HDPE and LDPE Overview

High density polyethelyne (HDPE) sheet features high impact strength, abrasion resistance, and a low coefficient of friction. The material is also moisture, stain and odor resistant, and in many grades is FDA approved to be used in the food processing industry.

The material's durability makes it ideally suited for a variety of applications such as water tanks, chute linings and numerous industrial uses.

HPDE is a very light and extremely tough, chemically resistant plastic and is one of the most commonly used plastics in the United States.

It does not absorb water and has good sliding abrasion resistance in addition to being self-lubricating. High density polyethylene (HDPE) lends itself particularly well to blow molding for bottles, cutting boards, dipping baskets, dippers, trays and containers.

Low density polyethelyne (LDPE) is more flexible than HDPE, which makes it a good choice for prosthetic devices, most of which are either drape formed or vacuum formed.

HDPE Applications

Common application include:

Containers: Fuel tanks for vehicles, laundry detergent bottles, milk jugs, watering cans, bottle caps and bottles

Marine Use: Walkways, cabinetry, counter tops, ship and boat components exposed to outdoor environments

Cutting board: FDA approved cutting boards, food industry and service equipment

• Playground equipment, park and recreational outdoor equipment

• Arena/puck board

• Backpacking frames

• Ballistic plates

• Chemical resistant piping systems

• Coax cable inner insulators (dielectric insulating spacer)

• Corrosion protection for steel pipelines

• Folding chairs and tables

• Hydraulics reinforcements

• Geothermal heat transfer piping systems

• Meter & valve boxes

• Plastic bags

• Storage sheds

• Water pipes, for domestic water supply



What is HDPE versus HDPE XL?

HDPE & Marine Board:

HPDE, or High Density Polyethylene, is a very light and extremely tough, chemically resistant plastic and is one of the most commonly used plastics in the United States. It does not absorb water and has good sliding abrasion resistance in addition to being self-lubricating. High density polyethylene lends itself particularly well to blow molding, e.g. for bottles, cutting boards, dipping baskets, dippers, trays and containers.

HDPE XL:

Interstate Plastics Marine Board XL is a lighter, more economical version of the popular marine board. This 100% virgin polymer, marine-grade cellular material has an excellent surface finish. Black and white are priced the same. Expect 15 day delivery for this item, please. Interstate Plastics Black Marine Board XL sheets are up to 30% lighter in weight than marine board, and are made with the same textured surface and colors for a perfect match. Sheet sizes are 54" wide and 96" long. Black and white are most readily available.

HDPE XL Utility:

King Starlite XL Utility is an economical cellular (closed cell) utility sheet made from select high-grade King Starboard recycled high-density polyethylene. Fabricating and finishing King Starlite XL Utility is easy with standard woodworking tools. King Starlite XL Utility forms easily for smooth curves and bends. Since there is no grain pattern, parts can be cut from any part of the sheet, virtually eliminating waste (meaning greater economy versus wood).
