Recente ontwikkelingen in reactieve Smeltlijm polyurethaan<\/span> (HMPUR) adhesive technology have made these products viable candidates for use in high performance applications. Specifically,\r\n technical advantages that combine desirable properties such as past set (curing), rapid green strength development, and exceptional environmental resistance, are now available.<\/p>\r\n <\/div>\r\n <\/div>\r\n

Wat is PUR-smeltlijm (HMPUR)?<\/h5>\r\n <\/div>\r\n <\/div>\r\n
\r\n \r\n \r\n
\r\n

HMPURs zijn het reactieproduct van de combinatie van een polyol en een isocyanaat<\/span>. Once reacted, the product formed is an isocyanate terminate prepolymer, which is moisture\r\n sensitive. After application, this product cross-links through a reaction with moisture in the air and surrounding substrates, forming a thermoset polyurethane polymer. Once thermoset, the HMPUR will possess exceptional\r\n strength and durability. Because these products contain isocyanates and must be heated for application, our partners work with lesser volatile isocyanates, such as MDI (difenylmethaandiisocyanaat).

Hoe werkt het?<\/h5>\r\n <\/div>\r\n <\/div>\r\n
\r\n \r\n \r\n
\r\n

HMPUR's werken via twee verschillende fasen<\/span> om de eigenschappen van een hoogwaardige lijm te ontwikkelen. In de eerste fase<\/span>, wordt de HMPUR verwarmd om smeltbaar of vloeibaar te worden voor het aanbrengen. In dit stadium is HMPUR vergelijkbaar met conventionele smeltlijmen doordat thermische afkoeling de lijm na het aanbrengen laat stollen. Dienovereenkomstig heeft HMPUR een open tijd en een insteltijd. Deze ontwikkelt bij afkoeling voldoende sterkte om het in-line trimmen en andere handelingen van onderdelen mogelijk te maken.<\/p>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n

vochtuitharding<\/h5>\r\n <\/div>\r\n <\/div>\r\n
\r\n \r\n \r\n
\r\n

In de tweede fase<\/span>, reageert HMPUR met vocht en vormt zo een thermohardend polymeer dat bestand is tegen hitte, vocht, kou en oplosmiddelen. Deze reactie vindt in de loop van de tijd plaats en onder normale\r\n omstandigheden is de uitharding binnen de eerste 24 uur voltooid.\u00a0Naarmate de verknoping voortduurt, zullen de samengestelde substraten steeds sterker worden. Normale omstandigheden bij 50% relatieve vochtigheid en 21\u00b0<\/span>C.<\/p>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n

Gelamineerde substraten die zijn verlijmd met HMPUR worden zeer duurzaam. De lijmverbinding vertoont vele belangrijke eigenschappen:<\/p>\r\n

Neem gerust contact met ons op als u uitgebreid advies nodig hebt over het werken met HMPUR. Er is een enorme omvang<\/span> van verschillende HMPUR-typen. Het is daarom erg belangrijk om alle vereisten van de laminering te begrijpen voordat u de juiste HMPUR kiest.\r\n

HMPUR wordt voor veel verschillende toepassingen gebruikt, voornamelijk laminering. Enkele voorbeelden zijn:<\/p>\r\n

Vlakke laminering: hout op paneel, hout op folie, metaal op hout, enz.\r\n
\r\n <\/p>\r\n

\r\n \r\n Flexibele laminering<\/u>\r\n <\/a> (rol naar rol): Textiel op textiel, textiel op membraan, textiel op schuim, enz.\r\n
\r\n <\/p>\r\n

Profielommanteling: folie op PVC-profiel, folie op aluminium profiel, enz.\r\n
\r\n <\/p>\r\n

Montage: Delen gelijmd in structuur, enz.\r\n
