What is the difference between GPPS and HIPS

GPPS (General Purpose Polystyrene) and HIPS (High Impact Polystyrene) are both types of polystyrene. GPPS stands for polystyrene, and HIPS stands for high impact polystyrene. There is a big difference between them. The editor of Qingdao prime It is summarized for you as follows:    

1. Ingredients and properties:

GPPS: Usually pure polystyrene with no additives. It has a transparent appearance and is more brittle than HIPS.

HIPS: is a modified polystyrene that usually contains a mixture of polystyrene and rubber (usually nitrile rubber). This makes HIPS more resilient and impact-resistant than GPPS.

2. Physical properties:

GPPS: brittle and fragile, transparent in color, often used in transparent plastic containers, CDs, optical lenses, etc.

HIPS: Due to the addition of rubber, HIPS has higher impact strength and toughness, and is usually used to manufacture impact-resistant products, such as TV casings, furniture, home appliance casings, and toys.

3. Processing and use:

GPPS: Easy to process and suitable for processing methods such as injection molding, extrusion molding and blow molding. Often used to create transparent or translucent products.

HIPS: Although it can also be processed by the same processing method, due to its modifying properties, it is more suitable for manufacturing products that require impact resistance, especially those that need to withstand external impact or extrusion.

Overall, the main difference between GPPS and HIPS is their composition and physical properties. The choice of which material to use depends on the specific requirements of the product being manufactured, particularly the need for transparency and impact resistance.
