Frequently Asked Question

What is PCM OP21 and what is its application range?

OP21 is a high-temperature organic phase change material designed for temperature regulation above ambient (i.e. warmer than room temperature). It’s suitable for use in pharmaceutical shippers, medical transport, and thermal comfort jackets.

The holdover time (how long it maintains the target temperature above ambient) will depend on ambient conditions, insulation quality, heat load, and how well the PCM is preconditioned.

Yes — the product page states that OP21 is reusable. It’s designed to deliver extended temperature control under challenging conditions across cycles.

To maximize performance, combine OP21 with good insulation (e.g. foams, textile insulators, barriers) to reduce heat transfer. The insulation thickness and type should be optimized based on ambient extremes, usage duration, and thermal loads.

Yes — customers can place bulk or customized orders. Contact sales/technical support for quote, packaging customization, and design assistance.
