PROPERTIES
We proudly manufacturer world’s most popular plastic that is HDPE. We are leading HDPE sheet suppliers offering extremely versatile sheets and comes in a variety of sizes. It can be used for a number of various indoor and outdoor applications. It works exceptionally under high temperature and friction. Values remain high when compared to those of many other thermoplastic materials, especially at low temperatures.
APPLICATIONS
Mechanically ground HDPE resins are used to rotationally mold large, complex shaped products such as fuel tanks, trash containers, dump carts, pallets, agricultural tanks, highway barriers and water and waste tanks for RVs. Additionally, HDPE sheet is often extruded with a pebble finish and is used as a cutting board in a variety of industry markets such as meat packing, butchering, and more.
