How Additives Improve PC Properties？
PC can be modified to enhance its properties by adding additives, following are some common types:
- Flame retardant additives can improve the fire resistance of PC.
- UV stabilizers can be added to enhance PC’s resistance to degradation caused by exposure to ultraviolet radiation.
Blending PC with other polymers can mix their strengths and minimize their weaknesses, for instance:
- PC/ABS Blends: enhance impact resistance and improve processability, making it suitable for applications requiring toughness and rigidity, such as automotive interior parts and consumer electronics housings.
- PC/PMMA Blends: enhance optical clarity and weatherability, making it suitable for applications such as automotive lighting lenses and outdoor signage.

Is PC safe for use?
Yes, PC material is generally considered safe for use in various applications. However, like any material, PC may release small amounts of bisphenol A (BPA) under certain conditions, which has raised some concerns about its safety. To address this, manufacturers often produce BPA-free PC products or use alternative materials for specific applications where BPA exposure is a concern.
Is PC material recyclable?
Yes, PC material is recyclable, but the recycling process can be more challenging compared to other plastics due to its high melting point and complex chemical composition.
What is general tolerance for PC injection molding parts?
The general tolerance for PC injection molding parts typically ranges from +/- 0.05 mm to +/- 0.1 mm, depending on factors such as part geometry, size, and specific requirements of the application.
