A linha de pelotização de espuma plástica é uma solução projetada para reciclagem e granulação de espuma plástica. Nos últimos anos, a espuma tem sido amplamente utilizada na indústria de embalagens, mas é grande e difícil de transportar. Isto levou ao rápido desenvolvimento de máquinas e equipamentos para recuperação e reciclagem de espuma. Com a adoção contínua de novas tecnologias, a tecnologia dos equipamentos e a eficiência da produção das máquinas de reciclagem de poliestireno expandido têm sido geralmente melhoradas rapidamente.
Introduction of Plastic Foam Pelletizing Line
The plastic foam pelletizing line efficiently recycles waste foam via compacting, crushing, heating, melting, extrusion, and pelletizing, which features high output, low energy consumption, stable operation, suitable for polystyrene, etc., turning scraps into reusable pellets to boost resource utilization and environmental protection.
Expanded polystyrene pelletizing machine for plastic foam recycling is an integrated industrial system designed to recycle waste plastic foam into reusable plastic pellets. This process transforms low-value, bulky foam waste into high-quality raw materials for new plastic production. The line typically combines mechanical crushing, thermal melting, and pelletizing technologies to achieve efficient material recycling, addressing both environmental pollution and resource scarcity challenges.
Raw Materials and Finished Products of Plastic Foam Pelletizing Line
A linha de pelotização de espuma plástica pode produzir grânulos de plástico a partir de resíduos de espuma reciclados.
Polietileno Expandido
O Polietileno Expandido é uma espuma estrutural feita de polímeros de polietileno. É fabricado aquecendo e comprimindo o polímero de polietileno para formar bolhas de ar que o tornam leve, flexível e com propriedades de isolamento acústico e térmico. É usado principalmente em embalagens, construção e aplicações domésticas.
Poliestireno expandido
EPS, ou poliestireno expandido, é um material leve, rígido e termopar feito de pequenos pellets de poliestireno. O EPS é comumente usado para aplicações de isolamento, embalagem e amortecimento protetor devido ao seu baixo custo, versatilidade e boas propriedades de isolamento.
Para fabricar EPS, pequenas partículas de poliestireno são misturadas com um inflador, como o propano, e depois aquecidas e moldadas em grandes blocos. O inflador forma pequenas bolhas dentro dos pellets, fazendo com que eles se expandam e formem um organismo. Dependendo da aplicação desejada, o processo de expansão pode ser controlado para produzir EPS com diferentes densidades e propriedades físicas.

Process Flow of Plastic Foam Pelletizing Line
Britagem – aglomeração – estiramento – resfriamento – pelotização
The plastic foam pelletizing line is 100% available for recycled foam. EPS EPE foam is compressed and then pelletized, making it the most widely recycled processing method. The foam is compressed or thermally melted by a professional foam compressor, which results in a compressed block. The shredded foam compressed blocks can be used for pelletizing to produce high-quality EPS EPE pellets. It can be applied to the production of new foam products. Now, with the growing popularity of carbon emission reduction, recycling has become the primary method for regenerating EPS.
There are some differences between EPE and EPS pelletizing in the EPE EPS foam granulating line. EPE foam is soft and the granulator to process this kind of foam usually contains an automatic feeding device. Also, the EPE foam doesn’t need a crusher for pre-processing, so it can be directly into the granulator.
EPS foam is usually large size, which means EPS foam needs to be shredded by a crusher and compacted. As a result, this kind of foam can enter the granulator for processing.

Applications of Recycled Plastic Pellets
O material EPE EPS é amplamente utilizado nos seguintes campos devido às suas propriedades leves, elásticas, à prova de umidade, à prova de choque e resistentes à corrosão.
- Packaging: It is often used for packaging electronic products, food, cosmetics, industrial, and other items to protect them from damage during transportation.
- Construção: O polietileno espumado é frequentemente utilizado na construção, como divisórias de paredes, isolamento acústico, isolamento térmico, proteção, etc.
- Furniture: It is commonly used in the manufacture of furniture such as sofas, seats, mattresses, pillows, etc., to provide comfort and good support.
- Sports equipment: It is often used for the dry manufacturing of sports equipment such as diving boards, protective gear, etc.
- Electronics: It is often used to dry-manufacture electronic products, such as cell phone cases, computer bags, photographic equipment, etc.
Main machines of Plastic Foam Granulator Line
triturador de espuma plástica
O triturador de espuma plástica é usado para esmagar grandes pedaços de espuma reciclada em pequenos pedaços que podem ser facilmente derretidos e peletizados.
máquina compactadora de espuma
Due to the low density and large volume of the foam, it needs to be compressed by the foam compactor machine after crushing to improve the material transportation efficiency.
Extrusora de espuma plástica
A extrusora de espuma plástica é usada para derreter e extrusar pequenos pedaços de espuma plástica triturada em longas tiras.
Tanque de resfriamento
O tanque de resfriamento é usado para resfriar as tiras de plástico de alta temperatura para endurecê-las e facilitar o corte.
Cortador de grânulos de plástico
O cortador de grânulos de plástico é usado para cortar longas tiras de plástico resfriado e endurecido em pellets de plástico de tamanho uniforme.

EPE EPS Foam Granulating Line Export Case
In 2025, a forward-thinking Mexican plastic recycling firm opted for Shuliy’s SL – 180 EPE Styrofoam Pelletizing Machine. Facing the challenge of handling substantial EPE sheets and foam packaging waste, the client needed an efficient solution to convert this bulky material into valuable pellets. The SL – 180 line, with its 250 kg/h output capacity, robust build, and user-friendly design, proved ideal.
The exported SL – 180 EPE Pelletizing Line with a production rate of 250 kg/h helps the Mexican client boost recycling efficiency, reduce landfill waste, and create a new revenue stream by selling high-quality pellets.
FAQs of Plastic Recycling Machine
What is the typical production capacity of EPE EPS Foam Granulating Line?

If you would like more detailed information, please feel free to contact us.
Can wet foam be pelletized directly in the plastic foam pelletizing line?
No. Moisture causes bubbles in the melt and cracked pellets; it must be dried via hot air or centrifugal dehydration.
Why do pellets discolor?
In plastic foam pelletizing line, possible causes may be extrusion temperature too high (plastic degradation), raw material contamination, or clogged filters. Check temperature control and clean impurities.
