What is the difference between Polyol and MDI in a PUF chemical system?

Polyol and MDI are the two reactive components of a rigid polyurethane foam system. When mixed in the correct ratio, they react to form the rigid, closed-cell foam structure. They must be sourced as a matched, compatible system rather than combined arbitrarily from different suppliers.

How much does rigid PUF chemical cost per kg in India?

Rigid PUF chemical (Polyol + MDI systems) typically ranges from Rs 175 to Rs 350 per kg in the Indian market, depending on formulation performance, pack size, included technical support, and whether the supplier is a manufacturer or a reseller.

What is rigid PUF chemical used for?

Rigid PUF chemical is used for thermal insulation and structural rigidity in refrigerators, freezers, deep freezers, cold storage rooms, insulated sandwich panels, refrigerated trucks and reefer containers, insulated doors, and other temperature-controlled applications.

Is a sample or trial pack available before buying in bulk?

Reputable suppliers should offer a smaller trial quantity so buyers can validate reactivity, density, and finish quality on their own equipment before committing to a bulk order. This is one of the most important checks to make before choosing a supplier.

What GST rate applies to PUF chemical purchases?

Rigid PUF chemical components generally fall under HSN classifications within Chapter 39 (polyurethanes and related resin products) and typically attract 18% GST. A properly registered supplier will issue a compliant GST invoice enabling input tax credit.
