From selection to supply
A grade name alone does not define every property of a supplied material. Request the relevant technical information, evaluate a representative sample in your own compound and agree the specification before ordering.
This page provides general grade-reference information. It does not confirm current production, stock, numerical performance values or suitability for a particular formulation. Ask Sanjiong to confirm the supply proposal for your requirements.
