Product Details
  • Characteristics:

  • -Preventing slide when conveying wet material with slope.
    -Low-temperature resistant.
    -Good elasticity, anti-impact.
    -Low elongation at rated load ,suitable for long distance conveying.
    -Tear resistant, good flexing capacity.
    -Long service life.


  • Product Features:

  • The product consists of solid woven fabric dipped in PVC paste and added PVC or PVG cover which are combined together by vulcanizing. The belt has good flame-resistant and anti-static properties, with high tensile strength in proportion to weight, good integrity and no delimitation, excellent impact and rip resistance. The belt is much suitable for the service in the conditions needing fire resistant and antistatic properties such as coal mines, power stations, chemical and metallurgy industries.
    Note: The following standards are usually applied: DIN22109,AS4606,BS3289,BC158
    Classification of solid woven belt: PVC stands for the solid woven belt with PVC cover.
    Non pressed PVC type is suitable for applications in dry conditions at a slope angle of no greater than 16 degrees. The belt is non-pressed with cover no more than 0.8mm.
    Pressed PVC type, both top and bottom covers are PVC. Thickness of each side can be up to 4mm. The belt has much more excellent than non-pressed PVC belt in impact resistance, water soaking, and with longer service life, higher fastener holding. Widely 


  • Features:

  • ·  Low stretch 
    ·  Low maintenance 
    ·  Anti-static 
    ·  Flexible 
    ·  Lightweight 
    ·  Impervious to moisture, acids, oils, gases, sunlight 
    ·  Excellent fastener holding 
    ·  Excellent resistance to tearing, peeling and impact 
    ·  Endless belt splicing 
    ·  Special wear resistant edge design   


    PVG stands for the solid woven belt with PVG cover (nitrile rubber)
    PVG type is covered with covers mainly composed of rubber, which further improves the troughability, resistance to wetness and slip, resistance to low temperature, elongation and wear resistance of the belt. Both top and bottom cover are PVG, the belt can be used to carry materials mixing some water at the slope no more than 20 degree,elongate life of belt
