Polystyrene

Wanpeisi Factory is equipped with advanced production equipment and a technical team that strictly adheres to international quality standards, ensuring that the polystyrene products produced are stable and reliable. This material is widely popular due to its lightweight, transparency, insulation, and good moldability, and is widely used in the manufacturing of transparent packaging materials, transparent containers, display racks, mechanical parts, and electrical insulation parts. Despite the relatively low heat resistance of polystyrene, its low cost and environmental friendliness make it a highly competitive choice in the market.

Wanpeisi Factory rigorously implements a series of production processes, relying on advanced production equipment and a strict quality management system to ensure that the quality and performance of polystyrene products meet the high standards of customers. Our production process begins with the polymerization reaction, which transforms styrene monomers into polystyrene by heating the reactor under high or normal pressure. Sometimes, a pre-polymerization step is also conducted to enhance the polymerization efficiency and molecular weight distribution of the product. After post-processing, polystyrene granules can be further processed into various shapes through molding techniques such as injection molding, blow molding, and extrusion molding to meet the needs of different application fields.

Polystyrene Product Characteristics

Polystyrene (PS) is a thermoplastic widely used in various industries, and it is highly favored for its unique physical and chemical properties. This material is renowned for its excellent transparency, lightweight characteristics, good electrical insulation, and chemical stability at room temperature.

Chemical Stability: At room temperature, polystyrene exhibits its outstanding chemical inertness, showing significant tolerance to a range of chemical substances and is not prone to reacting with them.

Processability: Polystyrene demonstrates exceptional processing flexibility, capable of being easily shaped and transformed into various complex and intricate forms through advanced techniques such as injection molding and blow molding, meeting the needs of different industries.

Cost-effectiveness: Among the various plastic materials, the production cost of polystyrene is relatively economical, which makes it the material of choice for manufacturing disposable products and is widely used in various fields of daily life.

Chemical Stability: Polystyrene displays excellent chemical inertness under normal temperature conditions, with outstanding tolerance to a variety of chemical reagents, and is not likely to react with them, ensuring the versatility and safety of its applications.

Hygroscopicity: Polystyrene has a very low hygroscopic nature, barely absorbing moisture from the surrounding environment, which makes it particularly suitable for use in dry conditions, maintaining the stability and reliability of the products.

Polystyrene product applications

Fast food boxes are mostly made from polystyrene material, which is highly favored in the fast food industry for its high transparency, light weight, excellent thermal insulation, and low cost. It has a certain oil resistance and meets food safety standards, making it very suitable for holding various hot and cold foods. Polystyrene fast food boxes are designed for single-use, aiming to provide a convenient and quick solution for food packaging.

Polystyrene as a 3D printing material offers an affordable and easy-to-process option. It occupies a place in the field of 3D printing thanks to its excellent fluidity, appropriate viscosity, and rapid solidification characteristics. Polystyrene 3D printing materials are commonly supplied in the form of filaments or powder and can be used to precisely print complex geometries and detailed structures through technologies such as fused deposition modeling (FDM) or selective laser sintering (SLS).

The use of polystyrene in the manufacture of shells for electronic products such as computers and televisions not only enhances the safety and appearance of the products but also effectively reduces production costs, fulfilling consumers’ expectations for the aesthetic and functional aspects of electronic products. Additionally, the heat-insulating properties of polystyrene offer extra protection for the internal components of electronics, shielding them from damage caused by high temperatures.

In terms of material, these medical supplies are generally made of glass or plastic (such as polystyrene). The plastic petri dishes are transparent, making them easy to observe. With their precise design, durable materials, and wide range of applications, these medical supplies have become indispensable tools in the laboratory, providing solid support for scientific research and medical testing.
