Polypropylene compound (PP compound) is a composite material obtained by mixing polypropylene with various additives, fillers, reinforcements, and other polymers to enhance its properties and adapt it to specific applications. These additives can include glass fibers, talc, calcium carbonate, UV stabilizers, flame retardants, colorants, and plasticizers.

Technical Properties

• Density: 0.90 – 1.20 g/cm³ (depending on the type and amount of additives)
• Melt Flow Index (MFI): 2 – 50 g/10 min (at 230°C/2.16 kg)
• Melting Temperature: 160 – 170°C
• Glass Transition Temperature (Tg): -20°C (variable)
