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, because it does not conduct electricity, 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 suitable for food packaging materials. *For more details, please refer to the PDF document or feel free to contact us.
