Packaging is one of the main uses of polystyrene foam, but there are different types of packaging depending on the properties of polystyrene. It is important to know some of the differences between these polystyrene, namely General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS).
General purpose polystyrene, also known as GPPS, is a material prepared from styrene monomer polymers. It is a solid, transparent product made by suspension. It is also known as transparent polystyrene, which is very different from high-impact polystyrene (HIPS).
GPPS are fluent. General purpose polystyrene has very low production costs, can be easily stored, and can be easily molded. These features make GPPS products versatile and recyclable. In addition to meeting FDA standards, it is low-cost, X-ray resistant, odor-free and odor-free, and easy to process. Since GPPS are easy to mold, they can be used for closed products such as toys, CD boxes, coat hangers, plastic cups, IT equipment, jewelry boxes, etc.
High impact polystyrene, on the other hand, has impact resistance, but costs are not naturally transparent or transparent. It can be easily coated and glued. It is economical and easy to manufacture, but generally more expensive than the GPPS.HIPS have a matt finish and are the preferred material for hot forming. A common use of HIPS are yogurt cups.
While there are some differences between high-resistance and general-purpose polystyrene resins, they do share several characteristics. Both are low cost, rigid and easy to process and manufacture resins. These processes include injection molding, extrusion, blow molding and thermoforming.
In recent years, with the expansion of GPPS and HIPS market demand, recycled PS pellets have also entered the production industry. As a leading supplier of recycled GPPS in China, INTCO recycling provides recycled PS pellets at affordable price and guaranteed quality. We hope to serve more foam product manufacturers.
