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 application 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

Frequently Asked Questions (FAQ)
What is the difference between GPPS and HIPS grades?
GPPS (General Purpose Polystyrene), such as GON525 and GON535N, is highly transparent and rigid, ideal for crystal-ware and XPS foam. HIPS (High Impact Polystyrene), such as GON825, features high impact resistance and is commonly used for toys, housing, and structural parts where durability is required.
Which grade is best suited for transparent household packaging?
GON525 is highly recommended for transparent applications due to its high transparency and good processability. It is widely used in refrigerator crispers, kitchen containers, and chocolate boxes.
Can GON535N be blended with other polymers?
Yes, GON535N is suitable for blends with high impact polystyrene (HIPS) to improve heat contact performance and impact resistance. It can also replace SAN and PMMA in applications like water filters.
What are the primary applications of GON825?
GON825 is a high-impact grade designed for injection molding. Common applications include office, kitchen, and bathroom articles, food packaging (cups and dairy containers), and consumer electronics housings.
Which polystyrene grades are suitable for XPS/PSP foaming?
Grades such as LIWAN 525, LIWAN 535N, GON525, GON535N, STL525, and STL535 are ideal materials for physically or chemically foamed high-quality articles like foam containers and profiles.
