Products Description

product feature

POM (polyformaldehyde) and PTFE (polytetrafluoroethylene) composite materials combine the chemical properties of the two, and are often used in industry for corrosion resistance, low friction and other scenarios. The following is an analysis of its key chemical properties:

1. Acid and alkaline resistance
PTFE strong tolerance: PTFE is inert to almost all strong acids (concentrated sulfuric acid, hydrochloric acid, nitric acid), strong bases (sodium hydroxide, potassium hydroxide) and strong oxidants (such as aqua regosa), and has very high chemical stability.
Limitations of POM: Pure POM is easy to decompose in strong acids (such as concentrated sulfuric acid) and strong bases (such as sodium hydroxide solution), but after being combined with PTFE, its acid and alkali corrosion resistance is significantly improved, especially in medium concentration acid and alkali environments.
Synergistic effect: PTFE as a dispersed phase can form a barrier, reduce the direct contact between the POM matrix and the corrosive medium, and delay degradation.
2. Solvent resistance and swelling
PTFE swelling resistance: PTFE is almost insoluble in any organic solvent (such as , benzene, alcohol), and the swelling rate is very low.
POM sensitivity: POM is easily eroded by polar solvents (such as phenols, chlorinated hydrocarbons), but after being combined with PTFE, the solvent penetration path is blocked, and the swelling rate is reduced by more than 50%.
Application scenario: Applicable to components that need to contact fuel oil, lubricating oil, or weakly polar solvents (such as automotive fuel system seals).
3. High temperature resistance and thermal stability
PTFE high temperature resistance: PTFE long-term use temperature can reach 260 ° C, short-term temperature resistance of 300 ° C, and still remain chemically inert at high temperatures.
