High density polyethylene (HDPE) is defined by ASTM D1248-84 as a product of ethylene polymerisation with a density of 0.940 g/cm or higher. This range includes both homopolymers of ethylene and its copolymers with small amounts of a-olefins. The first commercial processes for HDPE manufacture were developed in the early 1950s and utilised a variety of transition-metal polymerisation catalysts based on molybdenum (1), chromium (2,3), and titanium (4). Commercial production of HDPE was started in 1956 in the United States by Phillips Petroleum Company and in Europe by Hoechst (5). HDPE is one of the largest volume commodity plastics produced in the world, with a worldwide capacity in 1994 of over 14 x 10 t/yr and a 32% share of the total polyethylene production. 

The process was invented and developed in Australia in the 1960s, initially by R. G. Becher at the Mineral Processing Laboratories of the West Australian Government Chemical Centre, and later by Western Titanium. In 1998 it was operating in three companies at four sites in Western Australia. Most of the beneficiate is used for the manufacture of titanium pigments some is used in titanium metal production and in welding rod coatings. Annual production in 1997 was approximately 600,000 tonnes. 

Manufacturers have already begun to take advantage of some of these nanoparticle properties. Sunscreens, which protect users from burns by absorbing or deflecting harmful rays, are often made from chemicals such as titanium dioxide or zinc oxide that are particularly effective. These sunscreens often leave a whitish residue—which used to be common on the nose of a pool or beach lifeguard—but when companies embedded nanoparticles of titanium dioxide or zinc oxide instead of bulkier particles, the creams become transparent yet maintained or even increased their effectiveness. With no embarrassing residue, these sunscreens have become popular. 

Modification of the polymer or the presence of additives can effect the light resistance of a fiber. This is extremely important for textile conservation since fibers being produced currently by the man-made fiber industry may perform differently from those produced in earlier years. For example, a company bulletin, published first in 1960, reported that the resistance to chemical decomposition by fluorescent light or by sunlight of many of the nylons they manufactured had been improved (20). Titanium dioxide, which is used as a delustrant during the manufacture of fibers, can decrease their light resistance (13,15,18, 21, 22, 23). Dyes (18, 24, 25) and finishes (25, 26) are other important factors. 

The predominant product in each case was titanium trichloride (aka "tickle 3"), an active catalyst for olefin polymerization. The preferred cocatalyst was diethyl-aluminum chloride (DEAC). TiCl from eq 3.1 contains co-crystallized aluminum trichloride. TiCl from eq 3.3 may contain small amounts of complexed aluminum alkyl. Products from eq 3.1 and 3.2 were supplied commercially by companies such as Stauffer Chemical and Dart (both now defunct). Catalyst from eq 3.3 was manufactured on site by polyolefin producers, usually in an inert hydrocarbon such as hexane. 

The technical importance of glass ceramics, produced under different trade names by various glass companies, was already mentioned in 2.9. With the code number 7971 Corning [61] developed an ultra low expansion titanium silicate glass, manufactured by flame hydrolysis. This glass, called ULE, is formed as large boules, typically 1.5 m in diameter by 0.15 m in thickness, from which virtually any size product can be fabricated using a variety of techniques. Both materials have a thermal expansion of even less than 0.2.1 O 7 K, 1 and are transparent between 0.5 and 2.3pm. 

Laporte. This company started by producing hydrogen peroxide in Yorkshire in 1888 for the textile industry. Hydrogen peroxide, other peroxides, and perborates continue to be a major interest today. They also produce a variety of predominantly inorganic chemicals, e.g. titanium dioxide, fuller s earth. Major manufacturing plant is located at Widnes near Liverpool.
