Hansa PTFE Molded Sheet

PTFE Molded Sheet

PTFE molded sheet is fluoropolymer made through a compression molding process. Compression molding PTFE is a critical process since it forms the foundation for making other products such as skived PTFE sheets.

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.

Known for high molecular weight due to the fluorine and carbon, PTFE molded sheet is a known engineering material with superior properties:

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

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:

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.

Molded PTFE Sheet Vs Skived PTFE Sheets

Usually, we make skived PTFE sheets from Polytetrafluoroethylene molded sheets. Comparing the two Polytetrafluoroethylene sheets, molded PTFE sheets have a larger thickness, besides having a consistently flat surface.

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.
