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 primary difference between GPPS and HIPS resins?
GPPS (General Purpose Polystyrene) offers high clarity, transparency, and rigidity, making it ideal for clear displays and packaging. HIPS (High Impact Polystyrene) includes added rubber compounds to deliver superior impact resistance and toughness for durable housings and structural parts.
Which polystyrene grade is best recommended for optical and light guide applications?
GON535N is specifically optimized for light diffuser plates (LDP) and light guide plates (LGP) due to its high heat resistance, rapid freezing properties, and outstanding optical clarity.
Can GPPS materials like GON525 replace other transparent plastics?
Yes, high-clarity grades like GON525 and GON535N can cost-effectively replace polymers like SAN and PMMA in applications such as water filter containers, stationery parts, and transparent household items.
What makes GON825 suitable for home appliance housings and toys?
GON825 features a balanced medium melt flow rate combined with very high impact resistance and heat stability, ensuring durable finished products with shorter injection molding cycle times.
