NSF CERTIFIED MATERIALS

NSF standards 51 and 61 are in place to protect consumers against food and water contamination. These standards provide manufacturers and distributors a baseline for the minimum public health and sanitation requirements of drinking-water related products. They also apply for materials used in the construction of commercial food and water containment equipment. Regulations apply to every step of the manufacturing process, so it is extremely important to comply with NSF standards if your part is in use in North America.
 

NSF CERTIFIED SANTOPRENE TPV

One of the materials that Sherwood Industries Inc. extrudes is made with Santoprene™ Thermoplastic Vulcanizate (TPV) from Celanese. Santoprene TPV is a blend of polypropylene and EPDM rubber meaning it behaves like a rubber but processes like a thermoplastic. This material is a high performance elastomer that provides consistent performance and chemical resistance.
 
Certain grades of Santoprene TPV are in compliance with NSF/ANSI 51, which involves food equipment materials, NSF/ANSI/CAN 61, which involves drinking water system components, UL QMFZ2 for plastics and UL QMFZ8 for plastics certified in Canada. NSF certified Santoprene TPV is standard in plumbing parts, potable water seals and tubing. The grades with the W236 designation are stabilized against copper and other metal-catalyzed degradation. Sherwood makes it easy for businesses to operate within these strict standards by providing NSF certified Santoprene which allows for immediate compliance.
 

SHERWOOD’S CAPABILITIES

We can extrude sheet from 0.020” to 0.250” (0.6 mm to 6.3mm) thick. We offer widths between 6” to 36”. Our extruded sheet can be wound onto 3″ or 6″ PVC cores. Our machinery allows for flexibility on the amount of linear feet wound on each roll or a certain weight limit per roll. With four patterns and color matching capabilities, we can provide you with a customized product for your application. We can accommodate orders ranging from 500 pounds to truckloads, shipped worldwide.

We also offer profile extrusion to provide shapes and configurations to match your products’ exact requirements for your unique application. We make custom dies to extrude a shape that fits your requirements and will assure a consistent and reliable part over years of extrusion. Profile parts can be cut to length or wound into a roll.
