Elastan® (PU):
High-quality and ultra versatile adhesive solutions
Elastan® is a MDI-based binder/adhesive in the form of one or two component systems for various applications and substrates. BASF offers a complete portfolio of adhesives for sandwich panels, outdoor flooring binder solutions, woodfibre insulation panels and as adhesion promoter.
The best solutions result from dialogue and cooperation. That is why BASF is always close to the markets and customers worldwide, creating products which exactly meet their individual requirements. In this well proven way we have also developed and expanded our portfolio of binders and adhesives applicable for various application areas.
Everything from one source: BASF offers a complete portfolio of Elastan® adhesives for construction elements. Our adhesives are ideally suited for a wide range of different core and facing materials such as PU foam, mineral wool, glass wool, EPS (expanded polystyrol) as well as metal and fiberglass-reinforced polyester. All other core materials can be tailored to the respective requirements.
The Elastan® adhesive systems for mineral wool or glass wool are offered as filled and unfilled 2-component or 1-component systems. For PU systems BASF offers unfilled systems.
The Elastan® adhesion promoter for Elastopir® systems is used in the production process to improve the quality of sandwich panels with metal facings.
Our 2-component adhesion promotor type Elastan® 6541 ensures:
BASF adhesives can be used with all common process technologies. We offer highly advanced products and a complete portfolio for customers to choose the most efficient material combination running on the most suitable technology.
The rotating disc is an exclusive BASF development that represents real added value for all customers. The rotating disc guarantees an ideal material distribution of the polyurethane binder Elastan® during production, because an optimised geometry allows the polyurethane binder to be distributed particularly evenly over the entire width of the cover layer material.
In addition, the technology is aerosol-free, enables efficient material use and causes less dirt.
Our systems are currently compatible with the jetstream technology. Using this technology a targeted application jet applies the Elastan® adhesive to the facing material in an oscillating process.
Mainly used for filled systems, this technique is also suitable for specific unfilled systems. An oscillating rake or poker ensures even application of the Elastan® adhesive over the entire width of the mineral wool panels.
With Elastan®, BASF provides a high-quality polyurethane binder portfolio for a wide range of applications in outdoor flooring. Our portfolio offers versatile and tailored solutions in a variety of application areas.
Planners, architects and builders are becoming increasingly aware of the carbon footprint of building projects. In contrast to concrete, for example, wood can score points here with a significantly better climate balance. In close cooperation with the company Türmerleim, BASF has developed an adhesive line based on moisture-curing, one-component polyurethanes that is approved for the bonding of load-bearing wooden components.
The new PU adhesive line: field-tested and future-proof
The Elastan® TLP adhesive line - fully approved according to DIN EN 15425:2017 - is free of solvents, fibres and abrasive fillers.
The adhesive is offered with different reaction rates to meet customer requirements for a wide range of processing times or component sizes. The ratio of waiting time to pressing time is up to 1:1.5, at a wood moisture content of 12% and a temperature of 20°C: Thus, the PU adhesive line offers customers high flexibility and safety during processing, with optimised cycle times at the same time - and last but not least, it offers the market an alternative to already established manufacturers.
Main areas of application: Cross laminated timber, glulam timber, laminated beams and solid structural timber.
Elastan® TLP is suitable for the production of load-bearing glued laminated timber components. For example, prefabricated wall and ceiling elements can be made from cross laminated timber. The joining technology of gluing has developed into a decisive future technology in many industrial applications and thus also enables sustainable construction through the use of load-bearing glued laminated timber construction.
The trend towards more ecological construction and sustainable materials drives the demand for wood fibre insulation materials.
Our 1-component PU binder is used in the dry process for the production of stable wood fibre insulation boards. Elastan® enables excellent bonding which adds significantly to the good mechanical properties of the insulation board.
Using our binder does not influence the recyclability of the endproduct! Any production waste can be shredded and returned to the production process of wood fibre insulation boards
Tailor-made for individual needs: We support our customers in developing application-oriented solutions.
