MAT-PTFE

PTFE

Gaskets, seats, seals, diaphragms, chemically resistant wetted parts, and low-friction product-contact components.

FluoropolymerSuitableStrong

Material Identity

Material FamilyFluoropolymer

AliasesPolytetrafluoroethylene, Teflon

Product ContactSuitable

Wetted UseStrong

Typical Limits

Temperature-200C to 260C typical grade range

Pressure / VacuumExcellent vacuum service; pressure rating depends on gasket profile, fitting standard, compression, and supplier grade.

Solvent ServiceBroad solvent resistance including common hydrocarbon and alcohol service; confirm grade for extreme oxidizers.

GMP / PharmaCommonly used in GMP product-contact applications where supplier grade, surface finish, and documentation are controlled.

Engineering Evaluation

PTFE

Overall ResultPASSPass

PTFE is available as a shared Material of Construction reference for Engineering Components.

Materials LibraryFluoropolymer Component Usage6 components Applicable Guidance9 rules

Supporting Findings

MaterialsPass

PTFE is captured as a shared Material of Construction record.

Materials Library records are shared engineering definitions consumed by Engineering Components rather than duplicated free-text material fields.

Product ContactPass

Product-contact suitability: Suitable; wetted-use suitability: Strong.

Depot distinguishes Material of Construction, product-contact suitability, and wetted-use suitability so engineering evaluation can reason about service exposure.

Engineering Basis: Wetted product-contact components use approved Materials of Construction

Engineering ComponentsPass

6 Engineering Component specifications reference this material.

Component usage shows where the shared material definition is consumed by the engineering baseline.

MaterialsPass

Product Contact: Suitable.

Commonly used for hygienic product-contact seals and gaskets.

This is an advisory engineering evaluation. Depot does not block procurement, create approvals, create QA work, create maintenance work, change inventory, or create validation, qualification, calibration, or change-control workflows from this panel.

Engineering Rules Referencing This Material

Product-contact solvent-wetted gaskets should use PTFE or an approved FKM compound with supplier-grade documentation.Product-contact solvent gaskets use PTFE or approved FKM

MaterialsCriticalRule

Silicone is not generally preferred for routine heptane-wetted service; use PTFE or approved FKM unless engineering review says otherwise.Hydrocarbon solvent service avoids silicone gaskets

Process MediaReview RequiredRule

Vacuum-service equipment should use vacuum-rated gauges, assemblies, seals, and sight glasses for the defined design vacuum.Vacuum service uses vacuum-rated gauges
