Polypropylene Compound (PP Compound) – Engineered Performance from Iranian Private Manufacturers

Polypropylene Compound (PP Compound) is a modified form of polypropylene resin developed to achieve specific mechanical, thermal, and processing properties required in modern manufacturing. Unlike virgin PP, which is directly produced by petrochemical complexes, polypropylene compounds are created by private industrial manufacturers who enhance the base resin through the addition of various functional additives.

In Iran, virgin polypropylene is produced by major petrochemical companies such as Shazand, Jam, and Marun, all recognized for their high-quality on-grade PP granules. These virgin resins are then purchased by private compounding factories that blend them with materials like calcium carbonate, antioxidants, UV stabilizers, and color masterbatches to create PP compounds tailored for a wide range of industrial uses.

At Call2Supply, we supply Iranian PP compounds made by trusted private manufacturers who utilize on-grade PP from national petrochemical sources. Our product portfolio includes general-purpose and high-performance compounds suitable for automotive parts, household goods, pipes, film production, and industrial components. Each batch is processed with strict quality control to ensure consistent physical properties, uniform color, and reliable melt flow index.

What Makes Polypropylene Compound Different

The key advantage of PP compound lies in its customized formulation. By combining polypropylene resin with performance-enhancing additives, manufacturers can fine-tune the polymer’s density, flexibility, stiffness, and heat resistance. The most common additives include:

• Calcium Carbonate (CaCO₃): Added in varying percentages (from 5% to 40%) to increase rigidity, improve surface finish, and reduce production costs. It also enhances dimensional stability and reduces shrinkage during molding.

• Antioxidants: Protect the polymer during melt processing and extend the lifespan of the final product.

• UV Stabilizers: Prevent degradation caused by sunlight exposure, especially for outdoor applications.

• Impact Modifiers: Improve toughness and shock resistance, particularly for automotive and mechanical components.

• Color Masterbatch: Ensures consistent coloration for aesthetic and branding requirements.

Each compounding line uses twin-screw extruders equipped with precise temperature and torque controls to achieve homogeneous dispersion of additives within the polymer matrix. The final granules are cooled, pelletized, and packaged in 25 kg bags ready for export or local distribution.

Applications of PP Compound

Polypropylene compounds are used across diverse industries where a balance between lightweight design, chemical resistance, and mechanical strength is required.
Some of the main application sectors include:

• Automotive Manufacturing: For production of bumpers, dashboards, trims, and under-hood components that require high stiffness and dimensional stability.

• Household Goods & Appliances: Used in products such as chairs, containers, and appliance housings that demand strength, durability, and color consistency.

• Pipes & Fittings: Calcium carbonate–filled PP compounds are used for non-pressure pipes, drainage systems, and sheets.

• Textile & Fiber Industry: PP compounds are processed into fibers and nonwoven fabrics for packaging and industrial use.

• Packaging & Film: Suitable for injection molding and extrusion applications requiring balanced flexibility and transparency.

By using locally compounded polypropylene, manufacturers gain both cost efficiency and process flexibility, while maintaining performance standards comparable to imported grades.

Quality and Customization

All PP compounds offered by Call2Supply are produced by Iranian compounding plants that operate under ISO-certified quality management systems. Each batch undergoes melt flow index (MFI), density, and mechanical property testing to guarantee uniform performance.

Our supply network offers flexibility in:

• Additive type and loading percentage (e.g., 10%, 20%, 30% CaCO₃)

• Color customization based on client specifications

• Granule size and packaging options

• Melt flow rate adjustment for injection, extrusion, or blow molding applications

For international buyers, shipments are arranged through FOB Iranian ports, CFR, or CIF delivery terms. Optional third-party inspection by SGS, Bureau Veritas, or local inspection agencies can be organized before dispatch.
