Pre-expanded polystyrene (pre-EPS) is essentially expanded polystyrene beads that have been expanded or "pre-expanded" before being molded into their final form.

Ever wondered what that lightweight, shock-absorbing material is in your child's new toy airplane or that comfy seat cushion? The answer might be EPP, or Expanded Polypropylene. This versatile material is taking the world by storm, finding its way into an ever-growing range of consumer products due to its unique properties and the efficiency of EPP machines in shaping it.

In the growing field of materials science, Expanded Polypropylene (EPP) has emerged as a versatile and lightweight material with numerous applications. The key to the production of EPP products lies in the specialized machinery used to create and shape this material—the EPP machine. Let's explore the crucial role EPP machines play in the manufacturing process and what they are used for.

Since 2012, NINGBO PinSheng machinery have passed the CE certification of UK and the IS09001-2008 quality management system certification. The company was recognized as a high-tech enterprise and The "Level A of honesty and trustworthiness "honor. The trademark of "Pinsheng" was come to be a well-known brand and demonstration. （China EPS machine)

An EPS machine is a comprehensive system designed for the production of Expandable Polystyrene (EPS) products. EPS is a remarkable material known for its exceptional insulating properties, low weight, and affordability. EPS machines facilitate the creation of a diverse range of EPS products by processing raw EPS material into desired shapes and forms.

EPS foam particles have excellent low temperature resistance (the lowest working temperature can reach -70℃ ~ -100℃) and excellent electrical insulation performance, but polyethylene is sensitive to environmental stress, chemical and mechanical effects, and has poor anti-aging performance. EPS foamed polyethylene is a white waxy translucent material, flexible and elastic, lighter than water, with superior dielectric properties, low water permeability and high organic vapor permeability. Under certain crystallinity, the transparency of polyethylene increases with the increase of molecular weight. Next, let Pinrise introduce you to where EPS foam can be applied:
