Product Specifications and Features of Plastic Resin Pellets

Technical Specifications

Plastic resin pellets come in divergent specifications depending on their intended use. Key parameters include:

• Density: This refers to the mass per unit volume of the plastic resin pellets. It typically ranges between 0.3 to 1.2 grams per cubic centimeter (g/cm³). The density of the plastic resin pellets affects the strength and buoyancy of the end product.
• Melting Point: The melting point of plastic pellets generally ranges from 160°C to 250°C. It largely depends on the type of resin. For example, polypropylene has a melting point of about 160–170°C. On the other hand, ABS requires around 220–240°C to melt.
• Water Absorption: Plastic resin pellets have low water absorption values. Normally, they range from 0.1% to 0.5%. However, this property varies with the type of resin. Low water absorption ensures the stability of the plastic material even in humid conditions.
• Packaging: Plastic resin pellets are usually packed in 25 kg up to 1000 kg bulk bags. Sometimes referred to as supersacks. Manufacturers also package them in smaller paper sacks or plastic bags for retail distribution. This makes it easily accessible for small businesses or workshops.

How to Install

The melting process of plastic resin pellets relies on the type of resin and the manufacturing equipment. During the process, the pellets are usually heated to the specified melting temperature. This makes them pliable for shaping. Below is a description of the process of using plastic resin pellets. It varies across applications:

• Injection Molding: In injection molding, the pellets are first fed into a hopper. The hopper then transports the pellets to a heated barrel. Here the pellets are melted and mixed. A screw then forces the molten resin into a mold cavity. The resin then cools and solidifies into the desired part. This process is commonly used in manufacturing automotive parts and consumer products.
• Extrusion: In extrusion, the pellets undergo a similar melting process. The molten resin is then forced through a die to produce continuous shapes. Such shapes include films, pipes, and rods. This method is ideal for producing long products with consistent profiles.
• Blow Molding: Blow molding uses melted resin pellets to manufacture hollow containers. The pellets are melted and formed into a tube which is then inflated within a mold. This process leads to the creation of bottles and tanks.
• 3D Printing: In 3D printing applications, such as fused deposition modeling (FDM), the pellets are extruded through a heated nozzle. This produces 3D printed objects layer by layer. This method offers high precision and is excellent for prototypes.

Maintenance

Maintenance of products made from plastic resin pellets largely depends on the type of resin used and the end application. However, general maintenance practices include cleaning, inspection, and repair. These practices enhance the lifespan of the plastic components.
