Density
HIPS is characterized by a medium density, typically ranging from 1.03 to 1.06 g/cm³. On the other hand, HDPE is classified as a high-density material, with a density typically ranging from 0.941 to 0.965 g/cm³. This indicates that HDPE is denser than HIPS.

Strength
When it comes to strength, HIPS (High Impact Polystyrene) and HDPE (High-Density Polyethylene) exhibit different characteristics. HIPS is known for its good impact resistance, which means it can withstand sudden impacts without breaking or fracturing. Meanwhile, HDPE boasts excellent tensile strength. It can withstand significant amounts of tensile stress without deforming or breaking.

Temperature Resistance
Regarding temperature resistance, there are notable differences between HIPS and HDPE.
HIPS has a limited resistance to high temperatures. It begins to soften and deform at relatively low temperatures, typically around 70-80°C (158-176°F). Therefore, it is not suitable for applications that involve exposure to elevated temperatures or thermal stress.
In contrast, HDPE exhibits good resistance to a wide range of temperatures. It can withstand both high and low temperatures without significant deformation or loss of properties. HDPE has a relatively high melting point, typically around 120-130°C (248-266°F), which allows it to maintain its structural integrity in demanding temperature conditions. It also has good resistance to cold temperatures, making it suitable for applications in freezing environments.

Chemical Resistance
HDPE boasts excellent chemical resistance across a wide range of substances. It is highly resistant to acids, alkalis, solvents, and many other chemicals. Additionally, HDPE's resistance to chemical degradation contributes to its longevity and durability in harsh environments.
HIPS offers moderate resistance to chemicals and solvents. While it can withstand exposure to certain common household and industrial chemicals, it may not be suitable for highly corrosive or aggressive substances..

Moisture Resistance
HIPS has moderate moisture resistance, while HDPE excels in moisture resistance. HIPS can withstand brief exposure to moisture but may be affected by prolonged exposure or immersion. Whereas, HDPE is highly impermeable to water and maintains its structural integrity and dimensional stability even in wet environments.

Weatherability
HDPE has a high level of UV resistance, which means that it can withstand fading and degradation of color brought on by prolonged exposure to the sun. In a variety of weather conditions, such as intense heat, cold, and humidity, HDPE also keeps its mechanical qualities and structural integrity.
Conversely, HIPS provides a moderate level of weather resistance. Even though it can tolerate exposure to sunlight and mild weather, long-term exposure to UV rays and other harsh environmental factors may eventually cause color fading, surface degradation, and a reduction in mechanical properties.

Processing method
HIPS can be processed using injection molding, extrusion, and thermoforming. Injection molding produces precise parts, while extrusion creates continuous profiles or sheets. Additionally, thermoforming shapes heated HIPS sheets using molds or vacuum forming.
Rotational molding, blow molding, and injection molding are methods for processing HDPE. Rotational molding forms large, seamless, and durable items by heating powdered HDPE in a rotating mold; injection molding creates precise shapes; and blow molding produces hollow products, such as bottles.

Applications
HIPS is commonly used in packaging, consumer goods, and signage, including food containers, toys, and signage materials. Its impact resistance and rigidity protect products during transportation.

HDPE is commonly recycled into various products, including plastic bottles, pipes, and containers. It is also more resistant to chemical degradation and has a longer lifespan compared to HIPS. 

Polymerization
The process begins with the polymerization of styrene monomers using a catalyst such as benzoyl peroxide. This process involves the addition of the monomers to a reactor vessel containing the catalyst and a solvent, followed by heating and agitation to initiate the reaction.

Mixing
Once the polymerization is complete, the resulting polymer is mixed with additives such as impact modifiers, stabilizers, and pigments to enhance its properties and appearance.

Extrusion or Injection Molding
The HIPS resin is then extruded or injection molded into the desired shape and size. Extrusion involves melting the HIPS pellets and pushing them through a die to form a continuous shape, such as a sheet or film. Injection molding involves melting the HIPS pellets and injecting them into a mold cavity under high pressure to form a specific shape.

Cooling and Cutting
After the extrusion or injection molding process, the HIPS material is cooled to solidify it and then cut into the desired length or shape.
Finishing: Finally, the HIPS product may undergo further processing such as trimming, polishing, or surface treatment to achieve the desired finish and properties.
