STUDY GOALS AND OBJECTIVES
The objective of this study is to provide an analysis of transparent plastics in terms of current and forecasted markets. New developments in clear plastics have expanded usage in existing and new applications, and competition between polymers that exhibit optical clarity will be covered. The competitive scenario between glass and clear plastics will also be described, as well as a detailed discussion on the competition between transparent plastics. Important suppliers of clear plastics, their product lines, and other important factors that impact the market will also be covered.
REASONS FOR DOING THE STUDY
The search is continuing for special markets by most plastics suppliers, somewhat irrespective of potential volume. Selection criteria focus on growing specialty markets with opportunities for respectable profits, even though sales volumes may not be large by commodity-resin standards.
Transparent plastics is a niche market that encompasses many types of polymers. In addition to acrylics and polycarbonates, many styrene-based materials, as well as commodity and specialty polymers, have clear grades. Opportunities in several application areas need reappraising to assess their potentials for transparent or clear plastics, especially in the electronic, medical, and automotive sectors.
SCOPE AND FORMAT
The term "transparent" or "clear" is a subjective one. Most relate clarity of plastics to percent of light transmission as defined by ASTM test D-1003. Light transmission percentages above 85% usually are accepted as transparent. Other related ASTM tests are D-523 and D-542.
Clear plastics are commercially available in many forms, such as injection molded, extruded, blow molded, and thermoformed. A great number of extruded products are converted to films, and the numerous uses for these films (commodity, specialty, coextruded, plastic food, medical packaging, etc.) could be the subject of its own, separate report.
Blow-molded plastics are hollow, and most are converted to bottles or containers, while thermoformed plastics are similar to injection-molded plastics, except that they are usually thinner and require less-expensive equipment and capital outlay.
This report will cover rigid, clear, nonpackaging plastic parts, which include injection molded, nonfilm extrusion, and thermoforming (including cast sheet). The major plastic products excluded from this report will be flexible and hollow materials (including films).
A comprehensive review was undertaken of literature relating to clear polymers, their applications and technology, and significant new developments. Included in the review were supplier trade literature, texts, and monographs. Following the collection and analysis of this information, unresolved issues were discussed with producers, suppliers, and fabricators of transparent plastics.
The terms "transparent" and "clear" are used interchangeably. The acronyms PS, PP, and PC are often used to denote polystyrene, polypropylene, and polycarbonate, respectively.
Methylmethacrylate and MMA are also used interchangeably, as are polymethyl-methacrylate and PMMA. Methylmethacrylate polymers are also synonymous with PMMA.
