"Phase Change Like" Films(PCE Films) 86/114 & 86/117

"Phase Change Like" Films in use

Note that these new films are special elastomers and do not consist of wax material. Because of their outstanding phase changing characteristics the PCE´s or "phase change like"

Possible Thickness: 0.250mm

Advantages

  • Very good compressibility thereby very good material adaptability
  • Phase-change characteristic without containing wax material
  • No melting point but softening interval – no liquidation throughout the whole temperature range
  • Electrical insulating
  • Excellent reworkability – disassembling without damaging the components
  • Can be used for automatic production – easy automatic assembly
  • Single-sided adhesive
  • RoHS / environmently friendly
  • Also suitable for dispensing
