mathematical model for calculating thermal resistance is used, presented above on the site page &quot;DESCRIPTION - Thermal resistance of KPTD materials&quot;.

For materials with a thickness of 0.25-1.0 mm at a compression stress of up to 0.7 MPa, the change in thickness during compression can be calculated with sufficient accuracy using formula 5, taking into account dependence 11 of the section &quot;DESCRIPTION - Elasticity (compressibility) of KPTD materials&quot;. With a further increase in the compressive stress, the thermal resistance depends only on the residual thickness of the material. When an additional adhesive layer or positioning grease is applied, the total specific thermal contact resistance for thin sheets decreases slightly (see value <strong><em>R<sub>0S<\/sub><\/em><\/strong>).<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><a href=\"http:\/\/nomacon.by\/wp-content\/uploads\/kptd-sopr-2m_01.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/nomacon.by\/wp-content\/uploads\/kptd-sopr-2m_01.jpg\" alt=\"Thermal resistance of materials KPTD-2M\" class=\"wp-image-921\" width=\"368\" height=\"461\"\/><\/a><figcaption>Thermal resistance of materials KPTD-2M\n<\/figcaption><\/figure><\/div>\n\n\n\n<p>The value of thermal resistance of gaskets made of various grades and thicknesses of KPTD-2M materials can be determined using the following values <strong>empirical coefficients:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>sheet material KPTD-2M \/ 1 R<sub>S<\/sub> = 0.23 (K\u22c5 cm\u00b2) \/ W, R<sub>0S<\/sub> = 0.19 (K\u22c5 cm\u00b2) \/ W, \u03bb = 0.87 W \/ (m\u22c5K);<\/strong><\/li><li><strong>sheet material KPTD-2M \/ 2 R<sub>S<\/sub> = 0.23 (K\u22c5 cm\u00b2) \/ W, R<sub>0S<\/sub> = 0.19 (K\u22c5 cm\u00b2) \/ W, \u03bb = 1.14 W \/ (m\u22c5K);<\/strong><\/li><li><strong>sheet material KPTD-2M \/ 3 &nbsp;&nbsp;&nbsp;<\/strong> R<sub>S<\/sub> = 0.23 (K\u22c5 cm\u00b2) \/ W, R<sub>0S<\/sub> = 0.19 (K\u22c5 cm\u00b2) \/ W, \u03bb = 1.44 W \/ (m\u22c5K);<\/li><li><\/li><li>The above mathematical model for calculating the thermal resistance of sheet materials KPTD-2M at compressive stresses up to 1.7 MPa gives good convergence of the results provided that the requirements for compressive contact surfaces are met, which are presented in the section &quot;Instructions for use&quot;.<\/li><\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>Example 3.<\/strong><\/p><\/blockquote>\n\n\n\n<p>In the conditions of example 1 (see the section of the website \"Heat-conducting electrical insulating compounds KPTD-1\"), the motor controller board for the purpose of complex heat removal is installed in an aluminum case through a heat-conducting electrical insulating gasket made of NOMACON \u2122 KPTD-2M \/ 1-0.50 material.

Before use, mark and cut the required spacer without removing the protective films from the surface of the material. Then peel off the front protective film and adhere the gasket to one of the heat transfer contact surfaces. Carefully peel off the second protective film from the gasket and press the other heat transfer surface against the surface of the material.<\/li><li>Determine the required compression force of the contact surfaces between which the gasket is installed. It should be borne in mind that the nominal working compressive stress (MPa) determines the permissible relative deformation of the material sheet in the range from 10% to 50 % from its original thickness, at which the manufacturer guarantees the strength, electrical insulating and heat-conducting properties presented in the table &quot;Technical characteristics&quot;.<\/li><li>The ultimate compressive stress determines the relative deformation of the material within the range of up to 50% from its original thickness, at which there is no loss of elasticity, and subsequently, when the compressive stress is removed, the material is restored to its original thickness and retains its properties. Operation of gaskets made of KPTD-2M material when exceeding the limiting compression stress is not allowed.<\/li><li>The quality of the compressive surfaces (the device and the radiator must comply with GOST 265 in order to achieve the normalized heat transfer properties of the gasket. The roughness of the compressive surfaces should not exceed Ra = 0.63 \u03bcm in accordance with GOST 2789. The deviation of the geometry of the compression surfaces in terms of flatness and parallelism should not exceed the degree of accuracy 7 in GOST 24643. The presence of burrs and other defects on the contact surfaces can violate the integrity of the gasket, and, accordingly, the required electrical insulation.<\/li><li>The efficiency of heat removal through a gasket made of material is determined by the compressive force of the surfaces of the device and the radiator, their flatness and parallelism during assembly, as well as the presence of residual air cavities between the gasket and the clamping surfaces. In order to maximize the squeezing out of air pockets, it is recommended to apply the gasket with a glossy surface or a surface with a sticky layer to the highest quality pressure surface and roll it with a rubber roller.<\/li><li>To isolate semiconductor devices from the heatsink housing when fastening with screws, use insulating sleeves NOMACON \u2122 M2.5 and M3 made of heat-resistant polyamide.<\/li><li> When using large format gaskets with a surface area of 20 to 1200 cm\u00b2, there is often a problem of high-quality preparation of contact surfaces. At the same time, the thickness and elasticity of the gasket is not enough to compensate for the defects of the surfaces themselves during compression, as well as their flatness and parallelism during assembly. In order not to increase the thickness of the gasket, leading to an increase in thermal resistance, it is recommended to first apply the appropriate heat-conducting paste NOMACON \u2122 KPTD-3 to the contact surfaces and then install and roll the gasket.<\/li><li>It is prohibited to store, manipulate and use the KPTD-2 (KPTD-2M) materials at temperatures below minus 60 \u00b0 C and above plus 250 \u00b0 C.<\/li><\/ol>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><a href=\"http:\/\/nomacon.by\/wp-content\/uploads\/kptd-list-img1a.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"567\" height=\"292\" src=\"http:\/\/nomacon.by\/wp-content\/uploads\/kptd-list-img1a.jpg\" alt=\"Instructions for the use of KPTD-2M\" class=\"wp-image-924\"\/><\/a><\/figure><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">manufacturer&#039;s warranty<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li>The manufacturer guarantees the conformity of NOMACON \u2122 KPTD-2M sheet materials to the requirements of technical specifications, subject to the conditions of transportation, storage and use.<\/li><li>The shelf life of KPTD-2M materials without a sticky layer in the manufacturer&#039;s packaging is 24 months.<\/li><li>The shelf life of KPTD-2M materials with a sticky layer and positioning grease in the manufacturer&#039;s packaging is 6 months.<\/li><li>The loss of stickiness of KPTD-2M materials after the expiration of the consumer&#039;s shelf life is not a rejection factor.<\/li><li>After the expiration of the shelf life, the KPTD-2M materials are tested before each use for compliance with the technical requirements.
