An investigation of the electrical, mechanical and thermal properties of petroleum-based and bio-based polypropylene
An investigation of the electrical, mechanical and thermal properties of petroleum-based and bio-based polypropylene
Growing environmental concerns have accelerated the adoption of sustainable materials across the plastic manufacturing sector. Polypropylene (PP) is a prevalent material in plastics due to its versatile properties and practical applications. Yet, the production of traditional PP requires the depletion of fossil fuel. This investigation compares the properties of a bio-derived chemically identical PP (Bio-PP), and a traditional petroleum-based PP (iPP). Three sample groups were manufactured, including iPP, Bio-PP and a 50:50 mixture of the two materials. Samples were studied by chemical, mechanical, thermal, and electrical characterization. The results show no significant difference in melting temperatures and an increase in crystallisation temperatures with the addition of Bio-PP as well as a decrease in the Young’s Modulus. iPP shows relatively lower dielectric permittivity and higher DC breakdown than its bio-based counterpart. These behavioral differences are likely to be due to the contrast in average molecular weight as well as bio-based effects.

Abstract
Growing environmental concerns have accelerated the adoption of sustainable materials across the plastic manufacturing sector. Polypropylene (PP) is a prevalent material in plastics due to its versatile properties and practical applications. Yet, the production of traditional PP requires the depletion of fossil fuel. This investigation compares the properties of a bio-derived chemically identical PP (Bio-PP), and a traditional petroleum-based PP (iPP). Three sample groups were manufactured, including iPP, Bio-PP and a 50:50 mixture of the two materials. Samples were studied by chemical, mechanical, thermal, and electrical characterization. The results show no significant difference in melting temperatures and an increase in crystallisation temperatures with the addition of Bio-PP as well as a decrease in the Young’s Modulus. iPP shows relatively lower dielectric permittivity and higher DC breakdown than its bio-based counterpart. These behavioral differences are likely to be due to the contrast in average molecular weight as well as bio-based effects.
