Jonson Fire Resistant belting has a proven track record of superior service in coal mining and other similar applications where the high, continuous output depends largely on the performance and reliability of the belt. Jonson Fire Resistant, designed primarily for use in underground and other potentially hazardous situations, meets and in many cases, exceeds the fire-resistance and anti-static requirements of all worldwide safety standards. Through its PVC compounds, customizable cover thickness and its solid woven carcass, making the belt ideal for conveying coal, potash, phosphate, fertilizer, clay, gypsum and salt. It is also suited for use in the timber industry.

The table shows nominal figures for minimum warp & weft breaking strengths, belt thickness & weight for a selection of belt types, based on 1mm x 1mm PVC covers on either side. For every additional 1mm PVC, add 1.25kg/sq.mtr for PVC covers. Nominal values with 1+1 PVC covers.
Widely used in fiery mines i.e. underground coal mines, power stations, chemical and metallurgy industries
Complete in-house manufacturing - from yarn preparation, fabric weaving, compound mixing to belt finishing - to ensure total process and quality control at each step of manufacturing activity. Each belting roll is tested for physical, fire retardant and anti static properties - one of the few manufacturers who can claim to do 100% tests on all belts. One of the best conveyor belting test facilities where a fully equipped test laboratory conducts test of all incoming yarns and chemicals, as well as on finished product, including tests for flame, static conductivity drum-friction, limited oxygen index, etc. In addition, physical tests like tensile strength, elongation, tear, adhesion, fastener holding, trough ability etc. are also conducted as routine tests.
