There are three main types: 1. Cast lamination.
This process is to use plastic particles to heat-melt and then rely on the viscosity of the plastic itself to compound.
The disadvantage is that it is almost airtight.
2. Spray glue or scrape glue lamination (hot melt glue lamination).
This process is to use plastic particles to heat-melt and then rely on the viscosity of the plastic itself to compound.
3. Hot pressing compound.
The ptfe waterproof and breathable membrane is prepared using unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
