All rights more than 55 years experience in Silicone technology, Dow Corningunderstands customer needs and applicationrequirements like no other supplier. And weoffer a complete line of high-consistencysilicone Rubber Bases for a wide range of uses,as well as an extensive array of modifiers andpigment masterbatches.

2 If you have any doubts about elastomerperformance in a new or existing application,contact us for information on Silastic brandsilicone Rubber tackles the jobs conventionalelastomers can tSilasticsilicone Rubber from Dow Corning isnoted for its ability to function under condi-tions that would damage many conventionalmaterials. When fully compounded and cured, Silicone Rubber typically offers thermal stabil-ity from -50 C to 200 C, and is unaffected byextreme weather conditions, ultraviolet radia-tion, ozone and many fluids. It also deliversoutstanding electrical insulating Rubber can be found in amyriad of applications on automobiles, air-craft, home appliances, computers, industrialequipment and beyond.

General Purpose (GP):formulated with awell-balanced combination of tear resistanceand compression set, usable for extrusion,molding or calendering in a hardness rangefrom 20 to 80 Shore A High Strength (HS):formulated to deliver acombination of high tensile strength andhigh tear strength.

4 Tough Rubber (TR):provide a combinationof high tensile strength, very high tearstrength and high modulus. Low Compression Set (LCS):speciallydeveloped for low compression set (typically10-16 percent) when vinyl-grade peroxidesare used. Low Temperature (LT):offer a brittle pointas low as -116 C. No Post Cure (NPC):low compression setwithout post curing. Wire & Cable (WC):combine excellentextrusion properties with electrical insulatingperformance. Semi-Conductive:contain carbon fillers toincrease electrical conductivity.

6 In short,we deliver the highest quality materialscoupled with the global collective knowledgeof Silicone Rubber experts worldwide to meetyour company s needs. Processing couldn t beeasierSilasticsilicone Rubber Bases are supplied asmillable materials that are peroxide-cured withheat. They offer outstanding versatility: Molding:a wide variety of part shapes andsizes can be compression-, transfer- orinjection-molded. Extrusion:efficient production of tubing,hose, rods, seals, wire insulation and jacketing. Calendering:selected Bases can becalendered into long, thin sheets of uniformthickness, either unsupported or fabricreinforced.

7 Dispersion coating: Bases and compoundscan be dispersed in solvents to coat avariety of fabrics or other substrates. Heatcure follows solvent final Rubber compound usually containsone or more of the Bases described in thisbrochure, in combination with additives,extending fillers, pigments and catalysts. Weoffer several additives and a wide range ofpigment masterbatches to make compoundingeasier. Additives from Dow Corning include: - Heat stabilizers- Flame retardants- Viscosity modifiers- Handling aids- Internal mold release agents Pigment masterbatches help customersachieve virtually any color.

8 Translucent tooff-white Bases are mixed with pastepigments instead of powders for easy andefficient coloring. Silicone Rubber Bases are normally vulcan-ized using peroxide catalysts. These catalystsare available from several sources. Finalrubber properties vary depending on thecatalyst used. Dow Corning 2AV03636AV04626AV04625AV04624 Product specs?
