On November 29, 1941, Alabama native Sylvester S. Caldwell founded The Caldwell Company in Akron, OH. The company started as a manufacturer’s representative with Thompson Weinman & Co., a manufacturer in the rubber industry, as the first and principal client.

In 1959 the first manufacturing plant was opened on Home Ave. in Akron, OH. By the end of 1964, Americhem was manufacturing colour concentrates for ABS, many of which were used for the RV industry. In July 1965, Americhem Headquarters was moved to a new building in Cuyahoga Falls, Ohio. There was also an expansion with manufacturing in 1969 when a new plant was purchased in Medina, OH. Also in 1969, Americhem designed and manufactured the first masterbatches for vinyl siding.

In 1978, Americhem reached a milestone when opening their first research department. The new laboratory led to the production of Americhem’s first color concentrates for synthetic fibers in response to the new developments of nylon and polyester dispersion technology.

2009 saw a push for more eco-friendly practices. All plants and offices started participating in recycling programs and all plants switched from using carbon dioxide to liquid nitrogen as a coolant. The seventh Americhem plant was opened in 2010 in Liberty, NC with a specialty of black, white and additive masterbatch products. In 2011, Americhem Inc. celebrated their 70-year anniversary.

On December 28, 2012 Americhem Inc. purchased Infinity Compounding in Swedesboro, NJ later changing their name to Americhem Infinity Engineered Compounds

In December 2014, LTL Color Compounders was purchased.This precolor compound maker was merged with Americhem Infinity to form Infinity LTL Engineered Compounds.

In March of 2016, Americhem acquired Vi-Chem Corporation of Grand Rapids, MI, a producer of PVC and elastomeric compounds, specializing in "soft touch" technology for the automotive industry.

Americhem will celebrate its 75-year anniversary on November 29, 2016.
