What Is High-density Polyethylene (HDPE)?
High-density polyethylene which is also known as HDPE is a thermoplastic resin used in the manufacturing of multiple products from plastic jugs to synthetic lumber for the implants for facial reconstructive surgery.
High-density polyethylene is produced by combining ethylene molecules which are commonly derived from natural gas. HDPE is highly recyclable and less harmful to the environment as compared to other plastics. It doesn’t contain BPA, heavy metals, or allergens and it does not release harmful fumes and doesn’t contaminate soil or water. HDPE is among the best environmentally stable plastics.
Is HDPE The Same As PE?
With the advancement in technology, many thermoplastics have been introduced in the industry and more are expected. We have seen many high-quality plastics products in recent times due to impressive thermoplastics. But the difference between HDPE and PE is still a topic of contention in the industry.
The most produced plastic in the world is polyethylene which is a thermoplastics polymer created from ethylene gas. It serves as a base for multiple plastic products. Whereas, high-density polyethylene also known as HDPE is a denser version of polyethylene used in water and drain pipes because of its unique properties like rigidness and crystalline structure. The main point of different HDPE and PE is that HDPE has polyethylene (PE) as its base.
Polyethylene (PE)
Polyethylene in solid form is harmless but it can be toxic in liquid form or when inhaled as a vapor or absorbed through the skin. It is more expensive than polypropylene to make and is considered the second-best choice of material for the production of living hinges.
High-density polyethylene (HDPE)
It consists of inflexible and strong plastic with the color of milk. HDPE has a high impact and melting and can resist cracks. You can find HDPE in chemicals, food, beverages, and personal care packaging. Shampoo bottles, bleach bottles, soap containers, milk jugs all are made from HDPE plastic. It is easily recycled and it takes approximately 8 to 10 milk jugs to make a pound of HDPE plastic when recycled.
Is HDPE Easy To Machine?
HDPE has several industrial applications and is also easy to machine with good rigidity, high tensile strength, impact resistance, and low moisture absorption. It is an excellent material for CNC machining with the properties such as:
Good resistance against chemicals, corrosion, impact, and solvents.
Has high melting point which is 266° F (130° C)
Has high strength to density ratio
Better tensile strength than LDPE
While considered good for CNC machining operations, it can also pose some challenges when machined under the wrong conditions. Some of the things to keep in mind while machining HDPE are:
Annealing the HDPE before the machining operation can reduce the risk of cracking and other damages.
High processing speed is needed when routing and milling high-density polyethylene (HDPE).
Chips produced during machining operations can clog the machine. A good vacuum system can clear the chips and deliver close tolerance and good surface finishing.
HDPE can also be used as 3D printing containers for some chemicals. HDPE is widely used for tooling, prototyping material, fixturing, and casings.
Is HDPE Better Than UHMW?
High-density polyethylene (HDPE) has some of the features and properties that shadows the Ultra-high molecular weight polyethylene (UHMW) and vice versa. To decide which one is better is totally depends upon the applications of the parts you are going to manufacture with these materials. We have gathered some differences that can clear the air regarding the difference between these two. It can also help you to decide on selecting the material for your project.
HDPE (high-density polyethylene)
It is a durable, versatile, abrasion and chemical-resistant plastic material. HDPE is easy to fabricate and weld through thermoplastic welding equipment. It is considered an excellent choice for water tanks and chemical tanks.
UHMW (ultra-high molecular weight polyethylene)
It is an extremely tough, low-cost plastic with an abrasion resistance that is used for a number of wear applications. UHMW is a priority for the countless industries that require durability, chemical resistance, and low friction in their applications. Its applications are wear strips, chain guides, dock fender pads, and marine docks.
What Is HDPE Plastic Used For?
Due to HDPE’s impressive properties and impeccable machineability, it is a highly used plastic across the globe in many industrial and consumer applications. It is commonly used in cutting boards, conveyor liners, and food handling equipment. Other than this it is also used in many other industries, let’s have a look at some of the industrial applications of HDPE.
Medical Industry
It is often used in the medical industry due to its excellent chemical resistance and it does not absorb moisture. Along with these properties, it is non-toxic which makes it useful for medical containers. Some formulations of HDPE that contain certain plastic additives are also antibacterial.
Chemical Industry
Having high chemical resistance and weldability, HDPE became the material of choice for the manufacturing of the bottles, containers, tanks for the chemical products. Corrosion-resistant liner is also produced with the help of HDPE. It is also compatible with low concentration acids, several alcohols and bases, and alkalis.
Construction Industry
It is also popular in pipe manufacturing industries and used in construction for the piping system. As discussed earlier, high-density polyethylene does not absorb water and is easily welded, this makes it the perfect material for lightweight, durable, and rigid piping systems for construction.
Maritime Industry
Seaboard is the formulation of the HDPE which is used in designing the boat components and pool equipment such as seats, benches, handles, and doors. Because it is effective in UV resistance, this material provides a longer lifetime.
Food Industry
Many high-density polyethylenes comply with the FDA and other European standards that make it an approved material for direct contact with food. Sanalite, an HDPE formulation specifically created for the food industry. It is almost exclusively used for durable and easy to clean cutting boards. Agromur is also another HDPE formulation used for the design of wall panels.
What Are The Advantages Of HDPE Machined Parts?
High-density polyethylene is vastly used thermoplastics that has many advantages such as excellent chemical resistance and good rigidity. Let’s have a wider look at some of the prominent advantages of high-density polyethylene.
High Resistance to Chemicals
It is considered the ideal material for the manufacturing of storage containers for food, chemical products, and liquids. It maintains its properties when it comes in contact with chemicals and is thus considered safe in food containers.
Lightweight and Strong
High-density polyethylene (HDPE) is a lightweight but strong material. For example, the HDPE milk jug container can weigh only two ounces but it can carry a gallon of milk.
UV Resistant
If the product is used for outside applications, UV resistance of that product is essential property because that can ensure the optimum service life of the product. HDPE has several UV-resistance formulations which makes it ideal for outdoor usage.
Good Weldability
HDPE can easily be welded. The good weldability makes it useful for larger projects such as watertight tank liners used for storing volumes of liquid.
Does Not Absorb Moisture
HDPE does not absorb moisture even if it is exposed to fluid for a longer period of time. This property is essential and makes it the best choice for the designing of storage tanks and other products.
Are HDPE Parts Friction-resistant?
HDPE is a material with low friction. HDPE is not considered best for friction-resistant applications. As there are many other plastics that have better friction than HDPE. If we compare it with UHMW, the coefficient of friction of HDPE is 0.20 which is higher than that of UHMW which is 0.08. This makes UHMW more suitable for applications that require a reduction of friction.
Are HDPE Parts Resistant To High Temperatures?
All kinds of plastic start to melt at a certain temperature. The shape of the plastic starts to change and it becomes soft when it reaches its melting point when you heat the plastic. Our topic of concern here is how much temperature can high density polyethylene (HDPE) can bear?
HDPE is resistant to temperature for a certain level but when the temperature reaches 70C/1580F it starts to soften and when temperatures cross 130°C it starts to melt. But remember one thing here, HDPE films start to soften evenly which makes HDPE ideal for thermoforming, heat sealing, bending, and other applications.
What Technologies Are Suitable For Machining HDPE?
HDPE is a high-impact, high-density crystalline thermoplastic used in everyday home appliances and commercial containers. Making these appliances and other parts from HDPE to use in our applications is only possible through CNC machining of HDPE.
HDPE is available in sheet stock, rods, and other shapes which makes it a good option for subtractive machining such as CNC milling and turning. There are many suitable techniques for machining HDPE but the most trusted and accurate method is CNC turning and milling.
CNC Turning
This process is used for creating symmetrical and cylindrical features by machining HDPE. Typically HDPE bar is held in a chuck and rotated at high speed while a cutting tool is positioned against the workpiece (HPDE) to remove the material and get the desired part. This method is very efficient for high production runs and when you need the same part in large numbers.
CNC Milling
This method is employed when there is no cylindrical feature is required. In this process, the HDPE is held stationary and the rotating cutter will come in contact with the workpiece (HDPE) and remove the unwanted material to turn it into the desired shape. In 2 and 3 axis milling machines the workpiece is manually rotated while in 4 and 5 axis machines can automatically rotate the workpiece and spindle. 4 and 5 axis milling machines are used for complex shapes and contours.
