Specialty Plasticizers for Solvent-Based Formulations Thermoplastic polyurethane resins for flow control, flexibility and clarity
US Polymers-Accurez offers a range of high-performance plasticizers designed for solvent-based industrial systems. Our Reze‑Lastic™ thermoplastic polyurethanes deliver balanced softness, processability and mechanical performance in coatings, adhesives and inks. USPA resins are ideal for applications demanding strong film integrity and impact resistance without compromising clarity or viscosity. Contact us today for more information.
Supporting Flexibility in Industrial Applications
Thermoplastic polyurethane plasticizers are commonly used to modify the mechanical and rheological properties of performance coatings and adhesives. Reze‑Lastic™ plasticizers enhance flexibility, improve flow and reduce brittleness in systems subjected to stress, impact or frequent handling. Common use cases include protective overcoats, printing inks, flexible packaging films and multi-component adhesive systems.
Key Benefits of USPA Plasticizers
- Excellent clarity and softness for transparent systems
- Improved film flexibility and durability
- Controlled viscosity and flow for easier processing
- Compatible with a wide range of polyurethane systems
- Available in aromatic and aliphatic variants for tailored performance
Solvent Aromatic Plasticizers
Soft, plasticizing and non-migrating Polyurethane resins. Fully soluble in alcohol and exhibit excellent heat, oil, fat, grease and moisture resistance while promoting solvent release in nitrocellulose-based surface print applications.
