Fluoropolymers / Engineering plastics

PTFE (Poly Tetrafluoroethylene)

PTFE offers the best performance of all fluoropolymers. It is a thermoplastic extensively used in a wide range of industries.

PFA (Tetrafluoroethylene-Perfluoroalkoxy ethylene copolymer)

PFA has properties equivalent to those of PTFE and can be molded (by injection, etc.) in the same way as thermoplastics. NICHIAS also offers New-PFA, which has stabilized PFA-molecule terminals and low elution levels of fluoride ions, and Super-PFA (TOMBO No. 9003PFA-HG NAFLONTM PFA-HG Tubing), which has low elution levels of fluoride ions and improved surface roughness.＊ For details of TOMBO No. 9003PFA-HG NAFLONTM PFA-HG Tubing, please see the brochure for NAFLONTM Tubing.

PCTFE (PolyChloro Trifluoroethylene)

PCTFE offers high levels of mechanical strength, transparency, cryogenic properties, permeability to gases and radiation resistance.

NAFLON™ PTFE Sheet TOMBO No.9000

The NAFLON PTFE sheet is compression

molded from pure PTFE or from PTFE

mixed with a blend of powdered inorganic

fillers for a wide range of applications.

■ ApplicationWith its characteristic fluoropolymer properties such as chemical stability, excellent electrical characteris-tics and low coefficient of friction, the NAFLON PTFE sheet is widely used for gaskets, electrical insu-lating materials, mechanical parts and more. Filled-sheet versions are recommended for a working envi-ronment that demands excellent wear resistance and compressive strength.

■ NAFLON™ PTFE sheet with fillers

This is the version of the NAFLON PTFE sheet con-taining inorganic fillers to improve wear resistance, creep resistance, heat conductivity and thermal dimensional stability.These filled sheets are ideal for mechanical parts that require resistance to heat and wear.＊ Some versions of the sheet cannot be used in specific condi-tions (e.g. the type of chemical used). Please contact us for details.

NAFLON™ PTFE Tape TOMBO No.9001

The NAFLON PTFE tape is made by cut-

ting a molded cylindrical PTFE block into

a thin tape of the required thickness. It

offers a combination of PTFE’s excellent

characteristics including electrical prop-

erties, non-adherent property and low

coefficient of friction.

■ ApplicationThe NAFLON PTFE tape has a wide range of appli-cations, e.g. as insulating material for motors and gen-erators that are used in high-temperature corrosive gases, insulating material for coils, slot insulation, release material in plastic moldings and the lining of hoppers.

NOTE 1: “MD” stands for “in the direction parallel with the molding direction.” “CD” stands for “in the direction perpendicular to the molding direction.” NOTE 2: The values for SC and LC have been measured on sheets (3 mm in thickness).＊ JIS: Japanese Industrial Standards.＊ ASTM: Formerly known as the American Society for Testing and Materials.＊ Some data in this properties table are based on data provided by the fluoropolymer manufacturers. The values in this table have been obtained in experiments conducted under specific conditions (they are not standard values) and so may vary slightly depending on the actual conditions in which the fluoropolymers are used.

Prohibitions

1. Never use NICHIAS fluoropolymer products for any applications in which they can

come into contact with biomedical tissue, body fluid or other similar substances.

2. Never allow NICHIAS fluoropolymer products to enter the human body (such as by

swallowing them inadvertently).

Precautions

The following precautions must be strictly observed to ensure

correct functioning and safe use of NICHIAS fluoropolymer products.

1. Do not use NICHIAS fluoropolymer products for any applications other than those

specified in their brochures.

2. Use NICHIAS fluoropolymer products within the temperature ranges specified in their

brochures.

3. If their (reference) maximum service temperatures are exceeded while NICHIAS

fluoropolymer products are being processed, cracked fluorine-containing gases are

generated. Ensure adequate ventilation. Be careful not to inhale cracked gases.

4. Do not weld NICHIAS fluoropolymer products or bring flames near them. Otherwise,

they can fail or leakage may result.

5. Before using NICHIAS fluoropolymer products, read their SDS (Safety Data Sheet)

carefully.

6. Dispose of NICHIAS fluoropolymer products correctly in compliance with relevant laws

of the country.

Considerations before use

Before using NICHIAS fluoropolymer products, please consider

their characteristics as described below.

1. The technical (product performance) data provided in the product brochures are

measured or representative values from experiments (and are not guaranteed values).

Consider this carefully before starting to use the product for a particular application.

2. Applications in which acid, alkaline or highly toxic fluids are used require even more

careful consideration regarding precaution “1” above. Please contact us for technical

advice.

3. Fluoropolymer, which is used in NICHIAS fluoropolymer products, can fail under

repeated, highly concentrated or bending load. Please consider this carefully with

respect to the actual working environment before starting to use the product.

4. Fluoropolymer products do not require lubrication but are subject to wear. Therefore,

regular replacement is recommended when they are used in locations of continuous

wear.

5. Fluoropolymer, which is used in NICHIAS fluoropolymer products, can harden, suffer

dimensional change or allow fluids to permeate or pass through it under certain

working conditions. Please consider this carefully regarding the actual working

environment before starting to use the product.

For questions or advice, please contact our sales or technical department.
