Frequently Asked Question
What is PCM IN33 and what applications is it best suited for ?
PCM IN33 is an inorganic phase change material designed for ultra-low temperature applications. It is particularly well-suited for use in areas requiring ultra-low temperatures, such as the transportation of pharmaceuticals, vaccines, biomedical products, and frozen foods. This material offers a reliable alternative to dry ice, maintaining consistent temperature ranges for extended periods, even under challenging external conditions. Its stable thermal properties make it an efficient solution for cold chain logistics and temperature-sensitive shipments.
What packaging options are available for IN33?
IN33 is available in various formats, including pouches, bottles, and foam-embedded units, allowing flexibility in designing shipping containers or cold storage systems.
How long can IN33 maintain frozen or near-frozen temperature during transit or storage?
The actual hold-over time depends on factors such as ambient temperature, insulation quality, packaging design, and thermal load (mass of goods). You should test in your specific setup to get realistic estimates.
Is IN33 reusable or rechargeable?
Yes — IN33 is designed for repeated thermal cycling. The lifespan (number of cycles before noticeable degradation) depends on handling, exposure to extremes, and how much mechanical stress it sees.
Can I request sample units of IN33 for evaluation?
Yes — there is a “Request Sample” option on the product page for customers to test IN33 under their own conditions before ordering at scale.
