Published
May 7, 2026
As spray polyurethane manufacturers work to balance sustainability, cost, and performance, this versatile additive is gaining renewed attention.
Why Trans-DCE for Foam Blowing Agent Formulations?
Trans-1,2-dichloroethylene (Trans-DCE) is an effective co-blowing agent that enhances polymer foam formulations when used in combination with primary blowing agents. Featuring zero Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP), Trans-DCE supports the development of high-performance, low-GWP foam technologies to help manufacturers:
- Improves thermal performance
- Improves production process efficiencies
- Reduces overall formulation costs
Advancing Polymer Foam and Blowing Agent Technologies
Trans-DCE is an ideal additive for major systems including:
- Polyurethane (PU)
- Extruded Polystyrene (XPS)
- Polyethylene (PE)
- Polypropylene (PP)
- Polystyrene (PS)
Key Benefits of Trans-DCE in Foam Systems
Enhanced Foam Structure and Performance
- Promotes uniform cell nucleation and finer foam structure
- Reduces defects such as voids and irregular cells
- Improves thermal resistivity, resulting in a higher R-value
Cost Optimization
- Enables greater use of cost-effective hydrocarbon blowing agents
- Reduces reliance on higher-cost components and additives
- Improves blowing-agent efficiency and formulation economics
Improved Processing Efficiency
- Enhances compatibility between blowing agents and polymer systems
- Reduces melt viscosity for smoother extrusion or mixing
- Improves processing stability and production throughput
Environmental Compliance
- Zero Ozone Depletion Potential (ODP)
- Zero Global Warming Potential (GWP)
- Supports low-GWP blowing-agent formulations
Improved Fire Performance
- Helps suppress flame spread in foam
- Reduces smoke generation during combustion
- May reduce reliance on additional flame-retardant additives
Why Trans-DCE Matters for Modern Foam Formulations
Trans-DCE is a strategic enabler that enhances performance, safety, regulatory compliance, and cost competitiveness in modern foam formulations.
