
Binder for Non-wovens
Scatter Coat Interlining Adhesives

Excellent adhesion to leather and other difficult substrates.
Low temperature activation.
Reactivated by heat, no solvent needed.
Biodegradable.
Non-toxic.
Crystalline, rigid polymer with high elongation.
Polar polyester easily pigmented or coloured.
Compatible with wide range of polymers.
Hydroxyl groups allow sites for reaction.
Low melt viscosity allows ease of application and penetration into substrate.
Low Tg gives good low temperature performance.
