PCM cooling technology refers to phase change material (PCM) technology that intelligently stores and releases cold and heat energy. Lined with SGS-certified safe phase change gel, it features non-toxic, harmless, long cooling duration, non-flammable, zero-leakage, and long recyclable service life. The phase change cold storage packs are sealed with eco-friendly, skin-friendly composite materials, staying soft before and after phase transition to closely fit the skin for superior wearing comfort.
It operates in a zero-energy recycling cycle: only 1 hour is required for cold charging. Suitable for all high-temperature environments ranging from 30°C to 42°C, it delivers stable continuous cooling for 3 hours per single cold charge — far exceeding the 1-hour effective cooling time of traditional ice packs or cooling patches — and supports up to 5,000 recycling cycles.

Independently developed inorganic PCM phase-change gel technology, compounded from water-soluble polymers and inorganic cold-storage phase-change materials. It completely resolves the phase separation and leakage issues plaguing traditional inorganic phase-change materials.
This inorganic phase-change gel is non-toxic, harmless, and reusable with durable cold storage performance. It remains soft and skin-friendly throughout the phase-change process, while featuring high thermal conductivity, non-flammability, eco-friendliness, and conformable fit. It represents a groundbreaking new generation of phase-change cooling material. Delivering around 3 hours of continuous cooling relief in hot environments without any power supply, it offers healthy, soothing comfort so you can fully focus on work and your passions.
