Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a medium viscosity grade like PC-1100 for injection molding?
A: Medium viscosity offers an excellent balance. It flows easily enough to fill complex and thin-walled molds completely, reducing short shots, while being viscous enough to provide good melt strength, which helps in demolding and reduces warpage or sink marks.
Q2: Is the Lotte HOPELEX PC-1100 suitable for food contact applications?
A: The standard PC-1100 grade is a general-purpose transparent resin. For food contact applications, specific food-grade compliant grades are required. Please inquire with us for availability of food-contact approved versions or relevant documentation.
Q3: What are the recommended drying conditions before processing this PC resin?
A: Polycarbonate is hygroscopic and must be thoroughly dried. Typical recommendations are drying at 120°C for 3-4 hours in a dehumidifying hopper dryer to achieve a moisture content below 0.02%. Improper drying can lead to surface defects and reduced mechanical properties.
Q4: Can this resin be colored or tinted?
A: Yes, the natural transparent granules of PC-1100 are highly suitable for coloring. You can use masterbatches or liquid colorants compatible with polycarbonate to achieve a wide range of transparent, translucent, or opaque colors.
Q5: What types of molds work best with this material?
A> It performs well in standard hardened steel molds. For the best clarity and surface finish, highly polished mold surfaces are recommended. Adequate cooling and venting are also important to achieve optimal cycle times and part quality.
Q6: How does PC-1100 compare to other transparent plastics like PMMA (Acrylic) or PS?
A: PC-1100 offers significantly higher impact strength and toughness compared to PMMA and PS, making it suitable for applications requiring durability. It has a lower heat deflection temperature than PMMA but offers better overall mechanical performance. Its clarity is very good, though specialized optical-grade PMMA may have slightly higher light transmission.
Q7: Is it resistant to chemicals and UV light?
A: Polycarbonate has fair resistance to many dilute acids and oils but can be attacked by strong bases, aromatic hydrocarbons, and certain solvents. The standard PC-1100 has limited inherent UV resistance; for outdoor applications, a UV-stabilized grade is recommended.
Q8: What is the typical packaging and lead time for this product?
A: The resin is typically packaged in 25 kg paper bags with inner plastic lining. Lead times can vary based on order quantity and location. We maintain stock in Shanghai to ensure prompt delivery for standard orders.
