Polypropylene (PP) is semi-crystalline polymer used in many industrial applications including automotive industry as a result of its physical, thermal and chemical properties namely low density, high melting point, stiffness, good impact properties, chemical inertness, good clarity, excellent barrier properties and low cost.

The versatility and economy of polypropylene creates opportunities for cost-effective and innovative design. ACI, have been developed several grades of PP compounds with diverse performance characteristics for production of cables and wires for the automotive sector. Polypropylene compounds are designed to accomplish with temperature class C (- 40 to 125 °C).

The demand for highly flexible Halogen Free Flame Retardant (HFFR) cables in automotive sector has been increasing and it is being enforced due to the environmental, health and safety concerns with the basic raw materials used in manufacturing of insulation wire.

These concerns, include brominated flame-retardants, are driving innovation and change in the industry. These compounds were developed with the purpose of replace PVC based compounds. ACI have been developed flexible HFFR compounds. In order to achieve flame retardance requires, polyolefins formulations need high levels of additives. However, the additives tend to negatively impact the mechanical properties of the compound. The combination of a smart manipulation of additives and the right polymer technology, have allowed the development of high quality HFFR.

ACI portfolio also have available compounds lightly halogenated (percentage of halogenated < 12%). Brominated compounds are more effective and at moderate loadings they reduce the flammability of polypropylene products. Therefore, these compounds are suitable to meet strict flammability performance requirements.

ACI, also provide a TPE (Thermoplastic elastomer) material which can be used in wire and cable jacketing and insulation. TPE is a combination of a plastic and rubber material thus have the properties of elastomers but can be processed in the same ways as thermoplastic. As elastomers, TPEs exhibit high elasticity.
