Overview
FORTIMO™ 1,4-bis (isocyanatomethyl) cyclohexane (1,4-H6XDI) is a novel isocyanate with a highly symmetrical cycloaliphatic structure, and high performance polyurethane elastomer based on it.
As TPU (thermoplastic polyurethane) and TSU/CPU (thermoset polyurethane / casting polyurethane), it can be used for a wide range of applications including high-durability industrial materials, sporting goods, general consumer materials, automotive materials and packaging materials.
It also offers a balance between high elasticity, high heat resistance and non-yellowing properties.
*Comparison with TPUs of the same hardness (85A) based on same polyols
In addition to durability, heat insulation and non-yellowing properties, they also offer excellent molding characteristics.
FORTIMO™ TPUs offer superior elasticity and heat resistance than MDI and H12MDI type TPUs.
They also offer superior molding characteristics to MDI and H12MDI type TPUs.
The table below shows examples of physical properties when used for TPU.
