Chemical-Resistant Rubber Belts

AdobeStock_523405157_edited.jpg

Built to Resist Acids, Alkalis, and Corrosive Materials

In industries where materials are chemically aggressive — such as fertiliser, pulp, salt, or wastewater — standard rubber belts can degrade rapidly. Swelling, cracking, and hardening from acid or alkali exposure not only shorten belt life but also increase maintenance and safety risks.

Leopard Intertrade’s chemical-resistant conveyor belts are specially formulated to resist chemical attack across a wide pH range. Designed for both dry and wet applications, our belts retain tensile strength, flexibility, and abrasion resistance even under continuous exposure.

Each grade is verified according to ISO 1817, the international standard for chemical resistance in rubber. Whether your operation involves light contact with powdery fertilisers or full immersion in acidic slurries, we offer a tailored solution to ensure long-lasting, dependable performance.

Acid & Alkali Resistance

 

Covers withstand pH 2–12 environments, protecting against swelling, cracking, and degradation.

Mechanical Integrity

 

High tensile strength (≥14 MPa), excellent abrasion resistance (≤150–200 mm³), and elongation ≥300%.

Custom Formulations

 

Choose from light, moderate, or high-resistance grades depending on chemical type, concentration, and exposure conditions.
