Oil and gas pipelines play a vital role in today’s energy industry, serving as the backbone of energy delivery and supply chains. However, the long-term use of these pipes is exposed to various environmental conditions and chemicals, making them susceptible to corrosion and damage. Corrosion protection is therefore critical to maintaining the integrity of pipelines. In recent years, innovations in tritium-unsaturated polyester resin technology have provided sustainable, efficient and environmentally friendly solutions to enhance the anti-corrosion work of oil and natural gas pipelines.

In modern medical device manufacturing, material selection is critical. These devices need to meet high standards of hygiene while possessing excellent mechanical properties and durability. unsaturated polyester resin have emerged as one of the ideal materials for manufacturing medical devices. This article will explore the widespread use of unsaturated polyester resin in medical device manufacturing and the benefits it brings.

Composites have always played an important role in engineering, providing outstanding strength, lightweight and versatility. Unsaturated polyester resins, as one of the key components of composite materials, have emerged in this field in recent years.

Unsaturated polyester resin（UPR）, is a type of polymer formed through the polycondensation reaction between polyacids and polyalcohols. This process produces water as a by-product. Unsaturated polyester resin（UPR）is a versatile, easily moldable liquid polymer that, when cured (cross-linked with styrene using specific substances like organic peroxides, known as hardeners), retains the solid shape it takes in the mold. The resulting products exhibit exceptional strength and durability characteristics.
