Maleic Anhydride

Maleic anhydride is produced by oxidation of benzene or a C4 hydrocarbon such as butane in the presence of a vanadium oxide catalyst. Maleic anhydride can be converted to maleic acid by hydrolysis and to esters by alcoholysis.

14BG

14BG (1,4-Butanediol) is a straight chain glycol with hydroxyl groups on both ends. It is used as a raw material for high performance polyester and polyurethane resins as well as for industrial chemicals like tetrahydrofuran and gamma-butyrolactone. Since 1982, Mitsubishi Chemical's Yokkaichi plant has produced high-purity, high-quality 14BG from butadiene using our proprietary technology.

Si Etchant Series is a silicon wafer etching acid for spin etching processer that eliminates damaged process layers from wafer surfaces.

Mitsubishi Chemical Research Corporation is a comprehensive think tank focused on the field of science that undertakes probing and extensive data mining, information processing and research and analysis centered on the chemical, biotechnology, nanotechnology, environmental and energy sectors. We contribute to the realization of a knowledge creation society through furnishing scientific and technical information, market data and management intelligence, as well as detailed practical proposals that answer the needs of our clients.

Synthetic paper, from its early development and historical evolution, has typically been manufactured using synthetic resin derived from petroleum as its primary material. Naturally, this has given it characteristics similar to those of plastic film, but its appearance is remarkably similar to that of regular paper made from wood pulp. In addition, many synthetic papers have properties similar to those of regular paper.

YUPO® is a synthetic paper made mostly from polypropylene film to which inorganic fillers and small amounts of additives are added. In principle, the film is formed while creating microvoids by stretching it biaxially. The most distinguishing feature is its multilayer construction, which consists of a base layer and paper-like layers laminated on either side, whose thickness can be adjusted to provide products ranging from thin to thick. This manufacturing process is shown in the flow sheet in Figure 1. The specific YUPO® manufacturing process is a proprietary technology unique to our company, and numerous patents have been established for it in Japan, Europe and the USA, as well as for the composition.

The core of our technology is centered on analysis and evaluation of a wide range of polymer materials, from general-purpose resins to engineering plastics. We, as professional analytics specialists, support sincerely customers by performing various types of polymer analysis based on wealth of experience (separation analysis using various forms of chromatography,  analytics using spectroscopic analysis, etc.) to help with material development and the resolution of problems on manufacturing process.
