        # Managing Volatile Loss in High-Temperature Applications

        

**Topic:** Technical

        

Your products look great when they leave the factory, but after a week in a hot warehouse, they've shrunk and become stiff. Your plasticizer is literally vanishing into thin air.

        
---
## Problem

Volatile loss occurs when low-molecular-weight components in your formulation evaporate at service temperatures. This is a major issue for automotive interiors, outdoor cables, and industrial gadgets.

---

        
---
## Likely cause

This issue often stems from inconsistent compounding temperatures, inferior raw material purity, or unbalanced stabilizer ratios within the formulation matrix.

---

        
---
## Corrective direction

The solution is to move to high-molecular-weight plasticizers like NBT DINP or DIDP, which have significantly lower vapor pressure than DOP. Additionally, using NBT Diamond Grade CPW, which is stripped of low-boiling-point hydrocarbons, ensures that your formulation stays intact even under prolonged heat exposure.

          ## Frequently Asked Questions

          
### Does volatile loss affect the smell?

Yes, high volatility is the primary cause of strong chemical odors in finished products.

### Is there a test for this?

Yes, the Activated Carbon test (ISO 176) is the standard for measuring plasticizer volatility.
