# Top 50 chemical companies in Michigan

Tamtam tracks 58 chemical companies headquartered in Michigan. This list ranks the 50 largest by number of employees on LinkedIn, led by Masco Corporation, Cooper Standard and Guardian Industries. Their median headcount is 332. Half of them were founded in 1973 or later. The most common headquarters are Grand Rapids (3), Auburn Hills (2) and Dearborn (2).

The chemical companies in Michigan include large manufacturers of plastics, glass, and automotive components. Among them are Masco Corporation, a global leader in home improvement products, and Cooper Standard, a supplier of sealing and fluid handling systems. Guardian Industries manufactures high-performance glass products, while Plastipak specializes in rigid plastic containers. Dow Performance Silicones offers silicon-based technology solutions, and Gentex Corporation focuses on electronics for automotive and aerospace.

These companies primarily operate in manufacturing, with a strong emphasis on materials science and engineering. Many are established firms, with several founded in the mid-20th century, such as Cooper Standard (1960) and Plastipak (1967). A notable pattern is the concentration of headquarters in southeastern Michigan, particularly around Detroit, with cities like Livonia, Northville, Auburn Hills, and Plymouth hosting major operations.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
