Data<\/strong><strong><\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\"><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Silicone oil is commonly used in printing-pad manufacture to reduce the hardness of the cured pad.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Industry suppliers such as <a href=\"https:\/\/www.elkem.com\/markets\/advanced-manufacturing-industrial\/molding-printing\/pad-printing\/\" target=\"_blank\" rel=\"noopener\"><u>Elkem<\/u><\/a>&nbsp;also describe RTV printing-pad systems whose hardness can be adjusted through silicone-oil dilution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Topsil silicone has internal hardness-adjustment reference data using <strong>A100 silicone oil<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How the Dosage Is Calculated<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The percentages below are calculated <strong>based on the total mixed weight of Part A + Part B silicone before the silicone oil is added<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u0639\u0644\u0649

Test?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">First, silicone-oil addition can change finished-pad hardness dramatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Second, the relationship is clearly <strong>not linear<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Moving from 10% to 20%, for example, does not produce the same hardness reduction as moving from 60% to 70%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This means hardness adjustment should be based on actual formulation data rather than a simple assumption such as:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cEvery additional 10% oil reduces hardness by X Shore A.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It does not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What This Test Does Not Prove<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This distinction is important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The test series above measured the resulting <strong>\u0635\u0644\u0627\u0628\u0629 \u0627\u0644\u0634\u0627\u0637\u0626 A<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Topsil silicone has <strong>not yet measured tensile strength, tear strength and elongation at every A100 dosage shown in this table<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, we do not claim that a pad containing 30%, 50% or 70% A100 retains the original mechanical properties listed on the unmodified PP-30 or AP-30 TDS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hardness data demonstrates hardness change. It does not prove unchanged mechanical performance.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why an oil-adjusted formulation should be treated as a new pad formulation and validated accordingly.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Don&#8217;t Choose Silicone Oil Only to Reach a Shore Number<\/strong><strong><\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\"><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose a manufacturer needs a finished pad of approximately 13 Shore A.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Topsil silicone reference data suggests that <strong>around 30% A100<\/strong>, based on total A+B mixed silicone weight, may be a practical starting reference in the tested system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But reaching 13 Shore A is not the final qualification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The next questions are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Does the pad deform correctly?<\/li>\n\n\n\n<li>Does it recover consistently?<\/li>\n\n\n\n<li>Does it tear prematurely?<\/li>\n\n\n\n<li>Is ink pickup and release acceptable?<\/li>\n\n\n\n<li>Does it maintain image geometry?<\/li>\n\n\n\n<li>How many useful production cycles does it achieve?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correct development sequence is therefore:<\/p>\n\n\n\n<p

class=\"wp-block-paragraph\">The complete selection process can now be reduced to ten practical steps:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 1 \u2014 Define the substrate<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">What material and surface are being printed?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 2 \u2014 Define

design<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Shape, dimensions, volume and compression behavior.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 5 \u2014 Establish the hardness direction<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Always state the Shore scale.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 6 \u2014
