1, LDPE Description

 Low-density polyethylene (LDPE) is a thermoplastic made from petroleum. It was the first grade of polyethylene.

2, Chemical resistance

Excellent resistance (no attack) to dilute and concentrated acids, alcohols, bases and esters Good resistance (minor attack) to aldehydes, ketones and vegetable oils Limited resistance (moderate attack suitable for short-term use only) to aliphatic and aromatic hydrocarbons, mineral oils, and oxidizing agents Poor resistance, and not recommended for use with Halogenated hydrocarbons.

3, Applications

LDPE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic bags for computer components, and various molded laboratory equipment. Its most common use is in plastic bags. Other products made from it include:

Trays and general purpose containers Corrosion-resistant work surfaces Parts that need to be weldable and machinable Parts that require flexibility, for which it serves very well Very soft and pliable parts Six pack rings Juice and milk cartons is made of liquid packaging board, a laminate of paperboard and LDPE (as the water-proof inner and outer layer), and often with of a layer of aluminum foil (thus becoming aseptic packaging). Parts of computer hardware, such as hard disk drives, screen cards, and optical disc drives Playground slides Plastic wraps
