Potassium Cyanide Resistance of PVC Flexible

Is PVC Flexible compatible with Potassium Cyanide?

Compatibility Rating

At 20°C
A
Excellent
Excellent resistance - recommended for continuous use
At 50°C
D
Poor
Not recommended - significant degradation expected

Why is PVC Flexible resistant to Potassium Cyanide?

PVC Flexible shows excellent resistance to Potassium Cyanide due to similar chemistry to rigid PVC but with plasticizers that can be extracted by some solvents.

⚠️ When NOT to use PVC Flexible

Avoid using PVC (Flexible/Plasticized) with the same solvents as rigid PVC, plus any chemical that extracts plasticizers. Generally less resistant than rigid PVC.
