PVC/PVG Solid Woven Conveyor Belt |
Product Features:
The product consists of solid woven fabric dipped in PVC paste and adding 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 to service in the conditions needing fire resistant and antistatic properties 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 advantages than non pressed PVC belt on impact resistance, water soaking, with longer service life, higher fastener holding.

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
Characteristics:
Anti slide caused by wetness good climbing capacity
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 |

Fire-resistance Anti-static Solid Woven Conveyor Belt For Coal Mining |
Product features
1.The belt with multi-plies solid woven structure carcass, after whole plastic fire-resistance plaster dipping, is manufactured though high temperature plastication (named PVC solid woven fire-resistance conveyor belt) or after sticking the cover of the fire-resistance rubber/plastic, vulcanizing by flat bed press (named PVG solid woven fire-resistance conveyor belt).
2.The Physical properties and safety data of PVC and PVG solid woven fire-resistance conveyor belts all equally are up to MT147-1995 standard.
Types and specifications
1. According to the longitudinal tensile strength at break whole solid woven fire-resistance conveyor belt. The product's types are divided into: 680S, 800S, 1000S, 1250S, 1400S etc., different strength grades.
2. According to the whole width of the solid woven fire-resistance conveyor belt. The product's specifications are divided into 650mm, 800mm, 1000mm, 1200mm, 1400mm etc., different width grades.
