Tyco Plastics Polyethylene Sheeting Spec Sheet
Scope: Covers 2,3,4, 5,6,8, and 10 mil sizes in both black and clear.
Basic Uses: Tyco Plastics' polyethylene sheeting is used in a wide variety of application. Polyethylene provides an excellent vapor barrier for the protection of concrete slabs and foundations. Proper placement of poly sheeting in walls during construction can almost completely prevent ambient air and moisture infiltration into homes and buildings, thus increasing their energy efficiency. Agricultural applications (black sheeting only) include retention of soil moisture, inhibition of weed growth, and coverage of pit and trench silos for inexpensive storage.
Life Expectancy: Clear sheeting is not recommended for greenhouse use or any other application involving long-term exposure to sunlight. Black sheeting is recommended for application not exceeding 90 days of sunlight exposure. Special additives are available at request for extended outdoor applications up to 2 years.
Shelf Life: Polyethylene sheeting has a shelf life of approximately 2 years if not exposed to sunlight or extreme heat.
Other Limitations: Check with the vendor for information on these and other limitations that may or may not apply depending on the specific application and product.
Adhesion: Due to the variety of resins and additives available, it is often difficult to bond two pieces of film together. Two adhesives that have proven to be successful in the past are Universal Adhesives' Spray Adhesive and DURO All Purpose Spray Adhesive distributed by Loctite Corporation.
