The most popular types of plastic beads today
Today, the plastic industry is growing extremely rapidly and has great potential in the future. Due to the large demand, the supply of raw materials could not keep up with this growth. Therefore, businesses are now directly involved in the production of plastic beads instead of importing them with high cost.
In fact, the production process of plastic beads will depend on different types of plastic beads, the most common include two types:
- Recycled plastic pellets: Produced from collected plastic such as PP, HDPE, ABS, PE, PVC... then sorted and recycled by different methods. This recycled plastic pellet is most commonly used today, as a raw material for production in industry, construction, etc.
- Primary plastic granules: Is pure plastic granules without doping, without additives. Including types such as ABS, PC, HIPS, PMMA, POM, PA... Products made from primary plastic have superior properties such as flexibility, good elasticity, resistance to warping pressure, bright colors , smooth glossy surface with high aesthetics.
The most modern production process of plastic beads
Using modern machinery and equipment helps the production process of plastic granules take place quickly, with high quality of finished products. Therefore, this is considered an extremely effective method to help save costs of importing plastic beads from abroad and lower product costs and increase competitiveness.
Production process of recycled plastic beads
- Step 1: Collect used plastic
- Step 2: Sort and cut the collected plastic into small pieces
- Step 3: Clean the plastic to remove dirt and then dry it
- Step 4: Bring the cleaned plastic to melt and press through the extruder into recycled plastic fibers or beads.

Production process of virgin plastic beads
Compared with the production of recycled plastic beads, primary plastic pellets have a more complicated production process including:
- The hydrocarbon will be heated and undergo a "cracking" process to break down into ethylene and propylene.
- Next, low-molecular-weight compounds must undergo polymerization to create polymer resins.
- Adding dyes, plasticizers, flame retardants, etc., after the cracking process is over, will form polymers to make various products. And polyvinyl chloride and styrene are substances used to make primary plastic beads.
In addition to having good quality, non-toxic, and impurity-free primary plastic beads, a modern and error-free production line is needed.
Through the above article, I hope you know more about the most popular plastic resin production processes today.
