Available Isopentane Grades

95% Isopentane

95% Isopentane may be evaluated for selected industrial applications where this grade matches the purchaser’s agreed technical requirements. Review the grade-specific product page for further product information and documentation requirements.

99% Isopentane

99% Isopentane may be evaluated for industrial applications that require a higher Isopentane content and more defined quality controls. Review the grade-specific product page for further product information and documentation requirements.

How to Select an Isopentane Grade

The purity figure is an important starting point, but it should not be the only factor used when selecting an Isopentane grade. Industrial buyers should first identify the technical and documentation requirements of the intended application.

A practical technical review may include:

  • The intended industrial application
  • The required Isopentane grade
  • The agreed product specification
  • Relevant composition or quality items
  • Batch Certificate of Analysis requirements
  • Required product documents
  • Packaging preference and delivery destination
  • Customer-specific or destination-specific documentation requirements

Where the required grade has not yet been defined, purchasers should consult their technical team and confirm the relevant acceptance criteria before commercial ordering.

Industrial Application Areas

Depending on the selected grade and purchaser technical requirements, Isopentane may be evaluated for selected industrial applications, including:

  • Foam-related industrial applications
  • Polymerization-related industrial processes
  • Hydrocarbon blending and process applications
  • Other industrial uses subject to technical review

The purchaser should confirm application-specific acceptance criteria, documentation needs and applicable local requirements before commercial ordering.

Documentation for Technical Review

Product specifications, batch Certificates of Analysis and Safety Data Sheets may be available according to the selected grade and order requirements.

When reviewing documents, purchasers should confirm that the product name, CAS number, grade, batch information and order documentation are consistent with the agreed requirements.

For hazard classification, handling, storage and first-aid information, please refer to the Safety Data Sheet (MSDS) available on our COA and MSDS page and to the guidance of the competent authorities. Suitability for any end application should be verified by the end user and tested by qualified third-party laboratories.
