In demanding environments such as underground coal mining, tunneling operations, and high-intensity material handling systems, conveyor belts must deliver not only strength and durability but also enhanced safety and structural stability. Our PVC/PVG solid woven conveyor belt is engineered to meet stringent international standards, offering a fully integrated woven carcass that eliminates the risk of layer separation while ensuring consistent performance under heavy loads. Constructed from high-strength polyester and cotton yarns woven into a solid structure, and impregnated (PVC) or covered (PVG) with flame-resistant compounds, this belt provides excellent resistance to impact, tearing, and abrasion. It also features inherent anti-static and flame-retardant properties, making it especially suitable for hazardous environments where fire safety is critical. With stable performance across a typical operating temperature range of -10℃ to +80℃, it is ideal for transporting coal, aggregates, and other bulk materials in confined or high-risk conditions. Compared to conventional multi-ply belts, this design offers superior durability, reduced maintenance, and enhanced safety compliance, making it a reliable choice for operations that demand both performance and peace of mind.
The PVC/PVG solid woven conveyor belt is made of a "solid woven core + PVC/PVG cover rubber" through impregnation, plasticization, and vulcanization:
High-strength polyester/cotton blended woven core, bearing tensile loads with low elongation (≤1.5% at 10% load).
Top + bottom PVC cover rubber (single side thickness ≥1.0mm), with flame-resistant and anti-static properties; suitable for ≤16° incline transport.
Top + bottom rubberized PVC cover rubber (more flexible), with better wear resistance; suitable for ≤20° incline transport.
Ensures tight bonding between core and cover rubber, avoiding layer separation under low-temperature/humid conditions.
Features and Benefits
Meets MT668-2019 standard: Alcohol combustion time ≤10s (average ≤3s), propane combustion damage length ≤1250mm, surface resistance ≤3×10⁸Ω—prevents static explosion in underground mines.
Solid woven core has longitudinal tensile strength up to 1600N/mm, bearing heavy loads; low elongation ensures stable conveying speed, no material deviation.
PVG type cover rubber has Shore abrasion ≤150mm³; solid core resists impact from falling coal/ore, reducing belt damage.
PVC/PVG cover rubber is water-resistant (water absorption ≤1.5%); suitable for underground wet mines and tunnel construction.
backed by 20M meters annual capacity, we deliver small batches on time.
Support independent customization according to your needs (e.g., belt strength, width, cover rubber type).

Q1:What is the difference between PVC and PVG solid woven conveyor belts?
A1:
The main difference lies in the rubber cover. PVC belts are made entirely of PVC and are suitable for dry conditions, while PVG belts have a PVC core with added rubber covers, making them more suitable for wet environments and heavier-duty applications. PVG belts also offer better wear resistance and longer service life.
Q2:Are PVC/PVG solid woven conveyor belts flame resistant?
A2:
Yes, PVC and PVG solid woven conveyor belts are designed with flame-retardant properties, making them suitable for underground mining applications. They comply with safety standards to reduce fire risks and improve operational safety in hazardous environments.
Q3:How long does a PVC/PVG solid woven conveyor belt last?
A3:
The lifespan typically ranges from 3 to 8 years, depending on working conditions such as load, environment (dry or wet), maintenance, and belt quality. PVG belts generally last longer than PVC belts due to their enhanced wear resistance.
Q4:How do you choose between PVC and PVG conveyor belts?
A4:
Choose PVC belts for dry, less demanding environments with lighter loads. Opt for PVG belts when operating in wet conditions, handling heavier materials, or requiring higher durability and longer service life. The choice should also consider safety requirements and budget.
