Organic Synthesis Technology

Many auto parts are made using EPDM, a synthetic rubber with excellent heat resistance and weatherability. To produce EPDM, ENB (5-ethylidene-2-norbornene) is typically used as a third monomer. Between operations in the USA and Japan, we can produce some 62,000 tons of ENB per year using proprietary technology, which is more than any other producer worldwide. Our work with ENB production technology has given us valuable know-how and reaction control technology for olefin production. We've been building on this technology to develop a variety of new monomers in recent years.
Examples include EPOCHALIC™ THI-DE, a new low-viscosity alicyclic epoxy compound, and ENEHYDE® CpODA, a new dianhydride that can be used with a polyimide to produce transparent films with high heat resistance. We're working on new products that make the most of the properties that alicyclic compounds have to offer, such as transparency, high reactivity, and high heat resistance.

High Heat-Resistant Resin Compounding Technology

We developed a new high heat-resistant thermosetting resin by combining alicyclic epoxide created using our own organic synthesis technology with our resin compounding technology. Our thermosetting resin shows much higher heat resistance (high glass transition temperature over 250°C) than resins that rely on conventional curing systems (phenolic, cationic). And because it also has low viscosity, it can be compounded with large amounts of fillers, and shows a low linear expansion coefficient over a broad range of temperatures. We think these useful features would make the resin an excellent choice for an encapsulant for semiconductors and an array of other applications.
