Plastic Foam Pelletizing Line | EPE Styrofoam Pelletizing Machine

泡沫塑料造粒线是专为泡沫塑料回收造粒而设计的解决方案。近年来，泡沫在包装行业得到广泛应用，但其体积较大，运输困难。这带动了泡沫回收和再利用机械设备的快速发展。随着新技术的不断采用，发泡聚苯乙烯回收机的设备技术和生产效率普遍得到快速提高。

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.

发泡聚乙烯

发泡聚乙烯是一种由聚乙烯聚合物制成的结构泡沫。它是通过加热和压缩聚乙烯聚合物以形成气泡而制成的，使其重量轻、柔韧，并具有隔音和隔热性能。它主要用于包装、建筑和家庭应用。

发泡聚苯乙烯

EPS（即发泡聚苯乙烯）是一种轻质、刚性的热电偶材料，由聚苯乙烯小颗粒制成。 EPS 因其成本低、多功能性和良好的绝缘性能而常用于绝缘、包装和保护性缓冲应用。

为了制造 EPS，聚苯乙烯小颗粒与丙烷等充气机混合，然后加热并模制成大块。充气机在颗粒内部形成小气泡，使它们膨胀并形成有机体。根据所需的应用，可以控制膨胀过程以生产具有不同密度和物理特性的 EPS。

Process Flow of Plastic Foam Pelletizing Line

破碎——结块——拉丝——冷却——造粒

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.
