- Dryer fabric for papermaking
The PPS monofilament has impressive mechanical strength, resistance to corrosion, heat and flame, as well as dimensional stability. These characteristics make it a great choice for filtering and conveying special hot materials, like a dryer screen in the paper industry. Current papermaking press felts utilize PET monofilament and are built to withstand lower temperatures. However, with modern, high-speed papermaking machines, there’s a need for heat resistance materials. The PPS monofilament dryer fabric offers better protection against heat, aging, acid, alkali, and hydrolysis, increasing the product's service life significantly in comparison to traditional PET-based alternatives.
- Base material anticorrosion
PPS powder coating is beneficial for industrial anticorrosion due to its superior bonding capabilities to metal surfaces compared to traditional PTFE linings. Unlike PTFE, the PPS coating does not come off easily.
- Compound extrusion
PPS and PTFE fine powders are blended and compounded, resulting in the production of a line pipe sleeve via extrusion sintering. Alternatively, this mixture can be mould pressed and sintered to create a self-lubricating composite material. Compounding offers improved resistance to wear and creep, while still preserving the material's temperature and chemical corrosion resistance.
- Emulsion coating
To improve the adherence of the non-stick coating, a mixture of PPS and fluorine-containing materials is needed. This is due to the low bonding force between the PTFE surface layer and the aluminum or steel underlying layer.
