PCM based heat sink film

Key specifications:
• Phase-change range:40 ~ 45 ℃
• Heat capacity:140 kJ/kg
• Thickness: 0.2 mm
• Flame retardant grade: V0


PCM based heat sink colloid

Key specifications:
• Phase-change range:37 ~ 40 ℃
• Heat capacity:140 kJ/kg
• Thermal conductivity:1,5 W/(m K)
• Flame retardant grade: V0
• Stability: no fluidity happens even if the colloid melts under 50~60 ℃
