LDPE (Low Density Polyethylene)

As might be expected, this higher crystallinity permits use at temperatures up to 130 C degrees with somewhat better creep resistance below that temperature. Low density polyethylene has less stiffness than the high density type. Blends of the two types are common. TYPICAL APPLIIONS: Toys, utensils, films, bottles, pipe and processing equipment.

This property of plasticity, often found in coination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products.

The History of High Density Polyethylene (HDPE) – Plastic

Erhard Holzkamp invented high-density polyethylene (HDPE). The process included the use of alysts and low pressure, which is the basis for the formulation of many varieties of polyethylene compounds. Two years later, in 1955, HDPE was produced as pipe. For his successful invention of HDPE, Ziegler was awarded the 1963 Nobel Prize for Chemistry.

PEX Information

PEX pluing, PEX fittings, PEX tools. PEX (or crosslinked polyethylene) is part of a water supply piping system that has several advantages over metal pipe (copper, iron, lead) or rigid plastic pipe (PVC, CPVC, ABS) systems.It is flexible, resistant to scale and chlorine, doesn''t corrode or develop pinholes, is faster to install than metal or rigid plastic, and has fewer connections and fittings.

While the industrial development of plastic in many ways made life easier, plastic production impacts every phase of the life cycle. Learn about the harmful effects of plastic on human health and the environment in this excerpt from chapter 2, “Ecology.” Harmful Effects of Plastic

Polyethylene | Chemical Composition and Properties

HDPE (High Density Polyethylene) is defined by a density of greater or equal to 0.941 g/cm 3. HDPE has a low degree of branching and thus stronger intermolecular forces and tensile strength. HDPE can be produced by chromium/silica alysts, Ziegler-Natta alysts or metallocene alysts.

Everything You Need To Know About Polypropylene (PP) Plastic

Polypropylene is a very useful plastic for injection molding and is typically available for this purpose in the form of pellets. Polypropylene is easy to mold despite its semi-crystalline nature, and it flows very well because of its low melt viscosity. This property significantly enhances the rate at which you can fill up a mold with the material.
