The chemical industry needs belts that withstand continuous exposure to acids, bases, solvents and aggressive compounds without degrading. A conventional belt in a chemical environment deteriorates rapidly, causing stoppages, contamination and high replacement costs.
At NFP Industrial we supply rubber conveyor belts from Zhejiang Fuda Rubber Co., Ltd. with chemical-resistant covers, and lightweight belts from Kunming Conveyor Belt with anti-corrosion features for in-plant handling processes.
Chemical-resistant rubber belts (Fuda)
Special cover tested under accelerated ageing (50 °C × 96h) with the following results:
| Class | Solution | Concentration | Volume change | Strength change |
|---|---|---|---|---|
| A1 | HCl (hydrochloric acid) | 18% | ≥ 10% | ≤ 10% |
| A2 | H₂SO₄ (sulphuric acid) | 50% | ≥ 10% | ≤ 10% |
| A3 | NaOH (sodium hydroxide) | 48% | > 10% | < 10% |
Applications: chemical plants, fertiliser manufacturers, paper mills, water treatment facilities.
Acid-resistant PVC/PU belts (KMB)
For handling packaged chemicals or in environments with aggressive vapours. Models with CR (cold resistant) feature for cold storage rooms for chemical products. The KMB PU range offers lower porosity than PVC, reducing absorption of aggressive compounds and making it easier to clean between batches.
