Despite its numerous advantages, polycarbonate has limitations that bulk buyers should consider for optimal selection:
Higher Production Cost:
Compared to polymers like polyethylene or polypropylene, polycarbonate is more expensive, which can be challenging for budget-constrained projects due to specialized raw materials and complex production processes.
Scratch Sensitivity:
Polycarbonate surfaces are prone to scratching, especially in applications like lenses or transparent sheets. Protective coatings like silicone layers can mitigate this but add extra costs.
Limited Chemical Resistance:
Polycarbonate is sensitive to solvents like acetone, benzene, and aromatic hydrocarbons, which may cause swelling, cracking, or degradation, limiting its use in harsh chemical environments like laboratories or chemical plants.
Moderate Thermal Stability:
Softens or deforms at temperatures above 120–130°C, restricting its use in high-heat environments like components near hot engines. Heat-resistant additives can partially address this.
UV Degradation Without Additives:
Without UV stabilizers, polycarbonate yellows and becomes brittle under sunlight, limiting outdoor applications without protection. UV stabilizers are essential for long-term quality.
Complex Recycling:
While recyclable, polycarbonate’s recycling process is more challenging than simpler polymers like polyethylene due to its complex structure and additives, posing challenges for sustainability-focused projects.
Static Electricity:
Polycarbonate is prone to static electricity, attracting dust in sensitive applications like electronics, requiring anti-static measures or coatings.

Proper storage is essential to maintain polycarbonate’s quality and prevent degradation. Improper conditions can affect performance or physical properties. Key requirements include:
Avoid Heat and Flames:
Polycarbonate is flammable and must be stored away from heat sources, open flames, and high temperatures (above 50°C). Warehouses should have adequate ventilation to prevent vapor buildup.
Prevent Chemical Exposure:
Contact with solvents like acetone, gasoline, benzene, or strong acids can cause degradation or discoloration. Store products in chemical-free environments using protective containers like plastic pallets.
Protect from Direct Sunlight:
UV light can cause yellowing and reduced clarity. Store in shaded warehouses or with UV-protective coverings to preserve quality.
Prevent Pressure and Scratches:
Polycarbonate sheets and parts are scratch-sensitive and should not be subjected to heavy pressure or sharp objects. Use protective layers like plastic films or foam during storage to prevent surface damage.
Control Humidity:
While polycarbonate is generally moisture-resistant, prolonged exposure to high humidity (above 60%) can degrade surface quality or affect additives. Store in dry, well-ventilated warehouses.
Proper Stacking:
Polycarbonate sheets should be stored horizontally on flat pallets to prevent bending or cracking. Use soft separators between sheets to reduce friction.
Accurate Labeling:
Products should be labeled with details on grade, weight, and storage conditions to prevent handling errors.
Proper packaging and transport are critical to maintaining polycarbonate’s quality throughout the supply chain. Key requirements include:
Robust Packaging: Polycarbonate should be packaged with resistant materials like plastic films or foam to prevent scratches and impacts. Large sheets should be secured on sturdy, flat pallets to avoid bending.
Hazard Labeling:
Packages should carry warning labels about flammability, chemical sensitivity, and UV protection needs to ensure workers and transporters are aware of risks.
Prevent Friction: Excessive friction during transport can generate static electricity and damage polycarbonate surfaces. Use anti-static materials or specialized packaging to minimize this risk.
Weather Protection:
Protect polycarbonate from rain, snow, and humidity, especially during open-air transport. Use waterproof coverings and sealed containers.
Compliance with Transport Standards:
Depending on volume and type, adhere to international chemical transport standards like ISO 14001 or IMDG to ensure supply chain safety.
Temperature Monitoring:
Transport vehicles should have temperature control systems to prevent excessive heat (above 50°C), which can cause material deformation.
Transport Insurance:
For large shipments, transport insurance is recommended to cover potential damages from unforeseen incidents.
Polycarbonate production is a precise process that may encounter challenges. Identifying and addressing these ensures high-quality output. Common issues include:
Melt Viscosity Variations:
Inconsistent viscosity can disrupt processes like extrusion or injection molding, often due to variations in bisphenol A quality or incorrect equipment settings. Pre-production viscosity testing and precise temperature/pressure control (typically 250–300°C) mitigate this.
Raw Material or Additive Contamination:
Impurities like dust or chemical residues can reduce clarity or mechanical properties. Advanced filtration systems and regular equipment cleaning minimize this issue.
Surface Defects or Bubbles:
Caused by high moisture in raw materials or improper polymerization temperatures. Drying materials at 120°C for 4 hours and controlling reactor temperatures (250–300°C) resolve this.
Thermal Degradation:
Excessive temperatures can break polymer chains, reducing strength. High-quality antioxidants and precise temperature control manage this issue.
Premature Yellowing:
Occurs without adequate UV stabilizers during production or use. High-quality UV additives and ASTM G154 testing prevent this.
Color Inconsistency in Tinted Grades:
Uneven pigment distribution can lead to non-uniform appearance in colored polycarbonate. Advanced mixers and precise blending processes reduce this issue.
Internal Stress Formation:
Rapid or improper cooling can cause internal stresses, leading to cracking or deformation over time. Gradual cooling and optimized mold settings address this.
Selecting high-quality polycarbonate is critical for durable, efficient products. Bulk buyers should consider:
Raw Material Quality:
Polycarbonate should be produced from high-purity bisphenol A to ensure consistent mechanical and optical properties. Verify certifications like ISO 9001 and raw material test reports.
Melt Volume Rate (MVR):
MVR should align with production processes (e.g., extrusion or injection molding), typically 5–30 cm³/10 min. Request MVR data from suppliers for optimal performance.
UV and Fire Resistance:
For outdoor or high-risk applications, ensure polycarbonate contains UV stabilizers or flame retardants. Check standards like ASTM G154 for UV and UL 94 for fire resistance.
Standards Compliance:
For medical or food-related applications, ensure compliance with FDA or ISO 10993 standards. Verify the absence of harmful contaminants like free BPA in sensitive grades.
Grade Variety:
Suppliers should offer diverse grades (transparent, reinforced, flame-retardant, etc.) to meet specific project needs.
Technical Support and After-Sales Service:
Reputable suppliers should provide technical consultation for grade selection, process optimization, and issue resolution. Access to technical support teams is a major advantage for bulk buyers.
Product Traceability:
Suppliers should provide detailed information on material origin, production processes, and quality tests to ensure product traceability in the supply chain.
Pre-Purchase Sampling and Testing:
For large projects, request small samples for production line testing to ensure material compatibility with project requirements.
