Polystyrene (PS) includes ordinary polystyrene, expanded polystyrene (EPS), high impact polystyrene (HIPS) and meta-polystyrene (SPS). Ordinary polystyrene resin is non-toxic, tasteless, colorless transparent particles, quasi-glassy brittle materials, its products have high transparency, light transmittance of up to 90%, good electrical insulation performance, easy coloring, good processing fluidity, good rigidity, good chemical corrosion resistance and other characteristics. The disadvantages of ordinary polystyrene are brittleness, low impact strength, easy to appear stress cracking, poor heat resistance and boiling resistance.
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.

Plastic particles are widely used, such as household, agriculture, industry, business and so on,include injection/blowing/extrusion/etc.
Polystyrene is easy to process and has the advantages of transparency, low cost, good rigidity, insulation and good printability. Can be widely used in lighting market, daily decoration, lighting instruction packaging and so on. In the electrical aspect, it is a good insulating material and thermal insulation material for the production of various instrument shells, lamp shades, optical chemical instrument parts, transparent films, capacitor dielectric layers, etc.
Can be used for sorting and lotion cosmetics. Compact bodies have good compressibility. The adhesive properties of the powder can be improved. It gives the skin a feeling of lightness and lubrication and is an advanced filler to replace smooth petrochemical powders and silica.
