Polyphenylene sulphide (PPS) Plastic that combines strength with light weight. Kureha’s PPS resin has exceptional toughness and can offer significant weight reductions while resisting extreme temperatures. Due to its properties, PPS is being used as an important alternative to metal for automotive lightweighting. Kureha has recently invested ¥10bn into a 5,000 tpa capacity enhancement for PPS at its Iwaki Plant (currently 10,700 tpa). This is scheduled to be completed by February 2021.

Polyglycolic acid (PGA) A new age material to lessen environmental loads

Polyvinylidene fluoride (PVDF) Reliable and proven performance in challenging environments. Kureha was the first to produce Polyvinylidene fluoride on an industrial scale in 1970. This engineering thermoplastic serves as a binder material for electrodes in lithium-ion batteries used in a range of applications such as electric vehicles and solar panels. To meet the growing global demands for sustainable energy sources, has recently invested ¥4.7bn into a new 2000 tpa PVDF line at its Iwaki plant increasing PVDF production capacity to 11,000 tpa in 2019.

We constantly evolve through innovation. We contribute to society by developing beneficial products. Krehalon is a wholly owned subsidiary of Kureha Corporation – a Japanese specialty chemicals and plastics manufacturer listed on the Tokyo stock exchange with annual revenues exceeding $1.2 billion .

Kureha is the first and, currently, the only company in the world to successfully develop an industrial manufacturing process for Polyglycolic acid (PGA) - a biodegradable polyester resin with high mechanical strength and high gas barrier. This material, branded Kuredux®, has become a key growth driver for Kureha due to its invaluable use in the production of biodegradable frac plugs for oil and gas exploration.
