Lámina moldeada de 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 Politetrafluoroetilenointo 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 Láminas de PTFE 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.
Coeficiente de fricción (COF) tan bajo como 0,04, con una superficie lisa con propiedades autolubricantes que eliminan la necesidad de lubricantes externos.
Demuestra una resistencia favorable a la compresión y a la fluencia a temperatura ambiente, aunque puede ablandarse a temperaturas elevadas, lo que lo hace adecuado para aplicaciones de baja tensión.
Presenta resistencia a la corrosión capaz de soportar agentes agresivos y la mayoría de los medios químicos (pH 0-14).
El rango operativo abarca desde -200 °C a +260 °C para un servicio sostenido, con tolerancia a la exposición a corto plazo de hasta 300 °C.

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 y 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
