However, because of polyurethane&#8217;s tendency to emit volatile organic compounds that can cause problems , it is being phased out of the mattress and upholstery industries and replaced by more environmentally friendly materials.<\/p>\n<p>When considering insulation and fire-fighting measures, closed-cell silicone foams definitely have the upper hand because they are completely flexible over a very wide temperature range and are fire retardant. As a result, they have proven useful in the thermal management of electric vehicle batteries. In addition, they can be used on any surface regardless of their environment due to silicone&#8217;s extreme weather resistance and resistance to harsh chemicals and UV rays.<\/p>\n<p><u>Overall, silicone foams can be used in a wider range of applications than polyurethane foams, without having the adverse health effects of polyurethanes.<\/u>[\/vc_column_text][divider line_type=&#8221;No Line&#8221;][image_with_animation image_url=&#8221;16874&#8243; image_size=&#8221;full&#8221; animation_type=&#8221;entrance&#8221; animation=&#8221;Fade In&#8221; animation_easing=&#8221;default&#8221; animation_movement_type=&#8221;transform_y&#8221; hover_animation=&#8221;none&#8221; alignment=&#8221;center&#8221; border_radius=&#8221;15px&#8221; box_shadow=&#8221;none&#8221; image_loading=&#8221;default&#8221; max_width=&#8221;100%&#8221; max_width_mobile=&#8221;default&#8221;][divider line_type=&#8221;No Line&#8221;][vc_column_text]<strong>A silicone foam to consider<\/strong><\/p>\n<p><strong>DOWSIL 3-6548 RTV<\/strong> silicone foam is a two-component, medium-density foam that is ideal for sealing fire crossings in systems containing cables and pipes. It can prevent the penetration of smoke and gases through seals by forming irregular and complex shapes around the components it is protecting. It is composed of two liquids that mix in a 1:1 ratio, expanding and curing at room temperature to form an elastomer. Like all silicone foams, it is non-corrosive, flame retardant, and resistant to UV rays and extreme temperatures. It also meets HL3\/R22 of the railway standard EN45545, making it an excellent choice for use in the railway industry.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/mascherpa.it\/en\/blog\/what-are-the-advantages-of-silicone-foam-over-polyurethane-foam\/\" class=\"excerpt\">[vc_row type=&#8221;in_container&#8221; full_screen_row_position=&#8221;middle&#8221; column_margin=&#8221;default&#8221; column_direction=&#8221;default&#8221; column_direction_tablet=&#8221;default&#8221; column_direction_phone=&#8221;default&#8221; scene_position=&#8221;center&#8221; text_color=&#8221;dark&#8221; text_align=&#8221;left&#8221; row_border_radius=&#8221;none&#8221; row_border_radius_applies=&#8221;bg&#8221; overflow=&#8221;visible&#8221; overlay_strength=&#8221;0.3&#8243; gradient_direction=&#8221;left_to_right&#8221; shape_divider_position=&#8221;bottom&#8221; bg_image_animation=&#8221;none&#8221;][vc_column column_padding=&#8221;no-extra-padding&#8221; column_padding_tablet=&#8221;inherit&#8221; column_padding_phone=&#8221;inherit&#8221; column_padding_position=&#8221;left&#8221; column_element_direction_desktop=&#8221;default&#8221; column_element_spacing=&#8221;default&#8221; desktop_text_alignment=&#8221;default&#8221; tablet_text_alignment=&#8221;default&#8221; phone_text_alignment=&#8221;default&#8221; background_color_opacity=&#8221;1&#8243; background_hover_color_opacity=&#8221;1&#8243; column_backdrop_filter=&#8221;none&#8221; column_shadow=&#8221;none&#8221; column_border_radius=&#8221;none&#8221; column_link_target=&#8221;_self&#8221; column_position=&#8221;default&#8221; gradient_direction=&#8221;left_to_right&#8221; overlay_strength=&#8221;0.3&#8243; width=&#8221;1\/4&#8243; tablet_width_inherit=&#8221;default&#8221; animation_type=&#8221;default&#8221; bg_image_animation=&#8221;none&#8221; border_type=&#8221;simple&#8221; column_border_width=&#8221;none&#8221; column_border_style=&#8221;solid&#8221;][image_with_animation image_url=&#8221;16872&#8243; image_size=&#8221;full&#8221; animation_type=&#8221;entrance&#8221; animation=&#8221;Fade In&#8221; animation_easing=&#8221;default&#8221; animation_movement_type=&#8221;transform_y&#8221; hover_animation=&#8221;none&#8221;&#8230;<\/a><\/p>\n","protected":false},"author":4,"featured_media":20931,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3189,3275,3207],"tags":[3259,3476,3449,3477],"class_list":{"0":"post-22218","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-conttto","8":"category-gaskets-and-o-rings","9":"category-silcone-sealant-adhesives","10":"tag-dowsil-en","11":"tag-gasketing-en","12":"tag-silicone-adhesives","13":"tag-silicone-gaskets"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What are the advantages of silicone foam over polyurethane foam? | Mascherpa s.p.a<\/title>\n<meta name=\"description\" content=\"What are the advantages of silicone foam over polyurethane foam?
