Benzoflex® 352 for Hot-Melt Adhesives

Technical Advantages of Benzoflex® 352 for Hot-Melt Adhesives

Without proper plasticization, HMAs can become brittle, difficult to process, or exhibit weak adhesion in nonporous or flexible substrates. Traditional liquid plasticizers lower Tg (glass transition temperature) but can weaken cohesive strength. Solid plasticizers like Benzoflex® 352 bridge this gap by delivering flexibility while maintaining structural integrity. Benzoflex® 352 offers the following technical advantages for hot-melt adhesive formulations. 

 

Hot-Melt Adhesive Applications

Benzoflex® 352 improves performance in multiple hot-melt adhesive applications, including:

 

Comparison to Alternative Plasticizers

Benzoflex® 352 offers a safer, higher-performing replacement compared to dicyclohexyl phthalate or glycerol tribenzoate with broader compatibility and improved handling properties.

Conclusion

For formulators looking to improve hot-melt adhesive performance, Benzoflex® 352 provides a unique balance of fast set times, strong cohesive strength, extended open time, and substrate compatibility. Its solid-state characteristics make it a superior alternative to liquid plasticizers, ensuring adhesives are both efficient to process and reliable in service.
