Polyurethane formulation guides
How to replace TCPP in polyurethane foam: a halogen-free reactive approach
Why TCPP replacement is a system-level reformulation, what to test when removing it, and how halogen-free reactive additives target ASTM E84, UL 723 and CAN/ULC-S102.
How can bio-polyols raise renewable content without sacrificing green strength?
Why bio-polyol swaps slow green strength and demold, and how reactive, high-functionality soy modifiers protect tear, tensile and elongation.
What is TCPP and why is it being phased out?
A practical guide to the regulatory and toxicology pressures on chlorinated phosphate flame retardants — and what to use instead.
R-Value vs K-Factor: a formulator's guide to PIR insulation
How thermal conductivity, blowing-agent choice, cell structure, and aging combine to set the long-term thermal resistance of polyiso boardstock.
Bio-based polyols 101: from soy oil to reactive OH
Epoxidation, ring-opening, and the difference between a 'natural-oil polyol' and a true reactive primary-hydroxyl bio-polyol.
Fire, smoke & toxicity testing for polyurethane foams
ASTM E84, UL 723, CAN/ULC-S102, NFPA 286 and NBS smoke chamber — what each test measures and how PIR formulators meet them.
Polyurethane glossary: 60 terms every formulator should know
From A-side and B-side to zwitterion catalysts — a working vocabulary for the polyurethane industry.
