Poetry resin PP (SP179) is mainly used for production of car bumper. SP179 is a kind of anti -rushing co -polyetrythylene resin with excellent impact resistance and processing performance, which can meet the strength and durability requirements of the car bumper. By controlling parameters such as the residence time of the average cluster in the ring tube, equal index, melt flow rate, and ethylene content, qualified SP179 products can be produced.

Production process
The production process of SP179 mainly includes the following steps:

‌1.Selection of catalysts: industrialized production is used with Zn118 catalyst.
2.Reaction condition control: By controlling the residence time of the average cluster in the ring tube, the regulatory index, the melt flow rate, and the ethylene content, ensure the quality of the product.

Performance characteristics
SP179, as a embedded cluster, has the following characteristics:

1.Low the content of non -sequences: This helps improve the mechanical performance and processing performance of materials.
2.Anti -impact performance excellent components suitable for high impact strengths such as car bumper and other components.
3.Good processing performance: Through scanning electron microscopy (SEM), transmitting electron microscope (TEM), differential thermal analysis (DSC), nuclear magnetic resonance (NMR), gel penetration chromatography (GPC) and other analysis techniques, the processing performance is verified.

Application field
SP179 is mainly used in the production of car bumpers.

Because of its excellent impact resistance and processing performance, it can meet the strength and durability requirements of the car bumper.

In addition, the SP179 has the following application prospects:

1‌.Car parts: In addition to the bumper, it can also be used for other car parts that require high impact strength.
2.Other industrial applications: Due to its good processing and mechanical properties, SP179 may also find applications in other industrial fields.

To sum up, the SP179 performed well in the production of the car bumper and has a wide range of application prospects.
