Mitsui has developed a new type of yellowing resistant polyurethane elastomer

Recently, Japan's Mitsui Chemicals has developed and produced a new type of polyurethane elastomer called Fortimo, which is expected to be launched on the market in April 2015. Mitsui Chemicals' factory in Nagoya, central Japan, will produce this special polyurethane elastomer .

This is a polyurethane elastomer based on a new type of aliphatic isocyanate. Compared with traditional isocyanate-based elastomers, the new product has better elasticity, durability, and better heat resistance. Fortimo is said to be non-yellowing and has a shorter molding time than conventional elastomers. Target applications for this product include automotive, medical tubing, and highly durable industrial materials. Initially, this product will be produced at an existing Mitsui Chemicals factory, and in 2016, Mitsui Chemicals will put into use a new factory for this product in Nagoya.

Meanwhile, Mitsui Chemicals has also developed a polyisocyanate based on 1,5-cyclopentane diisocyanate (PDI). This product is more reactive than 1,6-hexamethylene diisocyanate (HDI). Its target applications include plastic coatings. PDI is based on 70% biomass and is also non-yellowing.
