HDPE sheets can be cut with tools that many people already have. If you treat it like wood you will be successful in cutting and drilling it. The best result for circular or panel saws is carbide teeth. Standard router bits and jigsaw blades also work well for cutting curved or other geometric profiles. The tool blades need to be sharp for best results.
Sani-Armor HDPE sheets are formulated with sub-zero service in mind to maintain impact strength and flexibility. It is important that correct installation methods be used when installing HDPE sheet to ensure you do not introduce stress into the sheet. For high impact at extremely cold temperatures please refer to our Mach Polymer sheet.
HDPE sheet is produced from resin that has a water absorption rate of virtually zero, meaning it does not soak up water or other fluids. Due to these properties, HDPE works as well totally submerged under water, as it does out of water.
Indoor applications experience little to no expansion as the temperature is constant. For outdoor ambient temperature applications, the rule of thumb is that a 4 x 8 sheet will expand as much as 1/2" in length from a hot summer day to sub-zero winter temperatures in cold climates. HDPE sheet expands more in length than in width, due to its molecular structure.
The easiest formula to use for an exact expansion / contraction dimension is as follows:
0.00011 x degree variance(°F) x length in inches
Example: 0.00011 x 30°F temperature change x 96" long sheet = 0.3168" or approximately 5/16"
0.00019 x degree variance(°C) x length in inches
Example: 0.0001 x 16.7°F temperature change x 96" long sheet = 0.3173" or approximately 5/16".
While these numbers may seem high, expansion can be easily negated by using correct installation techniques.
One of the key benefits of an HDPE sheet is that dirt and grime cannot grab hold of it, therefore a simple warm/hot soapy water solution will usually do the job. For tougher cleaning jobs a chemical solution may be used. Although HDPE is very chemical resistant, refer to the chemical chart to verify compliance.
No, HDPE sheets are produced with a closed cell structure polymer. This means it will not absorb liquids, but also means that paint or stain will not adhere to it.
Typically most HDPE will break down and fade quickly outdoors. Our Sani-Armor HDPE sheet is developed specifically for full sun and harsh weather climates.
