Static Dissipative Polyester Plastic Film

Description
TMF-300™ Check Film is a clear film product designed to control static electricity. It is a high tensile, high tear strength polyester film surfaced with SciCron Technologies proprietary, clear, C-300™ static dissipative surfacing. This unique technology prevents charge generation on the film surface, thereby controlling particulate attraction and preventing electrostatic discharge (ESD) events. This performance is permanent and totally independent of humidity. The film also exhibits excellent clarity, toughness, chemical resistance, surface hardness, mar resistance, and dimensional stability.

Applications
TMF-300 Check Film resists tribocharging under all circumstances and cannot generate a charge when proper-ly 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, and micro-manufacturing 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.

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.
