Single-Use Silicone

Newman Sanitary Gasket Co. is a leading USP Class VI & Platinum-Cured Silicone Sanitary Gasket Manufacturer of both FDA grade and USP Silicone sanitary gaskets and O-rings around the world. Newman peroxide and platinum-cured silicone compounds are known for their relative purity, safety, optical clarity, ease of use, and low levels of extractable material. This makes Newman silicone seals the first choice in many high purity applications including in Single-use biopharmaceutical gaskets and assemblies. Silicone’s wide temperature range keeps it flexible from steaming to almost cryogenic temperatures. Its chemical resistance allows it to be used a wide variety of static and dynamic applications. Silicone, however, has only moderate toughness/durability and tends to absorb process materials more than other materials. Because of this, it is not as popular in Multi-use applications where equipment is repeatedly cleaned and steamed-in-place.

Silicone Products

Newman manufacturers a full range of precision USP Class VI, single-use, and platinum-cured silicone sanitary gaskets, O-rings, extruded shapes and custom parts. They are available in a variety of hardness’s and colors for the food, beverage, and pharmaceutical processing industries. A full range of relevant certifications (FDA, USP, EP, ICH, REACH, RoHS, etc.) is also available.

Our silicone products are manufactured in a range of clean spaces to avoid cross-contamination and control bioburden and particulates as required. From a single manway gasket to hundreds of thousands of gamma-irradiated single-use gaskets, Newman is your one-stop shop for silicone seals.
