VMQ Rubber Diaphragm Seals Polysiloxane Silicone Rubber Gaskets Chemicals Resistance
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.
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.
Conductive Silicone Gaskets
Hongum provides precision die cut conductive silicone gaskets and seals. Conductive Silicone is a unique composite of high-quality silicone and conductive microscopic particles which are commonly used for electronic applications. These elastomers are filled with special conductive fillers such as; carbon, nickel, silicone plated glass, silver plated nickel, silver plated aluminum, silver plated copper, silver and reinforced silver plated copper to be either thermally or electrically conductive.
