The Effect of Benzoyl Peroxide Concentration on Thermal Polypropylene Degradation

Introduction

Polypropylene (PP) is a widely used plastic material in various industrial applications due to its excellent physical and mechanical properties. However, the thermal degradation of polypropylene is a significant concern that can affect its performance and durability. Benzoyl peroxide (BPO) is a common decomposing agent used to facilitate the breakdown of polymer chains, leading to changes in the nature of polypropylene. This study aims to analyze the effect of benzoyl peroxide concentrations on thermal degradation of polypropylene, with a focus on understanding the influence of BPO on the physical and structural properties of degraded PP.

Background

Polypropylene is a thermoplastic polymer that is widely used in various applications, including packaging, automotive, and construction materials. However, the thermal degradation of polypropylene can lead to a decrease in its physical and mechanical properties, making it less suitable for certain applications. Benzoyl peroxide is a common decomposing agent used to facilitate the breakdown of polymer chains, leading to changes in the nature of polypropylene. The concentration of benzoyl peroxide used can significantly affect the thermal degradation process, and understanding its influence is crucial for designing better and more efficient polypropylene materials.

Methodology

In this study, variations in the comparison of the weight of polypropylene (PP) and benzoyl peroxide (BPO) used were (95%: 5%), (90%: 10%), (85%: 15%), (80%: 20%), and (75%: 25%). The polypropylene then undergoes a thermal degradation process by adding various benzoyl peroxide concentrations. Characterization is done by measuring intrinsic viscosity, determining the molecular weight, and melting point. Further analysis was performed using the Differential Thermal Analysis (DTA) and Fourier Transform Infrared Spectroscopy (FTIR) to evaluate changes in structures that occur in polypropylene.

Results

The result of characterization shows that the higher the added concentration of benzoyl peroxide, the lower the intrinsic viscosity value, molecular weight, and the melting point of the polypropylene produced. This indicates that the thermal degradation of polypropylene is significantly influenced by the addition of benzoyl peroxide. This process leads to the cutting of the polymer chain, which is reflected in the results of the FTIR test which shows a change in structure in polypropylene.

Discussion

Thermal degradation of polypropylene is very important to understand because polypropylene is one type of plastic that is widely used in various applications. This degradation process can affect the physical and mechanical properties of the material used in the industry. Benzoil peroxide as a decomposing agent functions to facilitate the breakdown of polymer chains that cause changes in the nature of polypropylene.

Various concentrations of benzoil peroxide provide insight about how the right dose can affect the final outcome of thermal degradation. In this case, the use of higher benzoil peroxide does not always mean better results. Decreased viscosity and molecular weight shows that the material can be more fragile, which may not be desirable for certain applications.

From the results of DTA and FTIR's analysis, we can understand more about the thermal and structural properties of degraded polypropylene. DTA provides an overview of the energy changes that occur during heating, while FTIR provides information about chemical bonds that are formed or cut off, providing a deeper insight about the mechanism of degradation.

Conclusion

Thus, this study made a significant contribution to the development and use of polypropylene in industrial applications. A better understanding of the influence of benzoil peroxide on thermal degradation can help in designing better and more efficient polypropylene materials, both for products that are more environmentally friendly and to improve material performance in diverse applications.

Based on the findings of this study, the following recommendations can be made:

  • The use of benzoyl peroxide as a decomposing agent should be carefully controlled to avoid excessive degradation of polypropylene.
  • The concentration of benzoyl peroxide used should be optimized to achieve the desired physical and mechanical properties of polypropylene.

This study has several limitations that should be acknowledged:

  • The study was conducted using a limited number of benzoyl peroxide concentrations, which may not be representative of all possible concentrations.
  • The study focused on the thermal degradation of polypropylene, and further research is needed to understand the influence of benzoyl peroxide on its physical and structural properties.
  • The study did not investigate the environmental impact of benzoyl peroxide on polypropylene degradation.
