GLUETEX offers a wide selection of Hotmelt adhesive films for different applications for the automotive industry. Whether for the production of airbags, door covers or car mats. GLUETEX Hotmelt adhesive films provide a reliable and strong bond - day in and day out.
GLUETEX Hotmelt films are increasingly replacing conventional liquid adhesives. They are solventfree and therefore particularly environmental friendly.
Hotmelt adhesive film is mainly activated by heat, ultrasound or high frequency. Through the supply of heat onto the film, the adhesive becomes slightly liquid and cross links with the surrounding materials. Once the heat supply is stopped, the Hotmelt cures in seconds and ensures a strong bond.
Benefits of Hotmelt films at a glance:
Adhesive joints are uniformly dense
Easy to handle
Easy job preparation
Long shelf life
Rapid activation and setting time of the Hotmelts
Glued joint is resistant after a short time
GLUETEX offers both solid and perforated adhesives for bonding foam to fabric (seat cushion) or foam backed fabric. Adhesive selection is driven by price, softness, breathability (through perforation) and heat resistance. Some seat constructions include a layer of resilient wadding for added support.
Typical application procedure: Seat fabric is prelaminated with adhesive film using a continuous fusing press or hot drum laminator.
Bond adhesive coated seat fabric to cushion foam or wadding. Bonding method varies depending on your application equipment.
Activation of the prelaminated adhesive to bond to the seat cushion is possible with the use of heat and pressure, steam, or hot air. Adhesive Films are also used to bond the layers within seat heating elements. This multilaminate construction requires a heat activated adhesive with sufficiently high heat resistance and a in most cases, a certain minimum flame retardant characteristic.
GLUETEX products are used in the construction of seams in air bags. Typically a seam sealing tape or adhesive is used to reduce air loss during inflation.
Typical application procedures: Using a hot air welder, seam tape is applied over a stitched seam to prevent the air from escaping through the stitch holes.
Adhesive tape is sewn into the seam during bag construction. The fabric with stitched-in tape is placed in an RF sealing fixture. The adhesive is activated by the RF tool and flows into the stitch holes, effectively creating a hermetic seal.
Adhesive tape is used to bond the air bag together without sewing and to avoid stitches in the textiles. A hot air or hot wedge machine is used to activate the adhesive and seal the adjoining fabrics of the air bag.
