Heptadecane is a straight-chain alkane hydrocarbon utilized primarily as a phase change material (PCM) and an industrial chemical intermediate. It serves as a reliable thermal energy storage medium in temperature-regulated applications and functions as a specialized solvent or reference material in chemical processing. We supply industrial-grade Heptadecane with standard technical documentation, including Certificate of Analysis (COA), Technical Data Sheet (TDS), and Safety Data Sheet (SDS).

FAQ
What regulatory and technical documents accompany each shipment?
Every batch is supplied with a comprehensive Certificate of Analysis (COA) verifying purity parameters, alongside updated Technical Data Sheets (TDS) and Safety Data Sheets (SDS).
Can Heptadecane be directly incorporated into polymer matrices for PCM applications?
Yes, Heptadecane is commonly microencapsulated or blended into polymer matrices, composite boards, and textiles to provide latent heat storage capabilities near its melting point.
Is this product suitable for high-temperature thermal storage systems?
No, Heptadecane is specific to low-temperature or ambient temperature regulation due to its phase transition phase point of approximately 21°C to 23°C.
