TMF-300 ESD Control Check Film
Static Dissipative Polyester  Plastic Film

Description
TMF-300  ESD Control Check Film is a clear film product designed  to control static electricity for a wide range of end uses. It is a high tensile, high  tear strength polyester film surfaced with SciCron Technologies proprietary,  clear, C-300 static dissipative surfacing. This unique C-300 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. TMF-300 ESD Control  Check Film exhibits excellent  clarity, toughness, chemical resistance, surface hardness, abrasion resistance, and dimensional stability.

Applications
TMF-300 ESD Control 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  semiconductor, electronic, and micro-manufacturing, industries. It is ideally  suited as material for quality control templates to check component placement in PC board manufacturing operations.  Its surface is printable allowing reproduction of circuit or component diagrams as well as instructions for assembly and testing operations.  Other applications include; packaging of ESD sensitive electronic components, membrane switch components and overlays to protect bar codes.

Features and  Benefits
Cannot be tribocharged when properly grounded - Prevents buildup 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. 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 conductive  discontinuities (charged "hot spots") often found with non-uniform temporary  topical anti-stats. Superior optical properties - High clarity polyester film with C-300  surfacing provides excellent transparency. High tear and tensile strength polyester film - Results in long term durability. Superior chemical resistance - Reduces risk of solvent or chemical  surface damage.

PRECAUTIONS:
1. Polyester is a combustible thermoplastic.  Observe fire precautions appropriate for comparable forms of wood and paper.
2. Clean with soap and water. Do not use abrasives. Avoid inappropriate  contact with solvents.
