Petrotape (Pty) Ltd is a supplier of adhesive tapes, pipe wrappings and associated products in Southern Africa. Through a combination of manufacturing, converting, importing and local suppliers, we are able to supply a wide range of pressure sensitive adhesive tapes and their non-adhesive counterparts. Development of specialised adhesive coatings for customer-specific applications is our fastest growing division. Petrotape (Pty) Ltd began in July of 1982 as a manufacturer of petrolatum pipe wrapping tapes and associated products such as mastics and primers. The company had it's small factory situated in Booysens Reserve, Johannesburg, South Africa. Within two years (1984) Petrotape expanded into the adhesive coating business and began to manufacture general purpose insulation tape. Shortly thereafter the product range increased to include low tack protection tapes and joining tapes. By 1988, the company was also converting and distributing PVC tapes and a few speciality products. It was now necessary to move in to larger premises and so the current factory on the same block was custom built. By 1990 there were four "coating-type" machines as well as slitters, rewinders and some speciality custom-made machinery. The mid 1990's saw a change in tactics with the company now concentrating on custom-made adhesive coated products. The pipe wrappings and tapes however continue to dominate our production as the company continues to expand both it's product range and customer base. With a dedicated staff of just under twenty at the Johannesburg branch, Petrotape is able to give customers the personal attention and service that tends to become lost in the larger organisations. We value all tape and related enquiries as this enables us to increase our knowledge base and help our customers obtain those "hard to find" products. We trust that your experience dealing with us is a pleasurable one and should this not be the case, please let us know as we are always looking for ways to improve.

Woven Wire Mesh by MESHCAPE TRADING has been involved in the South African market since 1905. All materials are woven from wire as thick as 1,6 diameter down to those finer than a human hair of 0,016 diameter.Steel: Spring Steel, Bright and Galvanised Mild Steels.Stainless Steel: Chromium Steel, Nickel Chromium Steel, Nickel Chromium Molybdenum Steel, Heat Resisting Steel.Non-Ferrous Metal: Aluminium, Nickel, MONEL-Metal, Phosphor Bronze, Brass, Copper.Special Materials: Titanium, Hastelloy and many others.The more popular wire and woven wire meshes are kept in stock for use whilst the more exotic would be ordered and manufactured for specific customer requirements.State-of-the-art equipment and a team of qualified experts manufacture wire screens, wire mesh and wire mesh products suitable for all applications.Standard rolls, roll sections, sheets with fixed dimensions, hooked screens, strips, discs, fabricated parts, filter candles discs, cones, plates, round sieves, extruder screens and many others are manufactured by the following process: Cutting, cutting into lengths, bending, stretching, cleaning, plasma welding, welding, soldering, punching, stamping, compressing, forming, and many others.Whether in large quantities or small we will supply you with what you require.In addition to our complete range of Woven Wire Screening we offer Dewco (Sweco) machines and spares, expanded metal, perforated materials, Vee (wedge) wire, Welded Mesh and Wire Conveyor Belts to compliment our supply to the individual markets. In today's world of high quality plastics to replace both ferrous and non-ferrous material is a daily occurrence. High quality plastics in the form of polyurethane elastomers was introduced to the screening world during the mid-fifties and has since become recognised as one of the accepted mediums from which to manufacture screening surfaces. Polyurethane's are synthesised according to the isocyanate addition process. Polyurethane's as a screening surface can lead to certain advantages when the application is appraised correctly. However, there are also disadvantages that should not be overlooked.  ADVANTAGES:Long Life: Correctly selected polyurethane's can have a long life when screening most materials. In addition it is immune to most corrosive materials.  Improved Screening Efficiency: At ambient temperatures polyurethane's exhibit the characteristic elasticity of rubber. It is the property that allows the aggregate being screened more 'bounce' thereby presenting tit to the apertures more frequently. This phenomem fulfills both laws governing the theory of screening.  Minimise Downtime: The long life time described above reduces the frequency of unscheduled stoppages due to the screening surface failure. Noise Reduction: Polyurethane's, due to their rubber like characteristics, absorb feed energy impact and reduce noise levels from between five and eight decibels. High Initial Cost: Polyurethane's used for screening surfaces have tensile strengths from 20 to 50 MPa. This necessitates an increase in cross sectional area in the construction of polyurethane screening media. In addition, polyurethane's used in the manufacture of screening surfaces are nor suitable for large unsupported areas. The addition of steel support frames is therefore normally required either internally or externally or a combination of both. Polyurethane's are manufactured from high cost materials when compared with 'Vibro' spring steel and this, combined with he additional materials described above, places the initial cost of installing polyurethane at least five times greater than the equivalent 'Vibro' screen cloth.Open Area: Due to the increase in cross sectional area described above, the resultant number of apertures for any given length, when compared to woven wire screencloths, is reduced.Aggregate Sizing: The high cost of polyurethane screening surfaces can restrict the range and versatility of screening normally available by changing woven wire screencloths on vibrating machines.Operating Temperature Range: Polyurethane's are designed to operate at ambient temperatures, this is due to the chemical chain that makes the resultant material, in general most polyurethane's will operate up to 800C before undergoing a structural change in their chemical make-up. This change normally results in a major deterioration in the quality of the polyurethane. If an application exists where ambient will be exceeded, careful consideration should be given to the type of polyurethane used.Note: Due consideration should be given to the basic laws governing screening and screening efficiency when deciding to change from woven wire screens to polyurethane screening surfaces.It has been shown in most cases that screening efficiency is reduced by up to 30 %, resulting in lower throughput and higher recirculation loads. The end result is higher maintenance costs for lower throughput and the need to run the Plant for additional hours to process the required tonnages, resulting in an unacceptably high cost per tonne. Whilst the actual cost for the screening surface is reduced, this reduction does not in any way compensate for the additional costs incurred
