FDA Food Grade Silicone Gaskets And Seals Fungus Resistant
Introduction:
Hongum specializes in precision die cut and molded silicone rubber gaskets and seals for applications and industries worldwide. Silicone rubber is a high-performance elastomer with exceptional resistance to temperature extremes. Silicone molded and die cut gaskets remain functional within a temperature range of -67°F to +400°F, intermittent to +450°F. The low temperature flexibility of silicone is unmatched by any other elastomer. Silicone gaskets are often chosen due to their excellent resistance to chemicals, water, fire, fungal growth, ozone, heat and aging. Silicone has outstanding tensile strength, elongation, tear strength, and compression set. The versatility and long service life of silicone make it ideal for a wide variety of applications.
Hongum provides precision die cut and molded FDA (Food Grade) silicone rubber gaskets and seals. Our FDA approved silicone products are provided to meet all of your blueprint specifications and tolerance requirements in order to suit your particular application. All food grade silicone products we manufacture are FDA compliant and provide reliable service at temperatures ranging from -175°F to 482°F. Food Grade (FDA) silicone is odorless, tasteless, peroxide-free, and fungus resistant making it ideal in applications where food is present.
The main products of rubber sealing gaskets are: silicone pads, nitrile rubber pads, fluorine rubber pads, and other rubber pads.
Die Cut Silicone Gaskets
Hongum provides die cut silicone gaskets in a wide variety of grades, thicknesses, and hardness. The standard thickness of silicone rubber ranges from .010″ to 1″ thick. Silicone rubbers hardness (durometer) typically spans from 30 to 80 durometer, Shore A. We inventory a full spectrum of colors including red/orange, black, gray, blue, white, and translucent. Silicone rubber gaskets are available with or without acrylic or high temperature pressure sensitive adhesive (PSA) backing.
Molded Silicone Gaskets
Hongum provides molded silicone gaskets and seals. Our custom molding capabilities include Compression Molding, Transfer Molding, Rubber Injection Molding, and Silicone Liquid Injection Molding (LIM). We commonly mold products using silicone, fluorosilicone, and FDA (food grade) silicone compounds which are available in color options red/orange, black, gray, blue, white, and translucent with custom color compounding available upon request. Silicone rubber molding compounds durometer (hardness) typically ranges from 25 to 80 durometer, Shore A. Silicone rubber molding tolerances are compliant with rubber molding industry standard RMA A2 Precision tolerances.

The sealing washer is affected by the material and process of the threaded fasteners, and most of the supporting surfaces of the fastened parts of the bolts will not be very large, thus reducing the pressure to protect the surface. In order to prevent the loosening of the connection pair, anti-loose sealing spring washers, multi-tooth locking sealing washers, round nut stop sealing washers and wave-shaped and conical elastic washers are used. The gasket is mainly used to reduce the pressure. When some parts are tightened with a large axial force, the gasket is easy to be pressed into a dish shape. At this time, it can be solved by changing the material and increasing the hardness.
