Utilizing the most efficient materials and designs, Tompkins Pharmaceutical Rubber delivers high quality butyl rubber stoppers. Backed by our Drug Master File formulations and FDA approved materials, Tompkins’ manufacturers supply first-rate stoppers to our medical clients.

Butyl rubber compounds are heat resistant, exhibit very low gas transmission properties and possess moderate resistance to various oils and solvents. Blends may be made to enhance both processability and end-use properties.

Tompkins’ large number of DMF listed material formulations allows for satisfaction of the specific end-use need.
