Impregnating Resins Market: Overview

Impregnating resins are liquids that are organic and slightly viscous. The resins generally contain formaldehyde, a naturally occurring compound, and are composed of trimers or dimers of the main molecule. However, they can turn into polymers by the act of curing, a chemical process involving the hardening or toughening of a given polymer. Impregnating resins are also called secondary insulators, and have the capability of curing the material to which they are applied.

Some of the main reasons why chemically enhanced liquid resins are gaining popularity is because they impart qualities like protection from climate changes, higher mechanical stability, and electrical insulation, along with better heat dissipation in copper coils or windings. They have wide applications in industrial units dealing with electrical motors, generators, and transformers along with other heavy metal industries.

Impregnating Resins Market: Growth Drivers

Rising demand in the automotive sector to propel market growth

The global impregnating resins market is projected to grow owing to the increasing demand for protection-providing resins in the growing automotive sector. Impregnating resins provide excellent cover against the changing environmental factors thus improving the overall shelf-life of the product to which they are applied. Consumers of automotive sectors are demanding vehicles that can withstand environmental changes since vehicles are extremely prone to damage in case of sudden climatic conversions since the quality of insulation provided to the motor determines its efficiency and durability.

Resin impregnation is becoming more popular in the production of electric vehicles (EVs). The increasing demand for durable engines that also have qualities like lower noise emission and better power density, is on the rise. The market for EVs has been expanding owing to various factors like increased income, environmental impact awareness, and others. In the United States, around 607,659 units of EVs were sold in 2021 with a total sales revenue of 2.31 million

Impregnating Resins Market: Restraints

Low efficiency of solvent-based resins to restrict market expansion

The global market size may witness restricted growth owing to the poor performance of solvent-based impregnating resins since they offer poor heat resistance as compared to its counterpart. There are also concerns about the reaction of solvent-based resins with the external environment resulting in diminished performance quality.

Impregnating Resins Market: Opportunities

Growing demand for EV’s in emerging economies to provide excellent opportunities

The global impregnating resins market size is projected to benefit from the rising demand for electric vehicles in developing economies, where there is significant growth in the modernization of regions resulting in an improved standard of living and higher disposable income. There is a growing trend of international players entering the newer regions since they have massive growth potential. With collaborations with domestic players or through heavy investments, more industry giants are anticipated to enter the EV industry in emerging economies.

Impregnating Resins Market: Challenges

Increased total costs pose a challenge to market growth

Using impregnating resins leads to an overall increase in the final cost of production and eventually the product. There are growing measures toward adopting other most cost-effective ways of providing the same insulation as impregnating resins however at lower prices. Such trends may lead to challenges for global market growth.

Impregnating Resins Market: Segmentation

The global impregnating resin market is segmented based on type, application, resin type, and region.

Based on type, the global market segments are solvent-based and solventless. The global market is projected to be dominated by the solventless segment during the projection period owing to the better output presented by solvent-free resins. Since they are less viscous, they provide deeper and faster impregnation in rotational parts or machines. Other factors like versatile processability, high reactivity, and better stability are some of the reasons for a higher adoption rate. Generally, more viscous resins have 2-6 epoxy groups for every molecule.

Based on application, the global market is divided into home appliances, motors & generators, transformers, power tools & electric tools, automotive components, and others where automotive components generate the highest revenue. The vehicle industry witnessed a growth of around 2.9% in 2021 from 2020 owing to the increased number of options in the vehicle segment catering to each consumer unit.

Based on resin type, the global market is divided into epoxy, polyester / unsaturated polyesters, polyesteramides, silicone, and others. The global market may witness high growth in the silicone segment since these resins offer resistance to extremely high temperatures as well as harsh chemicals that are extremely common in today's urbanized world. Silicones have an operating temperature ranging between -60°C and up to +230°C

Recent Developments:

• In March 2019, Hexion, a Columbus-based chemical company, announced the launch of a new epoxy solution designed for composite production in space. The epoxy solution is termed a one-of-its-kind and is made of two components, which is projected to relieve constraints related to the production of aerospace composites without impacting the high performance of the final parts.
• In April 2020, Hexion launched a new yellowing epoxy solution along with a unique curing agent. The epoxy solution will provide concrete protection while the amine curing agent is expected to help manufacturers meet the regulations regarding lower indoor air emissions along with the reduction in costs.
