films

Confirm the resin or compound, manufacturing route, dimensional tolerance, inspection method and batch traceability. The drawing and service conditions should be reviewed before price becomes the deciding factor.

Send the required grade, dimensions, tolerance, quantity, operating temperature, chemical media, mechanical load, documentation and delivery destination. Photos or drawings help prevent quotation assumptions.

Custom dimensions and secondary processing can be reviewed from a drawing, sample or application specification. Feasibility depends on the material, production method, tolerance and order volume.

Film usually refers to thinner flexible material supplied in rolls or cut sheets. The dividing thickness varies by supplier, so specify thickness, tolerance, width, roll length and surface treatment.

Compare PTFE, ePTFE, FEP, PFA, PEEK and PI films by thickness, dielectric performance, temperature, transparency, pore structure, surface treatment, roll width and converting requirements.

Provide nominal thickness, tolerance, roll width, roll length, core size and winding requirement. Slitting yield and edge quality should be agreed for narrow rolls.

Untreated fluoropolymer surfaces are difficult to bond. State the adhesive, lamination process and treated side so surface treatment and handling can be reviewed.

Samples and prototypes can be reviewed before a production order. Approval criteria should identify critical dimensions, appearance, material grade and any required test records.

Review the Fluoroplastics material guide and the film product range before choosing an alternative.

Define the test method, thickness, frequency or pressure differential and acceptance value. Generic material data should not replace a test requirement for the supplied film.
