- Features and Benefits
- Cannot be tribocharged when properly grounded - Prevents build-up of static charge and accumulation of harmful contamination.
- Electrostatic decay in less than 0.05 second per Federal Test Standard 101C, Method 4046.1 - Results in rapid static dissipation without arcing.
- Surface resistivity of 106 - 108 ohms per square - Provides for ESD control without the need for ionization.
- Permanence in static dissipation performance - Avoids cost of application of temporary topical anti-stats.
- Humidity independent static charge control - Avoids inconvenience of maintaining high levels of humidity and damage caused by such humidity.
- Advanced technology, uniform surface treatment - Avoids charged “hot spots” often found with non-uniform temporary topical anti-stats.
- Superior optical properties - High clarity polyester film with C-300 surfacing means excellent transparency.
- Excellent dimensional stability - Means retention of dimensions over a wide range of conditions.
- High tear and tensile strength polyester film - Results in long term durability.
- Hard, mar resistant, durable surface - Results in long term static dissipative performance.
- Superior chemical resistance - Reduces risk of solvent or chemical surface damage.

TMF-300 Check Film resists tribocharging under all circumstances and cannot generate a charge when properly grounded. This makes it ideal for use in manufacturing and assembly operations for charge sensitive electronic components where it can help prevent both immediate and latent ESD caused defects. Since it resists charge build-up it does not attract contaminants, so it can also help prevent contamination-related rejects in ultra-clean manufacturing operations. Consequently, it is used in the semi-conductor, electronic, micromanufacturing, and mining industries.
TMF-300 Check Film is ideally suited for use as material for quality control templates to check part placement in PC board manufacturing operations. Its surface can be printed with laser printers allowing reproduction of circuit or component diagrams, as well as instructions for testing and assembly procedures. It can also be used in general industrial applications, such as, control of spark discharge in explosive environments. Other applications include; packaging of sensitive electronic parts, membrane switch components, and overlays to protect bar codes.
