Collection: Phase Change Material Products

Phase Change Material (PCM) is developed to provide your shipment with the thermal protection needed to ensure safe transport. With our wide range of Phase Change Material, you will find the right PCM solution to meet your unique temperature band and shipping duration requirements. 

Phase Change Material releases thermal energy as it phases between solid and liquid. As the PCM phases (melting/freezing temperatures) it releases or stores large amounts of energy as a component of the Phase Change Material’s latent heat fusion. During this process of phasing, our PCM will maintain its specific temperature band to ensure the safe thermal climate of your payload during transit.

Our PCM, has proven to be a very effective thermal barrier/insulation between your payload and external temperature fluctuations frequently seen during transport.



(PCM) are engineered to help keep your valuable payload within the desired temperature range during transit, whether at frozen, refrigerated or controlled room temperatures. 

Saf-T-Temp Phase Change Materials are tested and pre-qualified in a variety of Saf-T-Pak insulated shipping systems, providing cost-effective solutions for many shipping requirements. Individual PCM and insulated shipping systems data sheets with thermal performance test results, preconditioning and assembly instructions are available by contacting your Territory Manager.

The Saf-T-Temp PCM line can also provide thermal protection solutions for your custom-designed packaging. We will work with your team to provide cost-effective solutions that meet your specific Phase Change Material and payload requirements. Whether you require customized systems, customized temperature PCMs or off-the-shelf, pre-qualified solutions, you can trust Saf-T-Pak to provide the correct thermal packaging solution for your requirements.
