Chemical-Resistant Sealing for Fertilizer and Agrochemical Plants

Fertilizer and agrochemical production handles some of the most aggressive process chemistry in industry — ammonia, urea solutions, phosphoric and sulphuric acid — and a sealing material that isn’t genuinely chemically compatible fails quickly, often with hazardous consequences.

Pump and valve shaft sealing

Pure PTFE Gland Packing resists the full pH 0–14 range these processes span, making it the default choice for shaft seals on ammonia, acid and urea-handling equipment.

Flange and vessel gaskets

PTFE Joint Sealant conforms to irregular or lined vessel flanges common in fertilizer processing, while Non-Asbestos Jointing Sheet covers standard flange duty elsewhere in the plant.

Machined chemical-resistant components

PTFE Sheets and PTFE Rods machine into linings, seals and bushes for direct contact with the most aggressive process streams.

Frequently asked questions

Is ammonia service different from other chemical sealing? Yes — ammonia specifically attacks many ordinary yarns and elastomers; PTFE’s inertness makes it a safe default where ammonia exposure is likely.

Can the same PTFE grade handle both acid and alkali lines in the same plant? Yes — PTFE’s chemical resistance spans the full pH range, so the same grade typically works across both without needing separate specifications.
