OPCM / IPCM

Organic and inorganic foundation PCM grades for broad thermal-storage applications.

• High storage density — typical latent heat ≥ 200 J/g
• Low supercooling — ≤ 5°C
• Cycle stability — ≥ 5,000 cycles
• Phase-change temperature adjustable (e.g. 15–40°C grades; latent heat 150–320 kJ/kg in verified ranges)

Example organic grades from the product handbook: OPCM0 / OPCM21 / OPCM28 / OPCM35 / OPCM44 with melting points from 0°C to 44°C and latent heat typically ≥175–240 J/g. Inorganic examples include IPCM50 (50°C, ≥220 J/g) and IPCM58 (58°C, ≥230 J/g).

MPCM

Microencapsulated phase-change materials with a stable shell–core structure.

• Stable capsule wall — low leakage risk
• Dispersible in water, oil, and polymer systems
• Suitable for textiles, coatings, and complex operating conditions

Example grade (MPCM44): phase-change temperature 44 ± 2°C (ASTM D3418), enthalpy 210 ± 10 J/g, solids 99 ± 1%, particle size D90 = 19–24 μm. Coupled with TEC + PCM in 1.5C discharge tests, peak temperature can drop from ~88.7°C to ~42–43°C with ΔT < 5°C.

PCE

Fluid-type phase-change emulsions that deliver latent-heat cooling in pumpable form.

Validation example: 40% paraffin PCE microchannel liquid cooling under 2.0C discharge — battery peak temperature ≤ 40°C, module ΔT ≤ 5K, pumping power ~36% lower than water cooling.

Typical PCE28-40%: melting peak ~28°C (27–29°C), freezing peak ~27°C (26–28°C), storage capacity on the order of 110 kJ/kg (±7.5%), supporting precise temperature plateaus for battery and module cooling.

HPCM

High-thermal-conductivity composite PCM that remains solid during phase change while providing strong heat storage and conduction.

• Thermal conductivity about 1.5–20 W/(m·K) (≥10× traditional PCM in selected grades)
• Form-stable, leak-resistant composite structure
• Supports electric heating — cooling + heating integration
• Operating window roughly −20°C to 100°C (tunable); latent heat 150–250 kJ/kg; cycle life ≥ 5,000

Ideal for electronics cooling, battery thermal balancing, and industrial waste-heat recovery under high heat flux.
