PCTFE - Polychloro-trifluoroethylene
Polychloro trifluoroethylene (abbreviated PCTFE) A crystalline polymer that is known primarily for its barrier properties. PCTFE films are optically clear, bondable to other carrier materials such as PVC and PET. It is primarily used in blister packaging for pharmaceuticals due to its excellent resistance to moisture. When thermoformed, PCTFE exhibits excellent detail and clarity. Common tradenames for PCTFE are Aclar, Kel F
Benefits & Liabilities of PCTFE
Benefits:

- Non-Flammable
- FDA compliant
- Good electrical insulating properties
- Optically clear
Liabilities:
- High Cost
- Max use temp is lower than other fluoropolymers (150 C)
- Not compatible with chlorinated solvents
