Detailed description of f4 sheet
Chemical name: Polytetrafluoroethylene
Morphological structure: A white, odorless, and non-toxic crystalline polymer material made from pure PTFE resin through molding, sintering, and mechanical processing. Its molecular structure consists of linear carbon chains completely enveloped by fluorine atoms (C ₂ F ₄) ₙ.
Board type:
Pure PTFE board: a base board that has not been filled or modified.
Filling modified PTFE plate: adding glass fiber, graphite, carbon fiber, bronze powder, etc. (filling rate of 5%~40%) to enhance mechanical or thermal conductivity.
Expanded PTFE sheet (ePTFE): formed into a microporous structure through stretching process, possessing both flexibility and breathability.
Product performance of ptfe plastic
Physical property
Density: 2.1~2.3 g/cm ³ (pure PTFE); The filling type is slightly higher (such as about 2.4 g/cm ³ filled with 25% glass fiber).
Hardness: Shore D 50~65 (ASTM D2240).
Color: white/gray (filling type may app…
