"Polyisocyanate" Meaning
A polyisocyanate is a type of organic compound that contains isocyanate groups (-NCO) attached to a polymer chain. These compounds are used as diisocyanates or multimeric isocyanates with isocyanate groups at both termini of the molecule. Polyisocyanates contain as their main component an organic polymer which consists of isocyanatoalkylene structures, often obtained by self polymerization of diisocyanates, and organic segments, generally of low molecular weight.

Polyisocyanurate
A type of polyurethane foam insulation.Definition: Polyisocyanurate (PIR) foam is a type of rigid foam insulation that is made from polymeric isocyanates and a foaming agent. It is a type of thermoset foam, meaning that it is created through a chemical reaction and cannot be melted or reshaped once it is formed.Properties: PIR foam is known for its:1. High R-value (thermal resistance): 6.5-8.0 per inch (26-32.7 per cm), which is higher than other types of foam insulation.2. Low moisture absorption: PIR foam has a low moisture absorption rate, making it a good choice for areas with high humidity.3. High fire resistance: PIR foam is non-combustible and meets the requirements for Class 1 fire rating.4. Durability: PIR foam is resistant to wear and tear, and can withstand exposure to weathering and UV radiation.Applications: PIR foam is commonly used in building construction as insulation in:1. Walls and floors2. Roofs and ceilings3. Attics and crawl spaces4. Pipework and ductworkIt is also used in refrigeration and cold storage applications, and in the manufacture of various products, such as building panels, door and window insulation, and packaging materials.
