Rapra sponsors PACE 2004.PACE 2004 (Polymers in Aggressive and Corrosive corrosive /cor·ro·sive/ (kor-o´siv) producing gradual destruction, as of a metal by electrochemical reaction or of the tissues by the action of a strong acid or alkali; an agent that so acts. Environments), sponsored by Rapra Technology Ltd., will be held September 8-9 in Cologne, Germany. This two-day conference will focus on the use of polymers (including thermoplastics, rubbers, reinforced plastics and coatings) in aggressive and/or corrosive environments. Aggressive chemical environments are surprisingly common, and not just in the pipe or chemical industries, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Rapra. Cleaning fluids, solvents, aircraft and vehicle oils and fuels, bleach bleach Solid or liquid chemical compound used to whiten or remove the natural colour of fibres, yarns, paper, and textile fabrics. Sunlight was the chief bleaching agent up to the discovery of chlorine in 1774 by Karl Wilhelm Scheele (b. 1742—d. , oxidizing agents, acids and alkalis are said to present a corrosion threat. Even ordinary water and steam can induce damage over time. Plastics and reinforced plastics can resist some of the chemicals that are most damaging to metals, although they may themselves be susceptible to stress cracking as a result of the combination of stress and chemicals, according to Rapra. There may be a deterioration de·te·ri·o·ra·tion n. The process or condition of becoming worse. in their mechanical properties as a result of swelling by the liquid. Food packaging, landfill membranes and medical devices also need to be able to withstand the processes of permeation per·me·a·tion n. The process of spreading through or penetrating, as in the extension of a malignant neoplasm by continuous proliferation of the cells along the blood or lymph vessels. and diffusion. Polymer coatings can be used to protect metal substrates. Rubber products are sometimes deployed in corrosive situations, often requiring careful choice of the elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. . It is desirable for all these corrosion resistant materials to be able to withstand a wide range of operating temperatures, as well as corrosive chemicals, according to Rapra. This conference will present information on new materials for resisting corrosive environments, such as those encountered in sewerage sewerage, system for the removal and disposal of chiefly liquid wastes and of rainwater, which are collectively called sewage. The average person in the industrialized world produces between 60 and 140 gallons of sewage per day. and other pipe, the offshore oil industry, oil drilling and transportation, the chemical and petrochemical petrochemical, any one of a large group of chemicals derived from a component of petroleum or natural gas. The cracking processes for manufacturing gasoline produce vast quantities of gaseous hydrocarbons. industries, vehicles, aircraft, marine applications, medical devices, kitchen and food equipment, and plastics packaging. New knowledge and theories about the behavior of plastics, rubbers, reinforced plastics and polymer coatings will be presented, along with case histories. Examples of situations calling for improved anti-corrosion polymers will be presented. Fundamentals and applied research into the behavior of polymers in anti-corrosion applications will also be presented. Along with technical presentations, PACE 2004 will also feature a table top exhibition to run alongside the conference.
