Uses

polyethylene is used to regulate viscosity, suspension properties, and general stability in cosmetic formulations. It is derived from petroleum gas or dehydration of alcohol.

Uses

Polyethylene (PE) is a thermoplastic polymer consisting of long hydrocarbon chains. PE is used in a number of applications including flexible film packaging produced by the blown film process. Significant differences in physical properties have been observed in linear low density polyethylene (LLDPE), low density polyethylene (LDPE), and high density polyethylene (HDPE) blown films. Structural parameters, such as density/ crystallinity, molecular weight and its distribution, short chain branching (SCB)/ long chain branching (LCB) length and amount, and crystallinemorphology are the key factors that control the properties. HDPE is the most crystalline PE, since its chains are linear and contain very little branching. There are many intrinsic factors affecting polymer degradation. Such factors include the number of branching of the polymer, the molecular weight, the hydrophobicity/hydrophilicity ratio, the crystallinity, and the morphology of the polymer. There are several publications that study the degradation of PE and the alteration of plastic surfaces in the laboratory or under controlled conditions in the field.

Definition

polyethylene: A flexible waxy translucentpolyalkene thermoplastic made in avariety of ways producing a polymerof varying characteristics. In the ICIprocess, ethene containing a trace of oxygen is subjected to a pressure inexcess of 1500 atmospheres and atemperature of 200°C. Low-densitypolyethene (r.d. 0.92) has a formulaweight between 50 000 and 300 000,softening at a temperature around110°C, while the high-density polythene(r.d. 0.945–0.96) has a formulaweight up to 3 000 000, softeningaround 130°C. The low-density polymeris less crystalline, being more atactic.Polyethene is used as aninsulator; it is acid resistant and iseasily moulded and blown.

Definition

ChEBI: A polymer composed of ethane units.

Uses

Laboratory tubing; in making prostheses; electrical insulation; packaging materials; kitchenware; tank and pipe linings; paper coatings; textile stiffeners.

Agricultural Uses

LDPE is short for low density polyethylene. LDPE sheets are used for lining jute bags in which fertilizers are stored. LDPE acts as a waterproofing material.

Industrial uses

Rigidity and tensile strength of the HDPE resins are considerably higher than those properties in the low- and medium-density materials. Impact strength is slightly lower, as is to be expected in a stiffer material, but values are high, especially at low temperatures, compared with those of many other thermoplastics.
HDPE resins are available with broad, intermediate, and narrow molecular-weight distribution, which provides a selection to meet specific performance requirements. As with the other polyethylene grades, very-high-molecular- weight copolymers of HDPE resins are available with improved resistance to stress cracking.
Applications of HDPE range from film products to large, blow-molded industrial containers. The largest market area is in blowmolded containers for packaging milk, fruit juices, water, detergents, and household and industrial liquid products. Other major uses include high-quality, injection-molded housewares, industrial pails, food containers, and tote boxes; extruded water and gas-distribution pipe, and wire insulation; and structural-foam housings.
HDPE resins are also 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 recreational vehicles.

Industrial uses

LDPE, the first of the polyethylenes to be developed, has good toughness, flexibility, low-temperature impact resistance, clarity in film form, and relatively low heat resistance. Like the higher-density grades, LDPE has good resistance to chemical attack.
One of the fastest-growing plastics is linear LLDPE, used mainly in film applications but also suitable for injection, rotational, and blow molding. Properties of LLDPE are different from those of conventional LDPE and HDPE in that impact, tear, and heat-seal strengths and environmental stress-crack resistance of LLDPE are significantly higher. Major uses at present are grocery bags, industrial trash bags, liners, and heavy-duty shipping bags for such products as plastic resin pellets.

Industrial uses

Polyethylene thermoplastic resins include lowdensity polyethylenes (LDPE), linear low-density polyethylenes (LLDPE), high-density polyethylenes (HDPE), and ethylene copolymers, such as ethylene-vinyl acetate (EVA) and ethylene- ethyl acrylate (EEA), and ultrahighmolecular- weight polyethylenes (UHMWPE). The basic properties of polyethylenes can be modified with a broad range of fillers, reinforcements, and chemical modifiers, such as thermal stabilizers, colorants, flame retardants, and blowing agents. Major application areas for polyethylenes are packaging, industrial containers, automotive, materials handling, consumer products, medical products, wire and cable insulation, furniture, housewares, toys, and novelties.
Polyethylene is a water-repellent, white, tough, leathery, thermoplastic resin very similar in appearance to paraffin wax. Properties vary from a viscous liquid at low molecular weights to a hard waxlike substance at high molecular weights. It is used as a coating for glass bottles and fiberglass fabrics (special treatments for glass are required to obtain good adhesion between polyethylene and glass) and is also used as an injection-molding material for ceramics.
TIn the polymerization process, the double bond connecting the carbon atoms is broken. Under the right conditions, these bonds reform with other ethylene molecules to form long molecular chains. Ethylene copolymers, EVA, and EEA are made by the polymerization of ethylene units with randomly distributed comonomer groups, such as vinyl acetate (VA) and ethyl acrylate (EA).

Safety Profile

Questionable carcinogen with experimental tumorigenic data by implant. Reacts violently with F2. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Crystallise it from thiophen-free *benzene and dry it over P2O5 under vacuum.
