Frequently Asked Questions (FAQ):
What is the main difference between Makrolon 2805 and other PC grades?
Makrolon 2805 is a general-purpose grade optimized for injection molding, offering a balanced set of properties (mechanical, thermal, processing) without specializing in extreme high heat or ultra-high impact. It is a versatile starting point for many applications.Is Makrolon PC 2805 suitable for outdoor applications?
Polycarbonate has good UV resistance, but for long-term outdoor use, UV-stabilized grades are recommended. Makrolon 2805 can be used outdoors if the specific requirements (like color fade, weathering) are evaluated.What are the typical injection molding parameters for this resin?
General parameters include a melt temperature range of 280-320°C and mold temperatures of 80-100°C. Specific settings depend on part design and machine. We provide processing guidelines upon request.Can this material be colored or mixed with additives?
Yes, Makrolon 2805 can be compounded with colorants, lubricants, or other additives. Masterbatch coloring is common. Custom formulations can be discussed.Is it compatible with food contact or medical applications?
The base polymer may have potential, but compliance requires specific certifications and formulations. For regulated applications, please inquire about specialized grades and necessary documentation.What is the shelf life or storage condition for this resin?
Polycarbonate should be stored in a dry, cool place away from direct sunlight. Properly stored, it has a long shelf life. We recommend using it within standard industry timelines.Do you provide material samples for testing?
Yes, sample quantities are available upon request for customer evaluation and trial molding runs.How can I verify the authenticity of the Covestro material?
We supply material with original packaging and documentation. Certificates of analysis and batch information can be provided to ensure traceability and quality.
