Additives

• Heat stabilizer inhibit degradation during thermal processing
• Blowing agents are used to create expanded plastic foams
• Slip agents reduce frictional properties and allows films to slide smoothly
• Lubricants improve the flow and processing properties
• UV stabilizers are used for UV-sensitive plastics
• Nucleating agents encourage the formation of crystallinity
• Antiblock agents prevent film layers in rolls from sticking together
• Cross-linking agents impart cross links in the polymer chain
• Antistatic agents enable materials to dissipate static electrical charges
• Pigments are added to impart color
• Antioxidants protects the resin from deteriorating during thermal processing
• Mineral fillers improves mechanical properties
