WHAT IS HDPE REGENERAL?

1. What is HDPE recycled plastic pellets?
► The full name of HDPE recycled plastic is High Density Popyethylene. Product created from polymerization from high density ethylene in low pressure environment. Combined with catalysts such as Chromium, Silloc Catalyts,... Recycled from collected plastic wastes with primary HDPE material or itself. For example, plastic cans, packaging, household appliances of all kinds, hot steam pipes, specialized pipes for the postal industry, fiber optic cables, drainage pipes, etc. Products made from recycled HDPE plastic are available. Long service life, not rusty or corroded by acids and salts.
► This line of materials has the most popular colors of white, transparent and slightly translucent. Other colors can be mentioned such as red, black, yellow, white, clear white, milky white, green, blue, etc. Recycled HDPE plastic pellets are often used to produce environmental protection products such as: trash cans, household appliances, plastic packaging, plastic cans, etc. In which, two colors milky white and black are often used in the production of all kinds of items. For example, seat belts, nylon bags, caps of hats, etc. Yellow and red colors of recycled HDPE plastic combine to form chicken intestines. The remaining colors will be used to blow nylon bags such as blue, green, red, ...

2. Specifications of recycled HDPE plastic
There are different types of recycled HDPE plastic. They are also used for different production purposes. Examples include extrusion, spinning or blown film. In this article, Tan Hung plastic beads will choose one of the commonly used HDPE resins to provide technical parameters for readers' reference. Below are the specifications of HDPE HDI0661U1.
► The melting rate (190°C/2.16 kg) of HDPE is 6.20 g/10 min. The melting rate test method is ASTM D1238.
► Density of HDPE 0.961 g/cm3. The density test method of HDPE is ASTM D792.
► Surface tension is 33.6 MPa. The surface tension test method is ASTM D638.
► The tensile strength is 24.4 MPa. The test method for tensile strength of HDPE plastic is ASTM D638.
► Temperature: 1810 MPa. The test method for ductility is ASTM D790.
► The bearing capacity is 4.7 kJ/m2. The test method for resistance to impact is ISO 180/A.
► The deformation temperature of HDPE is 79˚C. The test method for the strain temperature of HDPE is ASTM D648.

3. Properties of HDPE recycled plastic pellets
HDPE recycled plastic pellets have the following outstanding characteristics:
► The most important and valuable property of HDPE is its extremely high strength, resistant to the destruction of liquid solutions. For example concentrated acids, alkalis, salts, acid rain, etc.
► Does not conduct electricity, conduct heat. Do not allow air and water to penetrate the surface.
► Glossy and flexible surface.
► In addition, HDPE recycled plastic can also withstand heat and ultraviolet rays from direct sunlight.
► Regenerated HDPE has good heat resistance: HDPE remains unchanged in pressure compared to other pipes even when the temperature s below -40˚C. This plastic also has very good fire resistance when igniting only at a temperature of 327˚C. Recycled HDPE pipes can also be bent into many shapes. At the same time, they are also less affected by external forces.

4. Application of recycled HDPE pellets
HDPE is a type of engineering plastic that is used in many fields. It is also widely used in daily life.
► As a raw material for the production of household appliances: cutting boards, floor mats, shelves for dishes, ..
► This is the source of raw materials to produce all kinds of water pipes in the model of hyonic agricultural farming system.
► Application in exporting some types of plastic bottles, plastic boxes. As a raw material in the heat blowing method to produce plastic bottles and plastic boxes. These plastic bottles and boxes can all be recycled and reused easily. Great material for single-use products.
► Production of toys for children. With non-toxic properties and UV resistance, HDPE plastic is used to produce toys. Toys made from HDPE still retain the ability to resist harmful effects from ultraviolet rays. It is also very safe for children.
► As raw materials in the industry of manufacturing containers, tanks for industrial chemicals. A common chemical product such as: Household cleaning products, shampoos, conditioners, washing powders, shower gels, antifreeze, .. These types of products do not affect the structure of HDPE plastic. . Therefore, HDPE is often used as a raw material for the production of bags, barrels or tanks for these products.
► Application in plastic pipe manufacturing industry. Due to its good resistance to ultraviolet rays, HDPE pipes are often used in irrigation and outdoor water transportation systems. Thereby, limiting the possibility of the pipeline being cracked or broken due to long-term exposure to the effects of the weather environment.

5. Advantages and disadvantages of recycled HDPE plastic
Advantages of HDPE recycled plastic
► HDPE is light in weight but has the ability to withstand large amounts of weight. This is why car manufacturers often use fuel tanks made from HDPE. Aim to reduce the weight of the vehicle and increase the fuel efficiency of the vehicle.
► Have good impact resistance.
► High durability and resistance to weather changes.
► Resistant to corrosion, mold, insects and rodents. Therefore, this resin is extremely suitable for making underground plastic pipes for transporting and supplying water.
► Can easily create various shapes due to its high flexibility. Covering the common ability of all plastics is malleability.
► Waste plastics can be recycled and reused easily. As a result, it contributes to reducing the production of new plastic products by up to 50%.
Disadvantages of HDPE recycled plastic
► The surface of HDPE is difficult to bond and adhere.
► When the ambient temperature is high, the plastic surface will have a large expansion effect.
► If the temperature changes suddenly, abnormally, it can lead to cracking of the plastic surface.
► There are no flame retardant compounds in HDPE recycled plastic. As a result, it will easily burn if it comes into interacting with fire.
