This guide provides information on the chemical resistance of flexible metallic conduit components, specifically PVC, PU, and Type LTXE thermoplastic rubber jackets. It helps determine compatibility with various chemicals.

Chemical resistance for PVC and PU is rated using a scale: A (Excellent to Good), B (Good to Fair), C (Fair to Limited), and D (Unsatisfactory).

No, the information is a guideline only, and no guarantee is implied. Results are based on controlled laboratory tests, not installed end-product applications.

ABB recommends exposing and observing samples in actual service conditions for extreme or unusual situations to verify chemical resistance.

After 7 days at 60 °C, the LTXE jacket retains 90% tensile strength and 98% elongation. At 100 °C for 4 days, it retains 66% tensile strength and 70% elongation.

After 72 hours at 100 °C, the LTXE thermoplastic rubber jacket retains 40% tensile strength and 35% elongation, with a 17% volume increase.

After 72 hours at 100 °C, the LTXE thermoplastic rubber jacket retains 50% tensile strength and 50% elongation, with a 32% volume increase.

After 72 hours at 100 °C, the LTXE thermoplastic rubber jacket retains 95% tensile strength and 90% elongation, with a 2% volume increase.

PVC has a "B" rating (Good to Fair) for resistance to Acetic Acid 10%.

PU has a "D" rating (Unsatisfactory) for resistance to Acetone.
