However, it&#8217;s essential for clients to know the general processes and raw materials involved in silicone rubber production.<\/p>\n\n\n\n<p>Let\u2019s begin with <strong>Vinyl Silicone Fluid<\/strong>, a type of polysiloxane that contains two or more -Si-CH=CH2 groups. It is a key ingredient in silicone rubber. By adding Vinyl Silicone Fluid, the rubber\u2019s crosslink density is altered, enhancing its tear strength, tensile strength, and hardness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Key Components of Platinum Cure Silicone Rubber:<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Silicone Base<\/strong><br>The primary component of platinum silicone is often <strong>Polydimethylsiloxane<\/strong>, which contains two or more -Si-CH=CH2 groups. Typically, it is a type of linear polysiloxane, where vinyl groups are attached at both ends. (If only one vinyl group is present at one end, it is referred to as Vinyl Silicone Oil.)<\/li>\n\n\n\n<li><strong>Crosslinker<\/strong><br>The <strong>Crosslinker<\/strong> is an organic silicon oligomer containing three or more -Si-H groups, commonly called <strong>methyl hydrogen silicone oil<\/strong>. It is one of the fundamental ingredients in platinum cure silicone rubber.<\/li>\n\n\n\n<li><strong>Platinum Catalyst<\/strong><br>Several catalysts can initiate the Si-H reaction in addition-cure silicone rubber, but platinum is the most efficient. Using a platinum catalyst allows the silicone rubber to vulcanize at room temperature. By adding an inhibitor in the right proportion, the reaction speed and vulcanization process can be controlled.<\/li>\n\n\n\n<li><strong>Reinforcement Fillers<\/strong><br>Silicone rubber made from Vinyl Silicone Fluid and Hydrosilicone Fluid alone does not exhibit strong mechanical properties, such as tear strength, tensile strength, or elongation. To improve these characteristics, <strong>reinforcement fillers<\/strong> like fumed silica, precipitation silica, or silicon powder are added. For clear silicone rubber, <strong>Methyl Vinyl MQ Silicone Resin<\/strong> is used to enhance its mechanical properties.<\/li>\n\n\n\n<li><strong>Other Additives<\/strong><br>Various additives are included to achieve specific properties like different colors, improved thermal conductivity, flame resistance, electrical conductivity, thermostability, transparency, and more.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>For years, many silicone rubber manufacturers have focused primarily on marketing their products, without providing a clear understanding of how silicone rubber is made and what its components are.
