High-density polyethylene HDPE is among the most common types of plastic worldwide. Some HDPE products may be food grade, while others are not appropriate for food storage. Boasting a fairly high recovery rate, HDPE is also one of the most recycled plastics. Once HDPE has been used and recycled, it has a wide range of uses in still more widely used products. It is a linear polymer. Because there is no branching in the structure of the plastic, it is more dense and opaque than other plastics and can withstand somewhat higher temperatures.

HDPE, a lightweight, non-toxic material, is one of the most common varieties of plastic in the world. Inthe global HDPE market reached a total of 30 million tons. According to the American Chemistry Council, HDPE has moisture barrier properties, which makes it a perfect fit for use in many packaging applications.

HDPE may be used in film and in blow-molded-bottle and injection-molded-bottle form in a wide range of products. Common uses of HDPE include snack food packages; cereal box liners; milk and non-carbonated beverage bottles; margarine, whipped topping and deli food packaging; and bread trays. In addition, HDPE has chemical resistance attributes, so it is often used in bottles and packaging for industrial chemicals, household cleaners and detergents.

It is worth noting that not all products bearing the HDPE recycling symbol are food-grade. However, as a rule, containers sold at restaurant supply stores and ice chest interiors are food grade. If you are unsure whether or not the container is food grade, contact the manufacturer. Most municipal recycling programs accept HDPE products. While many types of plastic have low recovery rates, byrecycling technologies for HDPE milk and water bottle recycling had reached 28 percent efficiency.

Most curbside programs collect several types of plastic resin, and HDPE is one of the most common. Recycling HDPE is critical, as it can reduce the amount of plastics that ultimately end up in landfills and decrease the amount of natural resources used in producing virgin plastic products. It is important to identify HDPE products correctly to avoid cross-contamination, keep down the costs of collecting and reprocessing recyclables and keep recycled plastic market values high.

Even after HDPE has been recycled, it is still appropriate for a wide range of uses.We do not broker or trade low end contaminated recycled plastic. Our extensive process is hands on with an extraordinary amount of effort and care that goes into each and every box.

We aim for zero returns and happy, productive customers. Our goal is to supply the material you save to run on the night shift where the need is great for smooth and seamless production. This allows us to manufacture a consistent quality product without the odors or contaminates associated with the average PCR that is in the market today.

Then each box is probed looking for foreign materials, paper, and foaming agent. A team member will take a probed sample from the top, middle, and bottom section of each box. Our lab technicians then test the regrind in our certified melt index equipment to confirm the melt flow is accurate and to look for changing conditions in the resin that might surface once it has melted.

After passing the first two parts of our quality control procedures, the material is moved to the metal removing equipment. At this point, the regrind is dumped through a magnet system while being watched by our trained technicians for any strange looking material that could be hiding in the box. If found, it is tested on our Perkin Elmer FT-IR spectrometer to confirm it is not a foreign resin and a melt index is tested to ensure consistency.

In this final stage of the process, the regrind is vacuumed into a Kice Aspiration System where the fines and paper are removed from the regrind and is packaged in a quality Gaylord box with a liner and a lid. The box is then weighed on a certified scale. HDPE is the sturdiest and most inflexible type of polyethylene within polyethylene applications. HDPE is defined by a having a density greater than or equal to. HDPE offers excellent impact resistance, lightweight, low moisture absorption, and high tensile strength.

Additionally, HDPE is also non-toxic and non-staining. Phase 2 A team member will take a probed sample from the top, middle, and bottom section of each box.

Phase 3 After passing the first two parts of our quality control procedures, the material is moved to the metal removing equipment. Phase 4 In this final stage of the process, the regrind is vacuumed into a Kice Aspiration System where the fines and paper are removed from the regrind and is packaged in a quality Gaylord box with a liner and a lid.

Product Qty.Many kinds of polyethylene are known, with most having the chemical formula C 2 H 4 n. PE is usually a mixture of similar polymers of ethylene with various values of n.

Polyethylene is a thermoplastic ; however, it can become a thermoset plastic when modified such as cross-linked polyethylene. Polythene are divided mainly into two types:- 1. Low density polyethyleneand 2. High density polyethylene. Polyethylene was first synthesized by the German chemist Hans von Pechmannwho prepared it by accident in while investigating diazomethane. The first industrially practical polyethylene synthesis diazomethane is a notoriously unstable substance that is generally avoided in industrial application was again accidentally discovered in by Eric Fawcett and Reginald Gibson at the Imperial Chemical Industries ICI works in NorthwichEngland.

Because the reaction had been initiated by trace oxygen contamination in their apparatus, the experiment was difficult to reproduce at first. It was not until that another ICI chemist, Michael Perrindeveloped this accident into a reproducible high-pressure synthesis for polyethylene that became the basis for industrial low-density polyethylene LDPE production beginning in The landmark breakthrough in the commercial production of polyethylene began with the development of catalysts that promoted the polymerization at mild temperatures and pressures.

The first of these was a chromium trioxide —based catalyst discovered in by Robert Banks and J. Paul Hogan at Phillips Petroleum. The Phillips catalyst is less expensive and easier to work with, however, and both methods are heavily used industrially. By the end of the s both the Phillips- and Ziegler -type catalysts were being used for high-density polyethylene HDPE production.

In the s, the Ziegler system was improved by the incorporation of magnesium chloride. The Ziegler- and metallocene-based catalysts families have proven to be very flexible at copolymerizing ethylene with other olefins and have become the basis for the wide range of polyethylene resins available today, including very low density polyethylene and linear low-density polyethylene.

Such resins, in the form of UHMWPE fibershave as of begun to replace aramids in many high-strength applications. The properties of polyethylene can be divided into mechanical, chemical, electrical, optical, and thermal properties.

Polyethylene is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction. It shows strong creep under persistent force, which can be reduced by addition of short fibers.

It feels waxy when touched. The commercial applicability of polyethylene is limited by its low melting point compared to other thermoplastics.

HDPE is used in marine applications such as boating seats and floors when covered from UV lightscabinetry, counter tops and walkways.

Storage Applications Its light weight, durability, flexibility and toughness make HDPE a great solution for many storage applications including bottles, bottle caps, food storage containers, bins, laundry detergent bottles, and water cans. Fuel tanks for vehicles, plastic bags, storage sheds, and lawn and garden products are also produced from HDPE plastic. Due to its high chemical resistance, HDPE is used to make geomembranes for hydraulic applications such as canals and bank reinforcements and chemical containment.

Piping Systems HDPE has the durability and chemical resistance to make it an ideal plastic solution for many piping systems including chemical resistant piping systems, corrosion protection for steel pipelines, geothermal heat transfer piping systems, water pipes for domestic water supply, and agricultural processes.

Industrial Industrial industries all over the nation use HDPE plastic to produce tough and durable products such as mechanical parts, tank linings and wear strips. These products rely on the impact resistance and super tensile strength of HDPE products, which make them more durable and reliable.
