Polyurethanes and diisocyanates are integral
compounds with diverse applications across
various industries. Polyurethanes, commonly known
as PUR or PU, are versatile polymers renowned for
their exceptional durability, flexibility, and
insulation properties. Diisocyanates serve as key
building blocks in the synthesis of
polyurethanes, contributing to their structural
integrity and performance. Together, these
compounds play a crucial role in the development
of innovative products and materials across
numerous sectors.

Manufacturing Process
The synthesis of polyurethanes involves a
versatile and adaptable manufacturing process.
Diisocyanates react with polyols in a controlled
manner to form polyurethane chains, with various
catalysts, surfactants, and additives employed to
adjust properties and enhance performance.
Methods such as batch, continuous, and reaction
injection moulding (RIM) are utilized to produce
polyurethane products with precision and
efficiency. This flexibility in production
enables the customization of polyurethanes for
specific applications, from rigid foams to
flexible elastomers.
