COMPOPP - PP Compounds - Reinforced with talc and/or fiberglass

COMPOPP is the designation of polypropylene (PP) homopolymer or copolymer reinforced with talc and/or fiberglass. If necessary, these products can have flame retardant properties to meet UL-94 standards.




Reinforced PP compounds can have between 10% and 50% of fiberglass content. These compounds are used in the plastics industry with the aim of enhancing the mechanical properties.


Some advantages of fiberglass compounds are:


• Ease of molding parts with complex shapes;

• Lighter than steel although stronger and with identical mechanical and thermal properties;

• High tensile, impact, compression, flexion under load, tear strength and abrasion properties;

• Chemical resistance;


Application of fiberglass reinforced PP:


• Extrusion (Pipes);

• Injection (technical parts, automotive and household electrical appliances).




Compounds of talc reinforced PP may contain between 10 and 40% of talc.


The addition of talc has several advantages, including:


• Stiffness (E-Modulus), Resistance: impact, thermal conductivity and thermal deflection;

• Nucleating Properties;

• Chemical resistance;

• Reduced water absorption and mould shrinkage.


Application of Talc reinforced PP


• Injection (technical parts, automotive and household electrical appliances).
