Chemical-Resistant Rubber Belts
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.
Grade | Standard | Application | Recommended pH Range | Typical Compound | Tensile (MPa) | Abrasion (mm³) | Elongation (%) | Features & Industries |
|---|---|---|---|---|---|---|---|---|
CR-Mild | ISO 1817 | Light chemical splash / dust | 5 – 9 | SBR / NR blend | ≥14 | ≤200 | ≥350 | For dry chemical dust and mild splash areas in agro-industries. |
CR-Standard | ISO 1817 | Wet acidic/alkaline contact | 4 – 10 | SBR / EPDM | ≥14 | ≤180 | ≥350 | Ideal for fertiliser plants, wastewater systems, salt transfer. |
CR-Heavy | ISO 1817 | Continuous chemical exposure | 2 – 12 | EPDM / Neoprene | ≥14 | ≤150 | ≥350 | For harsh environments in chemical plants and pulp/sludge lines. |
Note Chemical resistance tested according to ISO 1817, involving immersion of rubber specimens in standard acid/alkali solutions at 70°C for 72 hours.
