Polystyrene (PS), abbreviated as PS, refers to a polymer synthesized by free radical addition reaction of styrene monomer, with the chemical formula (C8H8) n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.

Product application:
Due to its transparency, excellent rigidity, electrical and printing properties, especially its good hygiene and low cost, polystyrene has broad application prospects in food packaging. It has been widely used in various instrument casings, lampshades, optical parts, instrument parts, transparent window mirrors, transparent models, chemical acid storage tanks, acid conveying tanks, telecommunications parts, high-frequency capacitors, high-frequency insulation pads, brackets, inserts, and frozen insulation materials in the electromechanical industry, instrument and communication equipment industry, etc. It is also widely used in various daily necessities, such as bottle caps, containers, decorations, buttons, combs, toothbrushes, soap boxes, boxes, and toys.
The English name for polystyrene is Polystyrene, abbreviated as PS. PS is a thermoplastic non crystalline resin that is polymerized from styrene monomers and can be synthesized through various synthetic methods. In industry, bulk polymerization and suspension polymerization are mainly used. PS is mainly divided into general grade polystyrene (GPPS, commonly known as transparent benzene), impact grade polystyrene (HIPS, commonly known as modified benzene), and foam grade polystyrene (EPS).
General grade polystyrene is a thermoplastic resin that is colorless, odorless, odorless, and glossy, transparent, bead like or granular solid.General grade polystyrene is a thermoplastic resin that is colorless, odorless, odorless, and glossy, transparent, bead like or granular solid. It is soluble in Aromatic hydrocarbon, chlorinated hydrocarbons, aliphatic ketones and esters, but can only swell in acetone. It can withstand the action of certain mineral oils, organic acids, alkalis, salts, lower alcohols, and their aqueous solutions. Low water absorption, able to maintain its mechanical properties and dimensional stability in humid environments. The optical performance is second only to acrylic resin. Excellent electrical performance, high volume and surface resistivity, and unaffected by temperature and humidity changes, as well as corona discharge. The radiation resistance is also very good. Its main drawbacks are brittle and easy to crack, low impact strength, poor heat resistance, and inability to withstand boiling water. It can only be used at lower temperatures and loads. Poor sunlight resistance and flammability. When burning, it emits black smoke and has a special odor.
Polystyrene (PS) plastic is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the
form of a rigid foam material. PS plastic is commonly used in a variety of consumer product applications and is also particularly
useful for commercial packaging.
Polystyrene (PS) for Prototype Development on CNC Machines and 3D Printers: Polystyrene is available in sheet stock, rod stock,
and in various shapes. It is a great candidate for subtractive machining processes on a CNC machine. Colors are usually limited to
clear, white, and black although colors can be added and it is an excellent candidate for external painting.
Polystyrene (PS) for� Injection Molding:
General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS) are probably the most commonly used PS resins for injection
molding. GPPS is clear, but brittle (think of a CD jewel case) while HIPS is opaque and much less brittle.

Application:
HIPS Compound resins are used in a variety of different applications, including:
Packaging� : HIPS Compound is often used to produce packaging products such as food containers, electronics containers, or other packaging products thanks to its impact resistance and flexibility.
Toys� : With good impact resistance properties, HIPS Compound is an ideal material for the production of toys and games for children, ensuring safety and durability during use.
Electronic Device Enclosures� : HIPS Compound is often used to create the outer casings of electronic devices such as computers, printers, televisions and other home appliances, providing an aesthetic appearance and protection for these devices.
Household items� : It is also used in the production of household items such as trays, straws, cups, and other products with requirements for durability and food safety.
Industrial applications� : In industry, HIPS Compound is used in applications such as wall linings, surface protection, or products requiring high flexibility and durability.
Construction materials� : HIPS Compound can also be used in construction applications such as partitions, insulation panels or interior accessories.
