Ortroftaalihartseilla

Ortroftaalihartseilla, often referred to as ortho-phthalic resins, is a common type of unsaturated polyester resin. These resins are synthesized through the reaction of phthalic anhydride and glycols, typically propylene glycol or ethylene glycol. They are characterized by their cost-effectiveness and ease of processing, making them a popular choice for a wide range of applications.

The curing process of ortroftaalihartseilla involves a chemical reaction, usually initiated by a catalyst, where the liquid resin transforms into a solid, rigid material. This process can be accelerated or modified by various additives. The cured ortroftaalihartseilla exhibits good mechanical properties, including strength and rigidity, as well as acceptable chemical resistance.

Key applications for ortroftaalihartseilla include the manufacturing of fiberglass reinforced plastics (FRP). These composite materials are found in numerous products such as boat hulls, automotive parts, construction materials, and storage tanks. Due to their versatility and economic advantages, ortroftaalihartseilla remain a staple in the composites industry. However, they generally offer lower performance characteristics compared to isophthalic or DCPD resins in terms of heat resistance and chemical durability.
