PVG Solid Woven Flame-resistance Conveyor Belt

PVG Solid Woven Flame-Resistant Conveyor Belt

Ultimate Safety for Underground & Hazardous Environments
Engineered to prevent fire propagation and resist static ignition, the PVG (Polyvinyl Chloride/Polyvinyl Alcohol) Solid Woven Flame-Resistant Conveyor Belt sets the global standard for safety in underground coal mines, chemical plants, and confined spaces. Its solid woven fabric core fused with PVC/PVG covers delivers unmatched flame resistance, anti-static properties, and durability under high-tension operations.

Core Safety & Performance Features

1. Fire & Flame Resistance

   • Self-Extinguishing: Meets MSHA 30 CFR §18.65, EN 14973, and AS 1330 standards.

   • Fire Propagation: Zero flame spread beyond ignition zone (ISO 340, ASTMD378).

2. Anti-Static Protection

   • Surface resistance ≤3 × 10⁹ Ω (ISO 284) – prevents spark-induced explosions.

3. Robust Solid Woven Construction

   • High-Strength Fabric Core: Tensile strength 315–2,500 kN/m (ISO 283).

   • PVG/PVC Fusion Bonding: Covers chemically fused to core – no delamination.

4. Abrasion & Impact Resistance

   • Top Cover: 3.0–12.0 mm thickness | Abrasion loss ≤100 mm³ (DIN 53516).

   • Bottom Cover: 1.5–6.0 mm | Optimized for pulley friction.

5. Chemical & Moisture Immunity

   • Resists oils, acids, alkalis, and humidity (MT/T 914-2019).

Technical Specifications

Certifications & Standards

• Global Approvals:

  • MSHA (30 CFR §18.65) – U.S. underground coal mines

  • ATEX Directive 2014/34/EU – Explosive atmospheres

Critical Applications

• Underground Coal Mining: Longwall face, drift entry, slope conveyors

• Tunneling & Subways: Fire-safe material transport in confined spaces

• Chemical/Power Plants: Hazardous zone conveying (e.g., sulfur, coal dust)

• Grain Silos & Ports: Explosion-prone environments

Competitive Advantages

✅ Zero Fire Risk:

• Passes flame retardation, antistatic, and drum friction tests (ISO 340, ISO 284).
  ✅ Longevity:

• 2–3× lifespan vs. rubber belts in high-moisture mines.
  ✅ Low Maintenance:

• Solid woven core resists elongation – no re-tensioning.
  ✅ Eco-Safe:

• Halogen-free options available (EN 50575 fire reaction class B1).
