GON525
1. Material Characteristics:
GON525 is a highly transparent GPPS grade. It gives excellent mechanical and heat resistance properties while providing with easy process-ability and short cycle time.
2. Material Application:
- Transparent parts for refrigerators such as fruit and vegetable crispers, chillers, flaps, trays etc.
- Stationery products like pen barrels, scales etc.
- Household applications such as crystal-ware, kitchen containers etc.
- Ideal material for physically or chemically foamed high-quality foamed articles, such as foam containers, labels or profiles (PSP/XPS)
- Packaging applications such as chocolate boxes, display cabinets, etc.
- Other transparent articles in injection molding applications
GON535N
1. Material Characteristics:
GON535N is a heat resistant, rapid freezing general purpose grade. It is suitable for expanded sheet and film; for blends with high impact polystyrene in heat contact applications; for transparent, impact resistant applications in blends.
2. Material Application:
- LDP (Light diffuse plate) and LGP (Light guide plate)
- Ideal material for physically or chemically foamed high-quality foamed articles, such as foam containers, labels or profiles (PSP/XPS).
- Replacement of SAN and PMMA in several applications like water filter containers, pen parts etc.
- Extruded molded articles and injection molded articles
- Transparent sheet for showcases & displays, consumer electronics, household application, photo frames, building material etc.
- In blends with high impact polystyrene
GON825
1. Material Characteristics:
GON825 is a medium flow and very high impact Polystyrene (HIPS). It gives good mechanical and heat resistance properties while providing with easy processability and short cycle time.
2. Material Application:
- Wide range of injection molding applications, e.g. - office, kitchen and bathroom articles
- Food packaging as beverage cups, packaging for dairy products, sheets and disposables
- Internal parts and housings of household appliances and consumer electronics
- Toys
Frequently Asked Questions (FAQ)
What is the primary difference between the GPPS and HIPS grades listed?
GPPS (General Purpose Polystyrene) grades, such as GON525 and GON535N, are highly transparent materials with excellent heat resistance, commonly used for optical parts, clear packaging, and XPS foam. HIPS (High Impact Polystyrene) grades, like GON825, offer high impact strength and medium flow, making them ideal for structural housings, toys, and impact-resistant food packaging.
Which grade is suitable for optical applications like light guide plates (LGP)?
GON535N is specifically designed for optical components like Light Diffuse Plates (LDP) and Light Guide Plates (LGP) because it features a heat-resistant, rapid freezing profile that is suitable for extruded or injection molded transparent sheets.
Can these materials be used for XPS or foamed packaging?
Yes. Both GON525 and GON535N GPPS grades are ideal materials for physically or chemically foamed high-quality articles, such as foamed containers, labels, and profiles (PSP/XPS).
Which grade is recommended for household refrigerator parts?
GON525 is highly recommended for transparent refrigerator parts like fruit and vegetable crispers, chillers, flaps, and trays due to its high transparency and excellent mechanical properties.
What applications are best suited for the HIPS GON825 grade?
GON825 is ideal for injection-molded products requiring impact strength, including office, kitchen, and bathroom articles, toys, consumer electronics housings, and dairy product packaging.
