Recycled polyethylene granules

Recycled polyethylene granules

Recycled polyethylene granules are obtained from the recycling of waste of this group of polymers. Polyethylene is one of the most widely used polymers in the world. Proper processability is one of its important characteristics. Different grades of polyethylene are produced, each of which has a different molecular weight. Recycled polyethylene granules are usually known as inflatable granules, pipe granules and hash granules.
Recycled polyethylene can be used in the production of household and kitchen items. Of course, it should be said that its preparation can be much cheaper than other plastics. Other cases that can be used for this widely used granule are nylon bags and some bottles and three-dimensional car floors.

Air grade high density polyethylene granule is often referred to as inflatable granule. Granule obtained from the recycling of plastic gallons such as car oil gallons, various pots, detergent bottles, milk bottles, etc.
The customers of pneumatic granules are mainly factories whose final products are of the same type. For this reason, their coloring is extremely important. For this purpose, it is necessary to use the necessary care from the very beginning, that is, the waste separation stage.
For the sale of inflatable granules, factories that produce industrial gallons, plastic bottles, nylon and plastic parts can be targeted.

Film grade low density polyethylene granules are the same granules that are used to produce film as well as plastic nylons. His recycled granules are produced using the waste of all kinds of nylons. This granule should be clean and free of impurities. Therefore, in its production process, automatic washing lines and filters with high mesh are used in the granulation machine.
For the sale of polyethylene film granules, transparent packaging nylon manufacturers can be considered. Of course, they use colorless, transparent and high-quality granules for this purpose. In addition, in the production of store colored nylon, they use light honey granules. The next customer of his granules are the manufacturers of black garbage bags, for whom the color and transparency of the granules are not so important.

Recycled pipe granules can also be sold to producers of polyethylene pipes, tapes, geomembrane sheets and compounds.

HDPE is one of the easiest polymers to recycle and is accepted in most recycling centers. In America, the recycling rate for this material is about 30%. The purpose of HDPE recycling is to use for non-food containers; Such as detergents, household cleaners, etc. Also, painted HDPE is used in the production of pipes. Pipes used in agricultural fields and other underground pipes can be made from 40% recycled HDPE resin. In some cases, recycled HDPE can be made into other products such as benches and other durable plastic products.

Produced from first-hand inflatable containers that have been milled and washed with hot water to remove any impurities and dirt.
Extruded with mechanized equipment and using an 80 mesh filter to achieve the highest quality in the final product.
Mix and homogenize to achieve the same properties in all parts of the product.

LDPE polyethylene is used to produce plastic bags that are given to people by grocery stores and retailers. Technically, LDPE can be recycled, but as mentioned before, recycling must be economically viable. Products made with LDPE are light and cheap, and their recycling may not be economically justified. Also, plastic bags get tangled in recycling machines, which make the recycling process difficult. Despite these problems, recycled LDPE can be used in packaging films. One of the chemical characteristics of this low-density granule is that it does not react at room temperature. But if it is mixed with strong oxidizing materials, it will cause swelling on this material. The temperature it can withstand is up to 80 degrees Celsius. But its structure is very transparent and has high flexibility. This plastic model produces greenhouse gas when exposed to direct sunlight. In terms of the chemical resistance of low-density plastic granules, its resistance to all kinds of acid diluents and basic solvents can be mentioned. But it has very weak resistance against degradable chemicals and against aliphatic and aromatic hydrocarbons and oxidizing agents.
