Typical Acid Strengths in Semiconductors

HDPE, polypropylene and PVDF each handle sulfuric acid differently. See the compatibility chart for every rating.

93–98%

Above the range of our compatibility database. Call us before storing 93–98% acid so we can review your application.

75–93%

PVDF rated Excellent and HDPE rated Good. Polypropylene drops to Fair. Use PVDF fittings and Viton® gaskets.

Every style is listed with live sizes, dimensions and prices.

Kynar® PVDF, rated Excellent for sulfuric acid to 93%.

PVDF with built-in secondary containment.

What to consider

Send the acid concentration, temperature, volume and fittings you need. We’ll match the resin, SG rating and gaskets.

96% is above our database range: call us before storing 93–98% acid so we can review your application.
Why PVDF: Kynar® PVDF is pure in its natural state and is rated Excellent for sulfuric acid to 93%.
Fittings: PVDF fittings and Viton® gaskets for concentrated acid.
More high-purity chemicals: see our PVDF semiconductor tanks for hydrofluoric, nitric and hydrochloric acid.
