Key Players
Competitive Landscape
Four company groups compete here. Silicone makers form one group. Battery assembly suppliers form another. A third group focuses on heat control. Local technical teams form the fourth group. Silicone makers compete on gel flow and cure behavior. They also compete on electrical insulation. Battery suppliers sell gap fillers with adhesives or insulation. Heat-control firms focus on heat flow and gap size. They also help customers design products. Local teams support trials and gel application.
In 2025, more spending went to application tests. EV programs wanted faster approval of thermal materials. Dow introduced DOWSIL EG-4175 Silicone Gel in September 2025. It was for high-voltage EV power electronics. In 2026, Qnity expanded Laird heat-control work with automotive customers. Laird received recognition from BorgWarner in May. Companies must prove material performance on factory equipment. They must also prove stable use. A gel must do both without adding cell stress or rework.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| June 2026: 3M expanded its The Next Gear automotive platform with battery and thermal-management solution content. | Vehicle teams need material options that can be compared inside the same electrical and thermal design workflow. | Thermal management is moving closer to whole-vehicle design decisions instead of isolated material selection. | Suppliers can win earlier design engagement by linking thermal materials with adjacent electrical-insulation needs. |
| September 2025: Momentive’s Ohta plant received IATF 16949 certification for silicone electronic-material design and manufacturing. | Automotive programs require controlled design and manufacturing systems before approved materials reach serial production. | Quality-system evidence is becoming part of the thermal-material qualification package. | Certified production sites can support longer automotive programs that require repeatable process control. |
| November 2025: Shin-Etsu presented its SDP thermal-interface gap filler series at PLASTIC JAPAN. | Design teams need soft, conformable thermal interfaces for uneven electronics surfaces. | Higher-conductivity liquid gap fillers are expanding beyond traditional pad formats. | Application support can target power electronics and automotive units with large or irregular gaps. |
Parker LORD and DuPont offer products that help control battery heat. T-Global Technology focuses on gels. It also offers other interface products. These products serve electronics and vehicle programs.

Together, these firms sell materials in many countries. They also help with battery assembly. Their work covers heat-control contact layers. It also includes local technical help.
Who leads the battery thermal interface gels market?
Dow, Henkel, and Wacker Chemie offer broad silicone or thermal-interface ranges. They work with car customers in many regions. Parker LORD, DuPont, and 3M serve more focused battery and electronics needs. Specialist suppliers do the same. Public evidence does not name one market-share leader within the defined gel scope.
Which companies have documented qualification or quality approvals?
Momentive’s Ohta plant holds IATF 16949 certification. The certificate covers silicone materials for electronics. It covers design and production. Wacker Chemie says SEMICOSIL 9649 TC meets vehicle quality rules. It also meets product specs. Other suppliers publish records of approval or use for vehicle product families.
Which companies provide battery or automotive thermal gel products?
Henkel, Wacker Chemie, T-Global Technology, and Parker LORD offer thermal-interface products for vehicle use. The products can be applied on production lines. Shin-Etsu Chemical, DuPont, and Laird Technologies also offer gap fillers or gel-like thermal materials. These products serve batteries and power electronics.
Which companies serve North America and Europe?
Dow, Henkel, 3M, Wacker Chemie, Momentive, DuPont, and Laird Technologies work in North America and Europe. They provide sales or technical support. Parker LORD also supports customers in both regions. T-Global Technology serves the same markets through a smaller thermal-interface network.

Research Methodology
This section shows the main supplier types in the battery thermal interface gels market. A company appears only when current records show products that fit this scope. These products can be machine-applied gels or gap fillers. Closely related battery products may also fit the scope. The records must apply to batteries or vehicle electronics. Sources include vehicle quality records and company news. We also use technical documents and public filings. Each claim must apply to the named heat-control or battery-material product family. We do not apply that claim to the company’s wider portfolio. Market-share estimates remain proprietary FMI assessments for the 2026 to 2036 forecast period.
