Product Description

Product Description

LDPE is defined by a density range of 0.918–0.939 g/cm³. It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. It can withstand temperatures of 80 °C continuously and 95 °C for a short time. Made in translucent or opaque variations, it is quite flexible, and tough but breakable.

LDPE has more branching (on about 2% of the carbon atoms) than HDPE, so its intermolecular forces (instantaneous-dipole induced-dipole attraction) are weaker, its tensile strength is lower, and its resilience is higher. Also, since its molecules are less tightly packed and less crystalline because of the side branches, its density is lower. LDPE contains the chemical elements carbon and hydrogen.

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.

Application

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

· Food storage and laboratory 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, whose "cardboard" is actually 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
