The First Technical Diagnostic and Troubleshooting Simulator for Polyurethane Systems
Sepehr Donya has developed this analytical pathway to turn real production-line symptoms into reliable technical decisions;
a place where the problem is not only observed, but also simulated and analyzed.
Please note that these results are estimated analytical outputs.

When PUR/PIR Selection Cannot Be Decided by Density Alone
Thermal behavior, reaction time, and application conditions define the real path for system selection.
When Foam-to-Surface Bonding Is Not Stable: No Adhesion or Weak Adhesion
Surface temperature, moisture, facer type, and the reaction window determine interfacial bond quality.
The Root of Density Variation: When Output Quality Is Not Repeatable Between Batches
Mixing, temperature, moisture, and reaction ratio can change the cellular structure.
Polyurethane Foam Shrinkage and Dimensional Change: When Foam Does Not Retain Its Shape After Curing
Demolding, mold temperature, density, and internal network stress determine dimensional stability.
When Insulation Performance Cannot Be Explained by Thickness Alone
Thermal stability, cell structure, and surface adhesion can change the final insulation result.

Why Sepehr Donya?
Selecting Polyurethane Raw Materials Is More Than Buying a Chemical
In industrial production, the final quality of foam does not depend only on the name of the raw material; the technical requirements of the production line, equipment type, target density, reaction times, adhesion, and dimensional stability also have a direct impact on the purchasing decision. Before an order is placed, Sepehr Donya helps make the selection process clearer and lower-risk for manufacturers.
Application Review Before Recommendation
The system recommendation is based on application, production conditions, and the expected result — not simply on warehouse availability.
Technical Experience in Formulation
From polyurethane foam systems to industrial projects,
material selection is guided by real-world performance.
Support After Selection
When needed, technical follow-up, production-path adjustment, and
review of quality-verification samples are available.
The result for you: more reliable purchasing, lower risk of production downtime, and more accurate selection of polyurethane raw materials.

Common Paths for Purchasing and System Selection
High-Demand Solutions for Polyurethane Manufacturers
If you are selecting raw materials, optimizing a formulation, or reducing production risk, these three paths are usually the starting point for technical and purchasing decisions in polyurethane projects.
Quick Selection Guide
To Select Polyurethane Raw Materials, Start with the Application — Not Just the Product Name
When purchasing polyurethane raw materials, the right path becomes clear when the application, production challenge, and next action are considered together. This guide helps you quickly identify which specialized page to visit or when to submit a technical brief.
01
What Is Your Application?
02
What Is the Main Production-Line Challenge?
- Density or quality variation between batches
- Weak adhesion to the surface or sheet
- Shrinkage, dimensional change, or low stability
- Unsuitable reaction time during production
- Need to reduce energy loss or improve insulation
- Need for a more accurate formulation for existing equipment
