Hydroxyethylmethacrylate or HEMA is the organic compound with the formula H2C=C(CH3)CO2CH2CH2OH. It is a colorless viscous liquid that readily polymerizes. HEMA is a monomer that is used to make various polymers.

Polyhydroxyethylmethacrylate is hydrophobic; however, when the polymer is subjected to water it will swell due to the molecule's hydrophilic pendant group. Depending on the physical and chemical structure of the polymer, it is capable of absorbing from 10 to 600% water relative to the dry weight. Because of this property, it was one of the first materials to be successfully used in the manufacture of soft contact lenses.
Mitsubishi Gas Chemicals is set to establish a cutting-edge, high-performance resin manufacturing facility in Poland, focusing on producing materials used in automotive and digital appliance components. The plant is expected to begin operations in 2010, with an estimated maximum investment of 15 billion yen. This marks the company's first foray into resin production in Eastern Europe, signaling a strategic move into emerging markets. As Japanese automakers and motor manufacturers continue to expand their presence in Eastern Europe and Russia, Mitsubishi is now stepping up its involvement in the raw material supply chain.
The project will center around the production of polyoxymethylene (POM), a high-performance resin known for its excellent wear resistance. POM is increasingly being used as a metal alternative in critical parts such as gears, switches, and drive mechanisms in both automotive and home electronics applications. This material offers superior durability and precision, making it ideal for high-demand industries.
In 2008, Mitsubishi Gas Chemicals plans to form a joint venture with a local Polish chemical company. The partnership aims to produce 40,000 tons of polyformaldehyde annually starting in 2010. The company is currently reallocating over 50% of its capital to support this new initiative, reflecting a long-term commitment to growth in the region. Under the joint venture structure, Mitsubishi will receive supplies proportional to its investment, ensuring a stable and efficient supply chain. This expansion not only strengthens Mitsubishi’s global footprint but also supports the increasing demand for advanced materials in the rapidly evolving industrial landscape of Eastern Europe.
