LINING MATERIALS
...Permalon Ply X-210, the least expensive lining material, is a four layer composite laminate of three layer co-extruded polyolefin film. The material is composed of twelve distinct layers. This high density, cross-laminated poly is designed to be UV resistant by a state of the art stabilization system. When exposed to harsh weather conditions, including intense sun, X-210 should last in excess of five years. When buried, this material should last indefinitely. Permalon maintains its strength and flexibility in cold temperatures well below Oº. Permalon Ply X-210 is chemically inert, non-leachable and is resistant to root penetration, rodents and microbials (it is not a food source). Additionally, it meets ASTM D-3083 (Soil Burial). Ply X-210 is not prone to stress-cracking (ESC), thus, making it a very good moisture and Radon barrier. UV stabilized to help protect from the deteriorating effects of direct sunlight.
Factory seams are made using a thermal/pressure fusion technique that is performed under controlled conditions. This seaming method produces 2" wide seams that are both watertight and stronger than the parent material. Should field seaming be necessary, two methods have been evaluated and found acceptable. The first is by a portable seaming unit that produces the same type of seams as produced by the factory. The second method of field seaming is called "extruded welding". This method employs a machine that uses a bead of melted plastic to fuse and seal the sheets together. Again, it is important to note that field seaming be kept to a minimum as factory prefabrication both of large sheets and three dimensional shapes is possible.
The manufacturer of the material certifies that, to the best of their knowledge, Permalon Ply X-210 meets the FDA requirements for Indirect Food Additives and for GRAS (Generally Recognized as Safe) under FDA-HFF-335 title 21 Code of Federal Regulations, Sections 177.1500 to 177.2000, inclusive. These regulations recognize that Permalon is suitable for use in containment of and as packaging for food products.
Permalon Ply X-210 is an extremely light-weight material, weighing approximately 80 pounds per 1000 square feet of material.
This material is suited for a wide array of applications such as landscape pond liners, stockpile covers, storm retention pond liners, waste lagoon liners, contaminated soil covers, equipment covers, daily landfill covers and final closures for landfills.
...PVC is a near homogeneous mixture of poly (vinyl chloride), plasticizers, ultra-violet inhibitors, fillers and other additives. The properties of vinyl are directly related to the amount of plasticizers; more plasticizers will produce softer the vinyl. Over time, ultra-violet light and other environmental factors cause the plasticizers to slowly migrate from the material. As a result the vinyl will loose its elasticity. Initially, however, vinyl is softer and more pliable than polyolefin film and, consequently, is easier to mold to the contours of your tank or pond. Another advantage of PVC over polyolefin film is the ability to do field seaming with adhesive. Field seaming should be kept to a minimum since it produces inferior seams compared to factory seams.
PVC, 30 to 32 mil, is most often recommended for small ponds simply because it is readily available, easy to work with, easy to repair and a good value.
This material is suited for a wide array of applications such as tank liners, pond liners, spa liners, swimming pool liners, waterbed mattresses, air mattresses, air conditioner covers, etc.
HYPALON
...Hypalon is a laminated, reinforced, uncured synthetic rubber. We stock 36 mil but it is also available in 45, 60 and 90 mils thick. It scuffs very easily in the first six months after it is manufactured and is susceptible to blocking (sticking to itself) when exposed to direct sunlight in a folded condition. A surface cross-linking develops as it ages which produces a stronger liner with more weatherability. It is virtually immune to ozone and ultraviolet light. A very, very tough material, recommended for larger, deeper ponds.
EPDM
...EPDM, 45 mil, is a cured synthetic rubber. It is a superb general-purpose pond liner material. It is extremely flexible and conformable and has extraordinary resistance to extreme temperature variations from intense desert heat to arctic cold. Slightly more expensive than PVC but cheaper than Hypalon and Butyl rubber. Material be special ordered in 60 mil and/or fabric backed.
BUTYL
...Butyl rubber is formulated substantially from expensive butyl polymer with little filler material and this makes it a very expensive product to produce in comparison to EPDM or Hypalon. It has extraordinary resistance to moisture transmission and biological decay, as well as exceptional elasticity. It can be custom ordered in either 30 or 40 mil thickness.
