Cable profiles

All cable lengths were unfaired except at 330 m (faired, drag coefficient was 0.1). Computed by extrapolation of data using computer simulation of cable profiles. 

Chem. Descrip. Aluminum hydroxide CAS 21645-51-2 EINECS/ELINCS 244-492-7 Uses Eiller, flame retardant for polyester resins (SMC, BMC, laminates), epoxy and acrylic resins, crosslinked elastomers (conveyor belts, cables, profiles, molded parts), latexes (wall paper, carpetbacking), thermoplastics and thermoplastic elastomers (PP, PE and copolymers, EVA), PVC... 

Plastic coatings are applied in different forms and shapes on many different products, such as wire, cable, profiles (plastics, wood, aluminum, etc.), films/foils (plastics, aluminum, steel, paper, etc.), rope, and so on. Certain coatings only require snug fits, whereas others require excellent adhesion, usually necessitating cleaning, priming, and/or heating substrates. 

For flexible sheeting, as single ply roofing use, PVC and ethylene-propylene-diene monomer (EPDM) are expected to be the main polymers used. For wall and floor coverings PVC is still expected to continue to dominate the construction market. PVC will be the main plastic used for pipe and conduit, wire and cable, profiles and flooring applications, while EPS will be mostly used in insulation. 

Recommended for products flexible PVC-tubes, cables, profiles, sheets ... 

The amount of plasticizer added to the polymer in question varies, depending on the magnitude of the effect required. For example, a small addition of plasticizer may be made simply to improve the workabiUty of the polymer melt. This contrasts with larger additions made with the specific intention of completely transforming the properties of the product. For example, PVC without a plasticizer, ie, unplasticized PVC (PVC-U), is used in appHcations such as pipes and window profiles with plasticizer added, articles such as PVC food film, PVC cable insulation, and sheathing and PVC floorings are formed. 

Woddwide consumption of plasticizers is estimated at 3.5 x 10 t (31), and is of the order of 1 million tons in Western Europe (Eig. 7 Table 4). The distribution of plasticizers into various appHcations is as foUows 27%, wine and cable covering 23%, extmsion/profile 17%, film and sheet 13%, coated fabrics 12%, wall covering and 8%, undersealing/coating. 

The main uses of EPM of EPDM are in automotive appHcations as profiles, (radiator) hoses, and seals in building and constmction as profiles, roofing foil, and seals in cable and wke as cable insulation and jacketing and in appHances as a wide variety of mostiy molded articles. 

Unfortunately, not all distortions of acquired data result in a low-level alert. Damaged or defective cables or transducers can result in a high level of low-frequency vibration. As a result, the low-level alert will not detect this form of bad data. However, the vibration signature will clearly display the abnormal profile that is associated with these problems. 

In most cases, a defective cable or transducer generates a signature that contains a ski-slope profile, which begins at the lowest visible frequency and drops rapidly to the noise floor of the signature. If this profile is generated by defective components, it will not contain any of the normal rotational frequencies generated by the machine-train. 

With the exception of mechanical rub, defective cables and transducers are the only sources of this ski-slope profile. When mechanical rub is present, the ski slope will also contain the normal rotational frequencies generated by the machine-train. In some cases, it is necessary to turn off the auto-scale function in order to see the rotational frequencies, but they will be evident. If no rotational components are present, the cable and transducer should be replaced. 

Wire and cable applications and extrusion profiles, e.g., window seals and car door seals, probably form the major applications for EPM and EPDM rubber, although they are also used in a wide variety of other extrusion and moulding applications. Washing machine door seals moulded from EPDM are starting to replace NR as washer/dryers are becoming more common.
