Frequently Asked Questions

PTFE offers unmatched performance benefits such as:

• Resistance to chemicals, acids, and solvents
• Excellent thermal stability (–200°C to +260°C)
• Low coefficient of friction and self-lubrication
• Non-stick, anti-corrosive, and weather-resistant
• Electrical insulation and dielectric properties

These properties make it ideal for chemical processing, pharmaceuticals, automotive, electronics, aerospace, and food-grade applications.

Our PTFE solutions are trusted across:

• Chemical & petrochemical plants
• Pharmaceutical & biotech equipment
• Automotive, railways & aerospace
• Electrical & electronics manufacturing
• Food processing machinery
• Oil & gas sector
• Water treatment & infrastructure
• Heavy industrial and mechanical equipment

Molded PTFE sheets are pressed under heat and pressure and are ideal for thick, rigid sheet requirements with excellent dimensional stability.
Skived PTFE sheets are shaved from a PTFE billet and are perfect for thinner, flexible applications such as electrical insulation, seals, or non-stick linings.
We offer both types in various thicknesses and custom sizes.

Yes. National Fluoromers offers chemically etched PTFE sheets, also known as PTFE bonding sheets, with one or both sides etched for adhesive bonding to metals, rubbers, or composite materials. These are commonly used in linings, diaphragms, expansion joints, and industrial anti-corrosion applications.

Filled grades of PTFE are designed to improve the mechanical, thermal, or electrical performance of virgin PTFE. Popular filled grades include:

• Glass filled PTFE – for higher dimensional stability and wear resistance
• Carbon filled PTFE – for increased compressive strength and conductivity
• Bronze filled PTFE – for better heat dissipation and rigidity
• Graphite filled PTFE – for low-friction, dry-running components
• Glass + MoS₂ or Bronze + MoS₂ PTFE – for high-load and low-friction balance

Yes. We specialize in precision-cut and custom-fabricated PTFE gaskets, o-rings, seal rings, envelope gaskets, and valve seats that are used in chemical pipelines, pressure vessels, pumps, and rotating equipment. These are also available in virgin or filled PTFE materials.

Absolutely. We manufacture customized PTFE components as per drawings or samples, including:

• PTFE washers, guide rings, stem washers
• PTFE d-seals, rod seals, and lab scoops
• PTFE bellows (single/composite type)
• Turcite® PTFE wear/slide lining sheets
• CNC-machined PTFE blocks, discs, balls, and rings

We serve OEMs, machinery manufacturers, and R&D labs worldwide.

PTFE bellows are flexible connectors designed to compensate for vibration, thermal expansion, and misalignment in piping systems. These are commonly used in:

• Chemical transfer lines
• Acidic and caustic fluid handling
• Pump and compressor piping

We offer both standard and composite PTFE bellows in various sizes.

Our range includes:

• Molded PTFE rods (for structural and load-bearing applications)
• Extruded PTFE rods (for lightweight, machinable parts)
• PTFE bushes & cylinders in virgin and filled grades
• PTFE envelope bushes for corrosion-resistant bearings

Yes. Many of our virgin PTFE products conform to FDA, EU, and food-contact standards, making them suitable for use in:

• Food processing
• Beverage bottling
• Dairy equipment
• Pharmaceutical manufacturing

Yes, we export to clients across the globe. All our products are manufactured under strict quality control, packed as per international shipment standards, and can be supplied with batch traceability, inspection reports, and material test certificates (MTCs).
