Fluoroplastic Product: NITOFLON No.900UL

Excellent in chemical resistance, electrical properties and weather resistance; can be used continuously in a wide range of temperatures.

Outline

NITOFLON No.900UL is a polytetrafluoroethylene (PTFE) film with a number of excellent features such as heat resistance, chemical resistance, desirable electrical properties, low friction coefficient and non-adhesiveness.

Features

• Superior chemical resistance; hardly affected by acids such as nitric acid, sulfuric acid, hydrochloric acid and phosphoric acid as well as alkalis including caustic alkali and ammonia.
• Excellent electrical properties such as little dielectric loss, high insulation resistance and breakdown voltage. Both dielectric constant and dielectric loss tangent are minimal while its volume resistance is extremely high that remain stable in a wide range of temperatures and frencies, so it can be used as a high-frency insulating material.
• Continuous use in a wide range of temperature from -100°C to 260°C available.
• Lowest friction coefficient among all solid materials and excellent self-lubricating ability. In combination with fillers, it makes an auto-lubrication bearing with great friction resistance and cold-flow resistance.
• With its non-adhesiveness and mold-releasing property, no adhesive substance attaches to it, and makes mold-releasing easy when it comets into contact with adhesive substance.
• Excellent weather resistance and moisture resistance.
• Superior flame resistance.
