Feuille moulée en PTFE
- Excellent chemical resistance– you can make liners and seals for chemical tanks, gasket tapes, sealing applications, etc.
- Low friction co-efficient– hence suitable for sliding bearings, non-stick liners
- Superior dielectric properties– due to the non-polar structure hence a perfect choice for electrical insulation. It conforms to the ASTM D149 requirements.
- High heat resistance and excellent temperature performance– you can use it to make PTFE seals and gaskets
- Non-toxic– thus approved by FDA for making food processing products such as non-stick cookware
Description about PTFE Molded Sheet From Hansa
Generally, processing PTFE molded sheets requires special attention before other processes such as injection molding. For instance, most manufacturers have adopted:
- First, compression molding PTFE powder
- Second, get the preform, then subjected it to a sintering process before molding Polytetrafluoroethyleneinto sheets.
PTFE Molded Sheet Options
Molded PTFE sheets are available in many options according to custom options:
Standard to Cut to Size Dimensions and Thickness
Although the PTFE molded sheet manufacturer may have specific dimensions according to their tooling design, they can cut the sheets to any size.
Virgin Grade Molded PTFE Sheets
The PTFE sheets are made from 100% pure Polytetrafluoroethylene material.
Modified PTFE Molded Sheets
Depending on specific applications requirements, molded PTFE sheets may have other additives such as:
- Glass-filled PTFE Sheet
- Carbon-filled PTFE Sheet
- Graphite-filled PTFE Sheet
- Bronzed-filled PTFE Sheet
- Molybdenum disulfide-filled PTFE sheet
Usually, the percentage of the added additive or filler may range from 15% to 45%, depending on the desired properties of the PTFE molded sheets.
Remember, there are many filler options.
We have 100% virgin PTFE molded sheets,and filled PTFE sheets,including glass fiber filled PTFE,carbon filled PTFE bronze filled PTFE, the most popular size 1000*1000mm,1200*1200mm,1500*1500mm,thickness can be from 3mm to 120mm.
Our ptfe molded sheet is completely sintered,without any black color inside, they can be used to process various parts.
We have more than 60 tons of ptfe moled sheets stocks in our warehouse,produce all ptfe sheets,rods tubes,almost 280tons per month.
Coefficient of friction (COF) as low as 0.04, featuring a smooth surface with self-lubricating properties that eliminate the need for external lubricants.
Demonstrates favorable compressive and creep resistance at ambient temperatures, though may soften under elevated temperatures, suitable for low-stress applications.
Exhibits corrosion resistance capable of withstanding aggressive agents and the majority of chemical media (pH 0-14).
Operational range spans from -200°C to +260°C for sustained service, with short-term exposure tolerance up to 300°C.
Application Of PTFE Skived Sheet
Industrial: Seals, gaskets, bearings, valve components, and linings for pipes and tanks.；
Electronics: Insulation for circuit boards, connectors, and electronic components；
Automobile: Bushings, hoses, and coatings for fuel lines；
Food & Beverage: Conveyor belts, molds, and containers；
Medical: Catheters, implantable devices, and labware.
Production Process for PTFE sheets As Following Steps
Raw Material Specifications for PTFE Sheets；Primary resins sourced from Shandong Dongyue (China) and Daikin Industries (Japan), predominantly suspension-polymerized medium-grade formulations, compliant with FDA and REACH regulatory requirements.
Raw material processing: crush it through 10-20 mesh sieve, and place it in 23℃-25℃ environment for temperature adjustment for 24h-48h. Molding: pressure 17.5-35MPa, pressure holding time 1-10min.
Sintering: sintering temperature 360℃-380℃, heating rate 30℃/h, 330℃ for 2h,370℃ for 3h. Cooling: cooling rate 20℃/h, slowly around 330℃ near the melting point of PTFE
