A Manufacturer You Can Count On.

At United Polymers, we don’t just meet industry standards — we engineer every batch of spray foam to exceed them, so you can build, design, or spray, with confidence, job after job.

Why We Started...

When starting United Polymers, we saw what others overlooked — a need for spray foam that performs with precision every time. Too many contractors get frustrated with inconsistent products, wasted material, and unreliable results. We knew there had to be a better way... So we built it.

SupremeSeal™ was created to solve the real challenges professionals face on the job: foam that sprays smooth, sets right, and delivers the yields you expect — every single set. No surprises. No compromises.

Today, SupremeSeal™ is trusted by contractors and builders across North America who refuse to settle for anything less than dependable performance. We’re here to raise the bar — with products that work as hard as you do.
