Our Founders

Oscar and Eric Spiegelhalder, owners of Sunhill Corporation and Holloway Sucrochemicals, Inc. bought the license for Kenflex manufactured in the 1950’s and produced the resin as an adjunct plant to their sucro chemical production in Maspeth, NY. Upon approval by *DuPont^®, a 10,000 lb./day manufacturing plant was constructed in Bayonne, NJ in 1961. The 6.5-acre site was purchased by Kenrich Petrochemicals, Inc. in 1978 where it operates today as a three-generation family owned business.
