Crystalline Hot-melt Type Nichigo-POLYESTER™
- Crystalline Hot-melt Type
-
Crystalline polyester resins possessing a high level of structural cohesion, and which are resistant to dissolution in organic solvents. These resins display excellent adhesion with base materials including polyester films, vinyl chloride resins, metals, and fibers. They are ideal for use as hot-melt adhesives and hot-melt extrusion coatings.
Applications & Characteristics
- Adhesives for flat cables
- adhesive interlinings
- fiber adhesive treatments
- coatings for extruded metals
- sealants for paper containers
- adhesives for combustion filters
