Block copolymers produced by copolymerization with ethylene are widely used as high-performance polypropylene polymers. The second stage of the polymerization follows the polymerization of the HOMO polymer to give the polymer the ethylene-propylene rubber component.
In particular, the polymerization process using the horizontal vapor phase method allows the rubber component to be uniformly dispersed in the resin matrix, enabling the achievement of high impact performance even with low rubber content, and a high rigidity-impact balance can be achieved.
The JPP Horizone™ Process is in high demand worldwide for industrial hard durability applications and as an indispensable polymer for automotive manufacturing.


This is a new type of TPO resin that takes full advantage of the JPP Horizone™ Process, which allows the maximum composition ratio of ethylene propylene rubber in the polymerization reactor to be up to 57%, and the ethylene/propylene composition ratio in the rubber to be easily and freely adjusted, This new type of TPO resin is manufactured by maximizing the characteristics of the JPP Horizone™ Process and can meet the difficult composition and property requirements of PP consumers.
This new type of TPO resin, named NEWCON, is manufactured by taking full advantage of the Horizon process and can meet the difficult composition and physical requirements of PP consumers.

  • High impact properties (room temperature and low temperature)
  • High compatibility with other resin materials (used as PP modifier)
  • IMPACT COPOLYMER with high transparency
  • Whitening resistance performance

In particular, it is widely used by automobile manufacturers and parts suppliers as the main raw material for compounding resin used in PP resin parts for automobiles, and is also being developed for new applications in industrial materials.


One of the major markets for polypropylene is stretchable film, which is widely used as a packaging material for food and household products. Among these a ternary polymer with a low melting point, is gaining popularity for heat-sealing applications in food packaging. It is highly regarded for its ability to seal bags at low temperatures, thereby minimizing temperature loss during processing and energy consumption.
JPP is also focusing on the development of production technology for this ternary polymer with ethylene butene as a comonomer, and this low-melting-point product line can also be produced on the JPP Horizone™ Process.
