70% of Dielectric Elastomers industry Dominated by TOP 3 Players

Dielectric elastomers consist of a highly stretchable elastomeric film (usually a silicone rubber elastomer, acrylic elastomer, or polyurethane elastomer) as a dielectric, flanked on both sides by highly flexible electrodes made of graphite or carbon black. coated.
Dielectric elastomers (DEs) are smart material systems that generate large strains. They belong to the group of electroactive polymers (EAP). A DE actuator (DEA) converts electrical energy into mechanical work. They are light and have a high elastic energy density. They have been studied since the late 1990s. There are many prototype applications.

Dielectric elastomers, consisting of a flexible polymer film sandwiched between top and bottom layers of flexible electrodes, were developed and developed in late 1991 by SRI International, a non-profit international research institute. Upon external electrical stimulation, dielectric elastomers can change shape or volume. When the external electrical stimulus is removed, dielectric elastomers can restore their original shape or volume, resulting in stress and stress converting electrical energy into mechanical energy.

Dielectric elastomers feature large electrical strain, high energy density, fast response, low viscoelastic hysteresis loss (mechanical loss), and high conversion efficiency. It is mainly used to manufacture light weight, small size and high precision actuators. Possibilities of intelligent materials. The principle of dielectric elastomer actuators was first proposed in 1880 by Wilhelm Conrad Rntgn. When a voltage is applied to two electrodes, an electric charge is generated between the two electrodes and an electrostatic attraction is generated in the thickness direction of the elastic membrane. In the horizontal direction, electrostatic repulsion of homopolar charges stretches the film on the single-sided electrode, resulting in changes in thickness and area. The thickness is reduced and the area is expanded.

Currently, the world’s leading dielectric elastomers companies include 3M, Dow, Altropol, Nusil and BJB, of which 3M is the world’s largest dielectric elastomer manufacturer with a revenue share of 34.93% in 2020. Dow and Altropol follow in second and third place. The top three players own approximately 75% of the world’s stock. The industry is very concentrated. There are companies looking for cost and quality leadership that will build new capabilities and improve profitability. At the same time, companies focus on innovation, equipment upgrades, and process improvements to reduce costs and improve quality. The global dielectric elastomer market is projected to reach USD 39.2 million from USD 23.16 million in 2020-2026, growing at a CAGR of 9.71% during 2021-2027. North America accounted for the largest revenue share in the dielectric elastomer market in 2020. This region is characterized by the presence of a large number of service providers, especially in the United States. At the same time, Asia-Pacific is expected to grow at the highest CAGR during the forecast period.
