Basic Knowledge of Plastic: What is PS?

Basic Knowledge of Plastic: What is PS?

Plastic resin produced by polymerizing styrene monomer made from crude oil and naphtha!

As basic knowledge about plastics, we will introduce "PS." "PS" is a plastic resin made by polymerizing styrene monomer, which is derived from crude oil and naphtha (raw gasoline, straight-run gasoline). Broadly speaking, there are two types: general-purpose polystyrene, which is highly transparent and hard, and impact-resistant polystyrene, which is milky white and has improved impact resistance due to the addition of rubber components. In addition, there is syndiotactic polystyrene, which is crystalline and opaque but has excellent heat resistance. [Features] - General-purpose polystyrene (GPPS): Highly transparent and hard - Impact-resistant polystyrene (HIPS): Improved impact resistance with added rubber components - Syndiotactic polystyrene (SPS): Excellent heat resistance *For more details, please refer to the PDF materials or feel free to contact us.

Basic Knowledge of Plastic: Characteristics of PS

Basic Knowledge of Plastic: Characteristics of PS

One of the materials that is easy to recycle! It has excellent dimensional stability during molding.

Here is an introduction to the characteristics of "PS" as basic knowledge about plastics. "PS" is said to be suitable for inexpensive and bulk consumer goods. You might associate it with Styrofoam, but its specific gravity is lighter than that of polypropylene (PP) and polyethylene (PE) among plastic materials. Additionally, it does not conduct electricity, so it can be used as an exterior material for electrical products and as insulating components without special treatment. It is tasteless and odorless, making it suitable for food packaging materials. 【Characteristics】 ■ Contains a benzene structure and is amorphous, offering excellent transparency and rigidity. ■ Relatively stable to heat and has excellent dimensional stability during molding, making it easy to process. ■ Suitable for inexpensive and bulk consumer goods. ■ Tasteless and odorless, making it appropriate for food packaging materials. *For more details, please refer to the PDF document or feel free to contact us.

[Information] Basic Knowledge of Materials - What is Polystyrene?

[Information] Basic Knowledge of Materials - What is Polystyrene?

Introducing basic knowledge about materials related to polystyrene!

Polystyrene (PS) is a hard, colorless, and transparent material at room temperature, with the ability to be easily colored. It is widely used for packaging, including containers for bento boxes and packaging films, and is also commonly used in home appliances such as televisions, air conditioners, and refrigerators, as well as office equipment. For more details, the external link page provides an easy-to-understand explanation of synthetic resin materials. [Excerpted Content] - Polymer of styrene CH2=CHC6H5 - Solid with a density of 1.04 to 1.07 g/cm³ and a softening point of 80 to 100°C - Soluble in benzene, toluene, methyl ethyl ketone, acetate esters, and halogenated hydrocarbons - Insoluble in water, alcohol, and fatty acid hydrocarbons; stable in acids and alkalis - Good electrical insulation properties and excellent high-frequency characteristics *For more information, please refer to the external link page or feel free to contact us.

Basic Knowledge of Plastic: Advantages and Disadvantages of PS

Basic Knowledge of Plastic: Advantages and Disadvantages of PS

High thermal stability during melting and easy coloring! A detailed introduction to the advantages of PS.

As basic knowledge of plastics, we will introduce the advantages and disadvantages of "PS." The advantages include excellent light transmittance and high transparency, superior dimensional stability during molding, ease of coloring, and being tasteless and odorless. On the other hand, the disadvantages include low heat resistance, impact resistance, and oil resistance. 【Advantages】 ■ Excellent light transmittance and high transparency ■ High lightweight properties ■ High electrical insulation and thermal stability during melting ■ Superior dimensional stability during molding ■ Easy to color, tasteless and odorless ■ Excellent weather resistance *For more details, please refer to the PDF document or feel free to contact us.
