Nitto 973 UL -PTFE film tape(roll)

NITOFLON No.973UL is a fluoroplastic saturated glass-cloth adhesive tape consisting of a glass cloth base material impregnated with polytetrafluoroethylene (PTFE) dispersion and then sintered, single-surface treated and coated with a silicone adhesive. This construction combines glass cloth's mechanical strength with PTFE's exceptional heat and chemical resistance for the most demanding industrial sealing and masking applications.

Key Features

NITOFLON 973UL is UL510 certified and environmentally compliant with Notification No.20 of Japan's Ministry of Health, Labor and Welfare. The tape offers superior mold-releasing and sliding properties along with good holding capability at elevated temperatures and excellent dimensional stability. Its non-adhesive side exhibits the full range of PTFE characteristics: outstanding electrical properties, resistance to heat, weather, chemicals, and water (water-shedding), plus genuine non-adhesiveness for release applications.

Performance Data

NITOFLON 973UL operates reliably across a working temperature range of -60°C to 200°C, making it one of the most temperature-versatile tapes in Nitto's fluoroplastic range. The glass-cloth-reinforced PTFE construction delivers substantially higher mechanical strength and heat resistance than film-only PTFE tapes, supporting sustained use in heat-sealing and high-temperature processing equipment.

Applications

NITOFLON 973UL is used for heat-resistant insulation, heat-resistant lubrication for heat sealing equipment, chute and hopper linings, surface coating of sizing rolls for dyeing and resin treatment, and general heat-resistant masking and packaging machine applications requiring durable, non-stick, high-temperature performance.

Directions for Use

Apply NITOFLON 973UL to heat-sealing bars, chute linings, or sizing rolls, ensuring the silicone adhesive side bonds securely to the equipment surface. The exposed PTFE-impregnated glass cloth surface delivers reliable non-stick, heat-resistant performance through repeated thermal cycling between -60°C and 200°C.
