GPPS STL 525

GPPS STL 525 is a premium General Purpose Polystyrene (GPPS) grade designed for applications that require excellent transparency, high rigidity, and consistent processing performance. This grade is widely used in injection molding and extrusion processes where optical clarity, smooth surface finish, and dimensional stability are critical.

STL 525 offers good flow characteristics and high stiffness, enabling smooth processing, precise mold filling, and uniform wall thickness. Its superior clarity and gloss make it especially suitable for consumer and packaging applications where product appearance plays a vital role.

Our Quality Assurance and Shipping Process

Material Guarantee We assure you that the material will meet the specifications of the loading pictures and the sample provided prior to shipment. Customer satisfaction and transparency are our top priorities.

Our Step-by-Step Process

1. Quality Inspection:
• Before finalizing the shipment, our Quality Control (QC) team conducts a thorough inspection of the material to ensure it meets the agreed-upon standards.
• Detailed videos and pictures of the material are captured during the inspection and shared with the customer for approval.
2. Container Booking:
• Once the customer approves the material, a container is booked on the next available vessel to ensure prompt delivery.
• The booking details, including the shipping schedule, are shared with the customer for tracking purposes.
3. Loading and Documentation:
   • Material condition
   • Loading procedure
   • Container and seal numbers
• The material is carefully loaded into the container.
• During loading, we document the entire process with pictures and videos, capturing essential details such as:
• These visuals, along with the draft of the Bill of Lading (BL), are shared with the customer for verification.
4. BL Draft Confirmation:
• The customer reviews and confirms the BL draft.
• Based on the confirmation, the Original Bill of Lading (OBL) is issued.
• A copy of the OBL is then shared with the customer.
