Recycled plastic pellets are produced from the repeated recycling of virgin plastic pellets or from the same material stream. For example: Plastic waste will be classified and go through the process of crushing, cleaning, heating and pressing into fibers to produce recycled plastic. Currently, recycled plastic pellets are divided into 5 common types, namely: HDPE recycled plastic pellets, PP, PE, PVC and ABS recycled plastic pellets.
The physical properties of recycled plastic will be stable and quite tough. In addition, recycled plastic from HDPE material can resist the impact of strong acids or salts, has a long service life and does not rust in humid environments. Because of the production stage and origin, recycled plastic is cheaper than virgin plastic.
In the opposite direction, virgin plastic beads are produced from long-term petroleum distillation. In particular, the original virgin plastic will be white. Therefore, manufacturers can combine additional color additives without affecting their chemical composition or physical structure. Basically, primary plastic beads have quite high elasticity combined with flexibility and the ability to adapt well to environmental temperatures.
That is why they are widely used in the medical field, food packaging production or other health-related fields. This proves that the price of virgin plastic beads is definitely higher than recycled plastic and may be slightly higher than bioplastic. Just like recycled plastic beads, primary plastics are also divided into many common types such as: PET, PP or ABS.
In addition, although the two plastic materials are different in physical and chemical properties, they can both combine well with plastic additives to improve characteristics and develop specialized features in each field.
Recycled plastic resins play a role in the strategy of green economic development as well as environmental protection of the global plastic industry. Therefore, the advantages of this material line are many and diverse. As follows:
In general, recycled plastic pellets can be recycled many times, but the quality will also be slightly affected and the impurity content will likely gradually increase.
First, durability is the strong point of recycled plastic beads. Because they go through many stages in the production process from grinding, cleaning, melting to shaping.
Besides, price is also a decisive factor in the consumption and popularity of recycled plastic particles. Input materials for recycled plastic can be plastic waste, virgin plastic or other types of plastic. Therefore, they not only meet economic and profit criteria but also ensure environmental sustainability and stability.
In addition, recycled plastic pellets also have very good plasticity, typically like PE recycled plastic pellets. Therefore, they also possess quite stable tensile strength if subjected to force for a short period of time. PE recycled plastic pellets are often used in the field of food packaging and water blowing pipes production.
The next advantage of recycled plastic pellets is the ability to conduct electricity stably, such as PVC recycled plastic pellets. The resistivity coefficient of this material is greater than 1013 Ω.cm. Not only that, recycled plastic pellets are produced in many colors and sizes, and their flexibility in many fields is higher than virgin plastic pellets.
Recycled plastic resins not only have sustainable plasticity but also heat resistance. They are also highly appreciated for this advantage when they can withstand up to about 200 degrees Celsius. Therefore, this is also a suitable choice for heavy industries.
In the opposite direction, recycled plastic beads also have some weaknesses as follows:
Although it can be recycled many times, the yield and quality of the material will certainly be reduced and severely affected by impurities from the input fuel. Recycled plastic pellets have not very good durability, products made from this material will easily have surface scratches if they encounter strong impacts during use.
Depending on the different types of input plastic, specific weaknesses of recycled plastic granules in general will form. For example, PVC recycled plastic beads will be hard and quite brittle, they are not flexible like PE or PP plastic. Besides, ensuring the quality of input materials as well as the production process of recycled plastic pellets will take longer and more complicated than virgin plastic.
Unlike recycled plastic, primary plastic is distilled from petroleum fractions and undergoes a thorough filtering process. Virgin plastic pellets also bring many advantages to businesses and customers. As follows:
In general, virgin plastic beads have flexible properties, can withstand large curvatures and pressure if subjected to strong force for a long time. In addition, elasticity is also a perfect plus point for virgin plastic beads.
In particular, virgin plastic is only white immediately after production, but this has helped it increase its aesthetic value when it has a glossy, smooth surface and bright colors. To change the color according to market needs, manufacturers will combine color additives.
In addition, virgin plastic beads also have good durability and are easy to shape during the long-term production process. Therefore, their flexibility will also be higher than recycled plastic beads. For each different type of plastic, virgin plastic will also possess different advantages. Specific examples are:
PP virgin plastic beads are heat resistant between 1300 and 1700 degrees Celsius. In addition, virgin plastic will be odorless, colorless and extremely safe for consumers' health.
PA virgin plastic beads are capable of withstanding strong impacts for a long time. Not only stable heat resistance, this type of virgin plastic also has good chemical durability as well as stable electrical insulation. In particular, PA plastic in general and PA virgin plastic beads in particular can resist the intrusion of chemicals from the outside environment and are safe for food. Therefore, virgin plastic beads from PA plastic are commonly used in the field.
Or virgin plastic beads from ABS are commonly used in the electrical field because they are waterproof, have stable heat resistance and electrical insulating properties. In particular, virgin plastic is licensed to be used to create children's toys because they do not have a plastic smell or become deformed or discolored when exposed to high temperatures.
Besides the advantages, virgin plastic beads also have some disadvantages. First, virgin plastic beads are considered quite difficult to decompose after being discharged into the environment. Besides, if you use it incorrectly during production or use, it can lead to poisoning. Like other plastic materials, virgin plastic beads are also recommended not to be sucked or swallowed.
