PUR foam 1612｜Polyurethane Formed-In-Place Foam Gasket Sealant, Simplifying Sealing for Complex Housings!

One-pass dispensing, in-situ foaming, seamless forming. PUR foam 1612 Foam Sealant For electrical control boxes, industrial cabinets, automotive electronics housings and new energy equipment, sealing performance is critical not only for dustproof and waterproof functions, but also directly impacts product assembly efficiency, production tact time and long-term operational reliability. For housing sealing structures with complex geometries, ELAPLUS PUR foam 1612 polyurethane formed-in-place foam gasket sealant is recommended. This product is developed around the FIPFG (Formed-In-Place Foam Gasket) process. With two-component metered dispensing, it forms a continuous foam gasket along the sealing zone of workpieces, delivering a flexible sealing solution for complex contours, irregular grooves and automated production lines. The shift from traditional prefabricated gaskets to formed-in-place foam sealing changes not only the material form, but the entire sealing workflow. 01｜Why Choose PUR Foam 1612? Shifting sealing from pre-assembled gaskets to on-site forming Conventional rubber gaskets require custom moulds according to housing contours, followed by gasket fabrication and manual or machine installation. For electrical control boxes and equipment housings with complex structures and multiple variants, numerous gasket specifications raise costs for mould development, material management and assembly. FIPFG (Formed-In-Place Foam Gasket) technology offers an alternative: automated dispensing equipment applies adhesive directly along pre-defined paths on workpieces. The material foams and cures in situ to form a continuous sealing bead. The application benefits of PUR foam 1612 lie mainly in three aspects: 02｜Two-Component Mixing, In-Situ Chemical Foaming From liquid adhesive to elastic foam gasket PUR foam 1612 adopts the polyurethane formed-in-place foam gasket technology. During application, the two components are metered and blended by dispensing equipment, then deposited onto workpiece surfaces or sealing grooves along programmed paths. Chemical reaction generates foam structures which cure gradually. Unlike conventional non-foaming sealants, formed-in-place foam sealants expand after dispensing and change cross-sectional geometry, yielding foam seals…
