A new high-tech adhesive tape portfolio, the DuploCOLL® LE 59xxx range, which offers low emission and low odour products for bonding applications in vehicle interiors, has been launched by Lohmann – a long-standing development partner to the automotive industry.
The double-sided, pressure sensitive, DuploCOLL® LE 59xxx tapes meet OEM requirements for low VOC, fogging and odour values for materials and components in accordance with VDA 278. Even large area applications requiring a considerable amount of tape, such as bonding rear seat covers, and pillar or door-trim NVH insulation felts, do not adversely affect the interior air quality.
The low emission tapes have been produced using sustainable manufacturing processes. A low carbon footprint, water and energy saving process – using 100% solvent free, TwinMelt® technology based on UV acrylates, with enhanced adhesive performance and further value chain sustainability – is achieved through the use of recyclable liners in the production process. In addition, as no gas is used as an energy source in tape production, this offers a high-level of fuel supply security for customers.
The new tape portfolio enables a wide variety of designs to be made in different materials, such as plastic or wood effect, which can be firmly adhered even on low energy material surfaces – thanks to the tapes’ high initial adhesion and adhesive strength properties. Uses for the tapes, which have been shown in tests to perform well at elevated temperatures, include taping heating systems in seats, armrests and steering wheels, surface heating systems, as well as door panels or dashboards in electric vehicles.
In addition to full surface bonding, an adhesive-stripe coating can be applied, due to its special geometry, for example when bonding heating elements to seats – ensuring that air can still circulate, thus ensuring the seat stays optimally ventilated. The portfolio can also be used to reliably bond sensor systems, such as Hands-Off Detection (HOD) or Driver Presence Detection (DPD) systems.
In combination with flexible and elastic polyethylene foam carriers, the low emission tapes enable compensation of component tolerances, sealing, vibration damping and are easy to process thanks to their dimensional stability. The broad portfolio includes a selection of transfer, paper, scrim, film and foam tapes in various thicknesses, from 0.03mm to 0.8mm. The tapes in this new DuploCOLL® LE portfolio can also be laminated with a wide range of damping materials, such as felts, foams, textiles or knitted spacer fabrics, as well as customised materials for use as a single-sided adhesive NVH (noise, vibration, harshness) solution, including soft-touch surfaces that produce a pleasant feel. The entire portfolio is available as rolls, spools or die-cuts in individual formats.
