Microencapsulated Phase Change Material Powder (PCM, 37C) is a microencapsulated phase change material designed around a nominal phase-change temperature of 37C.

The PCM core absorbs and releases latent heat around its transition range, while the shell helps keep the material contained as a processable white to off-white microencapsulated powder. It is intended for research, prototype development, and industrial formulation trials where thermal buffering or temperature regulation is required.

Product Description:

Use this grade for functional fillers for coatings, composite materials, thermal storage panels, polymer systems, and prototype heat-buffering materials. The product should be evaluated in the actual binder, substrate, and processing temperature profile before scale-up.

Phase Change Temperature:

Nominal PCM transition temperature: 37C. Confirm actual onset, peak, and enthalpy by DSC testing for critical applications.

Usage:

Typical starting range: 1-20% depending on heat-capacity target and mechanical requirements.

Mixing Method:

Pre-disperse in the target binder or carrier, then mix into the main system with moderate shear. Avoid milling or aggressive high-shear processing after the microcapsules are added.

Product Characteristics:

Appearance: white to off-white microencapsulated powder

Composition: proprietary microencapsulated PCM system

Solubility / Dispersion:

Dispersible in water or compatible binders depending on grade and formulation. The microcapsules are not molecularly soluble; maintain uniform suspension during processing.

Storage:

Store tightly closed at room temperature in a dry, ventilated area. Avoid freezing, excessive heat, direct sunlight, and mechanical crushing.
