Manufacturer Comparison

How to Choose a Reliable Manufacturer

When comparing manufacturers, buyers should focus on practical product and supply factors.

Product Specification

Important parameters may include:

• Appearance

• Water content

A recent batch COA is particularly useful for confirming the actual quality of the supplied material.

Packaging and Supply Capability

Buyers should also confirm:

• Minimum order quantity

• Sample availability

• Drum or IBC packaging

• Lead time

• Supply capacity

• Export experience

For a new supplier, sample testing in the actual polyurethane formulation is recommended before moving to large commercial orders.
