At a Glance
- Growing demand for high-heat resin in automotive
- Appliances, tableware, and microwavable containers among other expanding uses
- Co-location with monomer plant brings production efficiencies
Idemitsu Advanced Materials has completed construction of a second syndiotactic polystyrene (SPS) production plant in Pasir Gudang, Johor, Malaysia, and launched commercial operations in November 2023. The company is a subsidiary of Japan’s Idemitsu Kosan, which pioneered the development and commercialization of the heat-resistant styrenic engineering plastic in 1997.
9,000 tonnes/year production capacity
Production capacity of the new Malaysian plant is 9,000 tonnes per year, and with this second SPS production plant in operation, the production capability for proprietary SPS resin will be effectively doubled. The new two-location system with the first SPS production plant at the Chiba Complex in Ichihara City, Japan, has realized a more stable production and supply arrangement, according to Idemitsu.
SPS handles the heat
Xarec SPS resin is a purely Japanese engineering plastic that Idemitsu succeeded in synthesizing for the first time in the world in 1985 and achieved global-first commercialization in 1997. Its characteristics include outstanding heat resistance (melting point is 270°C), hot water resistance, electrical insulation, and radio wave permeability. SPS resin is widely used in automotive parts, including for electric vehicles (EVs); home appliances; and daily-use products such as tableware and microwave oven cooking containers. Demand reportedly is expanding steadily.
Pasir Gudang, Malaysia, where the second SPS production plant has been constructed, is one of Idemitsu’s key manufacturing sites for petrochemicals. The Southeast Asian site was selected due to demand growth prospects in the region, as well as the possibility to procure raw material styrene monomer onsite from Idemitsu SM (Malaysia) Sdn. Bhd., also a subsidiary of Idemitsu, which is located adjacent to the SPS plant.
