San Lumps

SAN Lumps are solid, irregularly shaped pieces of Styrene Acrylonitrile copolymer obtained from production off-cuts, purging, or rejected batches during the manufacturing process. SAN is a thermoplastic resin made from styrene and acrylonitrile, combining the clarity and rigidity of polystyrene with improved chemical resistance and higher heat tolerance from acrylonitrile.

These lumps are a high-quality recyclable raw material suitable for reprocessing into pellets, which can then be used for various injection molding and extrusion applications. SAN Lumps are valued in the plastics industry for their transparency, glossy surface, dimensional stability, and durability.

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:
• The material is carefully loaded into the container.
• During loading, we document the entire process with pictures and videos, capturing essential details such as:
• Material condition
• Loading procedure
• Container and seal numbers
• 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.

Material Composition:

• 100% Styrene Acrylonitrile (SAN)

• Composition: ~70–80% Styrene, ~20–30% Acrylonitrile (varies by grade)

• Origin: Post-industrial manufacturing purge or production waste

Physical Characteristics:

• Form: Solid irregular lumps

• Color: Natural/transparent, white, or tinted (depending on source)

• Density: ~1.07–1.10 g/cm³

• Moisture Content: Low

• Odor: Neutral (free from strong chemical odors)

Key Properties:

• High transparency and glossy finish

• Good impact strength (better than GPPS, lower than ABS)

• Excellent resistance to chemicals, oils, and alcohols

• Higher heat resistance than general polystyrene

• Low moisture absorption for stable processing

Applications After Recycling:
Recycled SAN from lumps can be used in:

• Cosmetic and toiletry containers

• Transparent storage boxes and kitchenware

• Office supplies (rulers, pen bodies, desk organizers)

• Appliance housings (mixers, blenders, fans)

• Automotive interior parts

• Lighting components and display covers

Advantages:

• High Recyclability: Can be reprocessed multiple times without significant loss of properties

• Cost-Effective Alternative: More affordable than virgin SAN while retaining quality

• Versatile Applications: Suitable for both transparent and colored molded products

• Chemical Resistance: Withstands detergents, oils, and alcohol-based products
