Polystyrene (PS) Plastic Injection Molding
Retlaw Industries produces high-quality custom Polystyrene parts and components for a wide range of applications across industries. Polystyrene (PS) is a synthetic thermoplastic polymer made from styrene and is one of the most used materials in plastic injection molding. Polystyrene (PS) is non-toxic and odorless making it the predominant plastic of choice for businesses in the food packaging and automation industries.
What is Polystyrene (PS) Plastic?
Polystyrene (PS) is a synthetic thermoplastic polymer made from styrene. PS is considered an excellent electrical insulator and offers impressive chemical resistance properties. The solidity and clarity of PS make it useful for everything from electronics and plastic utensils to automotive parts and more. The SPI code (resin identification code) for Polystyrene is 6 and is found inside a triangle consisting of three arrows on PS packaging and containers.
Why is Polystyrene So Commonly Used?
Polystyrene is commonly used in many industries because it is an inexpensive material with valuable mechanical properties. PS can take a solid or foam form and does not react with other materials (inert). Considered an easy material to work with because it shrinks less than other injection mold plastics, PS can be used for a wide range of applications. Common polystyrene products include disposable coffee cups, plastic food boxes, plastic cutlery, and packing material.
Polystyrene (PS) Material Characteristics
Polystyrene is lightweight, hydrophobic, and easy to form into various shapes, making it a common plastic material used in everyday items. The melting point for PS ranges from 240 degrees to 270 degrees Celsius, which is considered relatively low when compared to other thermoplastics. Known for its chemical stability, PS does not react with other materials easily. Polystyrene can be reused and is highly recyclable. Some of the most notable benefits of PS include:
- Resistance to bacterial growth
- Resistance to moisture
- Lightweight
- Provides insulation
- Durable
- Recyclable
