IRPC  and  its  subsidiaries  produce  polymer  products under the brand POLIMAXX. As downstream  petrochemical products, polymers are the feedstock for various plastic products. IRPC manufactures two groups of polymers. The polyolefins group comprises HDPE and PP, while the styrenics group includes ABS, PS, and EPS. Each polymer type possesses distinct properties and lends itself to different applications:


PP  is  widely  used  in  several  industries,  including  packaging, electronic appliances, automotive parts, and  medical-grade  equipment  and  apparatuses.  IRPC produces PP Homopolymer, impact-resistant  PP Block Copolymer, and extratransparent PP Random  Copolymer. It also manufactures PP Compounds, which allow additive and color customization according to the needs of each industrial client.


High Density Polyethylene (HDPE) IRPC’s HDPE is a high-density polyethylene product with in-line compounding. It is suitable for pipe extrusion, especially water supply pipes, electrical conduits, and drainage pipes. Moreover, IRPC has developed a special grade of HDPE for the production of solar farm pontoons, which require exceptional weather resistance.


IRPC produces two categories of PS based on its properties. General Purpose Polystyrene (GPPS) offers  transparency and hardness. It is easily molded but has low-impact strength and is thus commonly used to make products that require transparency and structural integrity,  such  as  refrigerator  shelves  and  other  household appliances. High Impact Polystyrene, on the other hand, can withstand more impact than GPPS, 

thanks to the addition of butadiene rubber. Both types of PS are compatible with injection molding and sheet extrusion.

Expandable Polystyrene

Expandable Polystyrene (EPS) 

IRPC mainly uses styrene monomer as feedstock for its EPS, with pentane as the blowing agent. The Company uses no ozone-depleting CFCs. EPS has the following uses:

  • Packaging, such as the shock absorbing material in electrical appliance packaging 
  • Blocks,  such  as  insulation  blocks  in  the  fishing  industry’s  cold  storage  rooms  and  modern  constructions  to  save  energy  consumption  in  cooling and reduce construction expenses. EPS Blocks can also be used in decorative works.

Acrylonitrile Butadiene Styrene

Acrylonitrile-Butadiene-Styrene (ABS)
IRPC produces many grades of ABS, each with its unique properties, such as high-impact and super high-impact  resistance,  high  gloss,  and  high  heat  resistance. Compatible with injection molding and sheet extrusion, ABS is commonly made into products that require durability, finesse, and shine, such as parts for electronic appliances, internal and external automotive parts, household appliances, sanitaryware,and children’s toys. This is because ABS is strong, durable,  and  resistant  to  heat  and  high  impact,  exhibits  good  paint  adhesion,  and  can  withstand  various chemicals and solvents, such as thinners. It also produces high gloss and can be made into many different vibrant colors or even plated with a metal.

Acrylonitrile Styrene (SAN)

Transparent, hard, strong, and tough, SAN (or AS) has higher thermal and chemical resistance than PS. It is commonly used to manufacture lenses for headlights and  taillights,  some  parts  of  turn-signal  lenses,  household appliances such as sanitaryware, lighters and containers, as well as electrical appliances such as fan blades and blenders. In addition to the properties previously  mentioned,  SAN  also  produces  glossy  surfaces, has high rigidity, and is particularly resistant to shear force.
