Chemical Properties
Chemical and physical properties are markedly affected by increasing density, which is affected by the shape and spacing of the molecular chain.
Low-density materials have highly branched and widely spaced chains, whereas high-density materials have comparatively straight and closely aligned chains.
Licowax PE 520 is soluble in organic solvents at temperatures higher than 200°F.
Licowax PE 520 is insoluble at room temperature.
Licowax PE 520 is hydrophobic, permeable to gas, and has high electrical resistivity.
Licowax PE 520 have excellent electrical resistance and resistance to water and to most chemicals. Medium molecular weight polymers are waxes miscible with paraffin wax, and polyethylene polymers whose molecular weights are higher than 10,000 are the familiar tough and strong resins that are flexible or stiff.
By varying the catalyst and methods of polymerization, properties such as density, crystallinity, molecular weight, and polydispersity can be regulated over wide ranges.
Polymers with densities ranging from approximately 0.910 to 0.925 g/cm3 are low-density polyethylenes; those with densities ranging from 0.926 to 0.940 g/cm3 are medium-density polyethylenes; and those with densities ranging from 0.941 to 0.965 g/cm3 and higher are high-density polyethylenes.
As the crystallinity or density increases, the products generally become stiffer and stronger and have a high softening temperature and high resistance to penetration by liquids and gases.
At the same time, they lose some of their resistance to tear and environmental stress cracking.
Licowax PE 520 is a chemically pure, porous plastic implant material that can perform supportive functions.
Licowax PE 520 has good tissue biocompatibility and permits ingrowth of connective tissue with related vascularization.
Licowax PE 520 is being used more frequently in nasal surgery.
Polyethylene can be cross-linked by irradiation (electron beam, gamma, or X radiation) or by free radical catalysts such as peroxides.
Uses:
Licowax PE 520 is used in the development of plastics.
Hot melt coating for paper, additive in cast moldings, candles, oil-based inks and hot melt adhesives.
Definition
Licowax PE 520 is a flexible waxy translucentpolyalkene thermoplastic made in avariety of ways producing a polymerof varying characteristics.
In the ICI process, 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 formula weight up to 3 000 000, softeningaround 130°C.
The low-density polymeris less crystalline, being more atactic.
Licowax PE 520 is used as aninsulator; it is acid resistant and iseasily moulded and blown.
Licowax PE 520 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.
Licowax PE 520 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.
In 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).
Uses:
Licowax PE 520 is a thermoplastic polymer consisting of long hydrocarbon chains.
Licowax PE 520 is used in a number of applications including flexible film packaging produced by the blown film process.
Licowax PE 520 is used to regulate viscosity, suspension properties, and general stability in cosmetic formulations.
Typical applications included specialty injection molded parts, in these fields Polyethylene has a wide range of uses:
Injection and blow molded toys, housewares and lids.
Injection molded car seats, mower parts and pails.
Injection molded, thin-walled containers and housewares.

Industrial uses
Licowax PE 520 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.
Licowax PE 520, 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.
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.
Licowax PE 520 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 Licowax PE 520 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.
Licowax PE 520 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.
Production Methods
Licowax PE 520 is produced by a low-pressure solution or gasphase process that is initiated by a variety of transition metal catalysts.
The most common catalysts are Ziegler titanium compounds with aluminum alkyls and Phillips chromium oxide-based catalysts.
The gas-phase and slurry processes are used to produce high molecular weight, high-density (HMW-HDPE) products.
The highest density Licowax PE 520 can be made from an α-olefin comonomer, typically octene for the solution process and butene or hexene for the gas-phase process.
Licowax PE 520 does not have long-chain branches and is therefore more crystalline.
The short-chain branches found in linear PE serve as tie molecules, which give the higher α -olefin copolymers improved puncture and tear properties.
Included in the linear PE family are ultra-low-density PE (ULDPE), LLDPE, and HDPE.
Licowax PE 520’s main use is in blow-molded products such as milk bottles, packaging containers, drums, car fuel tanks, toys, and houseware.
Film and sheet are widely used in wrappings, refuse sacks, carrier bags, and industrial liners.
Injection molding products include crates, pallets, packaging containers, houseware, and toys.
Extrusion grades are used in pipes, conduit, wire coating, and cable insulation.
Licowax PE 520 is a thermoplastic that in many applications replaces its predecessor, low-density polyethylene (LDPE), or is used in blends with LDPE.
In particular, LDPE’s shortchain branching gives it higher tensile strength, puncture, and anti-tear properties, making it especially suitable for film applications.
