No, Bakelite is not an unsaturated polyester; it is a type of thermosetting plastic known as a phenolic resin. It is made by polymerizing phenol and formaldehyde, resulting in a hard, durable material. Unsaturated polyesters, on the other hand, involve a different chemical structure and are typically used in applications such as fiberglass and coatings.
Polyester resins can be skin sensitizers. In addition, unsaturated polyesters also contain styrene monomer. While this is not a proven carcinogen, breathing the vapors is not healthy.
Fibreglass resin is a polyester.
Reactivity tests in unsaturated polyester resin are conducted to evaluate the resin's curing behavior, stability, and performance under different conditions. These tests help determine the optimal conditions for polymerization, including temperature and catalyst concentration, ensuring effective cross-linking and final material properties. Additionally, they assess the resin's compatibility with various fillers and additives, which is crucial for achieving desired mechanical and thermal characteristics in the final product. Understanding reactivity also aids in predicting the shelf life and processing conditions necessary for the resin's application.

as polyester resin is a bi-product of oil so if the prices of oil rise then it is definite that the polyster resin price will also rise.
Once polyester resin cures (hardens) through a chemical reaction—usually with a catalyst like MEKP—it forms a rigid, cross-linked structure that cannot be melted or reshaped again. This irreversible curing process is the key characteristic of thermosetting materials. In contrast, thermoplastics soften when heated and can be remolded multiple times, which polyester resin cannot do after curing. That’s why polyester resin is widely used in fiberglass, boat hulls, automotive parts, and construction—applications where heat resistance and structural strength are essential.
