Steralloy™ FDG - Elastomeric

Elastomeric Series

Various hardness elastomers, shore 20A - 72D
Clear in color
Available in 2 speeds - fast and slow

STERalloy FDG is the first Liquid Molding Polymer Alloy Series that has been specifically designed for food and drug applications. All of the products in the STERalloy FDG Series exhibit unique physical and chemical properties, are manufactured with FDA approved material, and have excellent processing properties. STERalloy FDG Series fills the high current demand for products that are used in food and drug applications.

The food, drug, pharmaceutical, wine, beer, juice, dairy, hospital equipment, and prosthetic industries are just some examples of applications that require special products such as STERalloy FDG.

NOTE: These products may have a negative reaction to silicone based rubbers and release agents. For best results, use Hapco's Hapsil 360 silcone rubber without any release agent. Contact a Hapco representative for more information.
