Which quality indicators matter besides epichlorohydrin content?

Water, color, acidity and process-specific impurities can affect reaction consistency and the quality of resins or other products made from ECH. Compare the limits and test methods as well as ECH content; a single purity percentage does not describe the full grade.

Epichlorohydrin (ECH) CAS 106-89-8

Epichlorohydrin (ECH, CAS 106-89-8, EC 203-439-8) is a reactive chlorinated epoxide used as an industrial intermediate for epoxy resins, elastomers and ion-exchange resins. Epoxy Resin is a downstream product family made using ECH chemistry; resin type and grade determine its application. ECH content, water, color, acidity and relevant impurities define the supply specification. Packaging and transport conditions are stated in our quotation for the quantity and destination. For a quotation, send the required specification, quantity and destination.

Product Overview

Epichlorohydrin is a raw material for epoxy resins and epichlorohydrin elastomers. Polyamide Epichlorohydrin (PAE) is a downstream paper wet-strength resin, while Ethylenediamine (EDA) is a complementary reactant in certain ECH-based ion-exchange-resin processes. These are manufacturing relationships, not direct product substitutions. ECH is flammable, acutely toxic, corrosive and a skin sensitizer; handling and storage must follow the SDS for the supplied grade.

Storage, Safety and Documentation

We can provide COA (Certificate of Analysis), TDS (Technical Data Sheet), SDS (Safety Data Sheet) and applicable GC quality data for Epichlorohydrin. Compare ECH assay results only when the test method and reporting basis are stated; GC area percentage is not automatically a mass percentage. Water is measured separately, commonly by Karl Fischer, and color can be reported on the APHA/Pt-Co scale. Use the handling and storage requirements in the SDS we provide for the supplied grade.

FAQ - Technical & Supply Chain

Q:
Is Epichlorohydrin the same material as chloromethyloxirane?

A: Yes. Chloromethyloxirane is a chemical name for Epichlorohydrin, CAS 106-89-8. It is a reactive chlorinated epoxide used as an industrial intermediate; it should not be confused with an epoxy resin or with a finished epoxy formulation.
Q:
Which quality indicators matter besides epichlorohydrin content?

A: Water, color, acidity and process-specific impurities can affect reaction consistency and the quality of resins or other products made from ECH. Compare the limits and test methods as well as ECH content; a single purity percentage does not describe the full grade.
