Melamine treaters for the impregnation of decorative papers (TFL – Thermally Fused Laminate) used in furniture corpuses or fronts have a long tradition at VITS.
Today we offer sophisticated systems for maximum speeds (VITS-HIGHLINE) while achieving an absolute minimum input of raw materials. The application systems designed by VITS allow a two-stage application and with this a possible top coat (melamine). The synchronous pore has also found its way into furniture surfaces. Here Vits offers special solutions for cut-to-mark and stretch control, in order to have your decor pressed according to the sheet metal structure.
Optimise your production with VITS and its partners - in terms of quality, quantity and costs. One VITS will match your production requirements from 15 to 115 million m² per year.
VITS - as most experienced pioneer and supplier - is your best partner. Our patented application systems and technologies for - mostly with melamine resin soaked - decorative or overlay papers are unique.
Beside the application systems for liquid overlay (ARP) you can apply individual quantities and sizes of corundum with the VITS-scattering devices - for all abrasion classes up to AC6. This makes you flexible and pays off.
Resin consumption measuring, web temperature measuring in the dryer or reduction of wastage by means of stretch control for synchronous pore: Your production is under control with VITS.
With VITS-lacquering lines and/or lacquering devices for finish foil production it is possible to produce high-class foil products (e.g. wall panelling and high-gloss furniture fronts), lacquered and hardened with a speed of up to 400 m/min. You can process aqueous dispersions, acid hardening or UV-coatings with plain or printed paper webs of up to 3 m width. We offer further widths upon request.
According to the requirements of your customers and their products you can manufacture in a one-stage or two-stage process. VITS-coaters can also be integrated into other types of lines to allow greater product flexibility and mixed production (melamine films, finish foil).
For final products, such as window sills, work tops, or laboratory surfaces, VITS offers tailor-made solutions for phenolic or melamine paper impregnation to you. Our corundum application units or scattering devices will increase the abrasion resistance of your products.
We also possess the required know-how in additives and resins to be able to produce modified papers for the required post forming (post and soft forming).
With their wide spectrum of colours and surface qualities they are in line with the trend:
Architects and designers create modern exterior facades and interiors with compact boards, with special requirements, such as moisture resistance and increased fire resistance.
For the impregnation of core papers with phenolic resin VITS has developed bespoke solutions on our own pilot plant. Water-soluble and solvent-containing resins, bio-degradable and with different solid contents as well as recycled papers can be processed equally. A solvent concentration monitoring ensures safety and utilisation of possible line speeds.
The reliable VITS-cross-cutter system allows running maximum line capacities. Production of phenolic core papers roll-to-roll is possible for speeds up to 300 m/min. Paper dedusting, online measuring of temperature, coating weight and final moisture content enable a secure and reliable production. Optionally we supply resin preparation systems and exhaust air purification.
Technical laminates in our area are made of so-called Prepregs (English short for pre-impregnated fibres). In a pressing or calendering process several layers of the prepregs are melted together and hardened, in order to reach different technical characteristics. Objective is the creation of a structure as homogeneous as possible, to guarantee highest technical standards. These are - amongst others - electrical and thermal conductivity in the semiconductor and electro industry, power transmission in any form in the motor production as well as special gliding qualities in the area of bearing technology.
Advantage in the production of prepregs with a VITS-impregnation line is the even saturation of the carrier material, e.g. glass fabric, carbon fibre, paper or cotton with special epoxide or phenolic resin mixtures. Furthermore we offer sophisticated drying technology, which - with lowest energetic input - evaporates the solvents and executes the chemical drying or hardening process to the point.
VITS has got extensive and versatile expert knowledge in the area of filter paper plants, e.g. for the automobile industry. The oil filters used here consist mostly of papers impregnated with phenolic resin. Our plants are outlaid and configured according to client-specific parameters, as web width and speed.
Adhesive tape is a collective name for one-sided or two-sided strip-shaped coated carrier materials, e.g. made of plastic film and/or plastic foam, paper, metal foils or textile fabric. In the industrial production also so-called transfer tapes are used: carrier-free, thin pressure-sensitive adhesive films, which are covered with waxed or siliconized protection paper before they are processed. Adhesive tapes can, with printing and punching, also be processed to self-adhesive labels in web form.
They are used as consumption items in many different industries, e.g. construction, automobile industry or for painting and maintenance works. It is differentiated between duct tape, gaffer and masking tape.
Masking tape in particular is used for masking of window and door frames or other items to protect them against undesired contact with colour. It is made of cellulose and adhesive, and is available in width from 12 to 75 mm. The roll length in general is approx. 50 m.
Concrete shuttering films are thin, low-cost craft papers saturated with a phenolic resin solution in a one-step impregnation process. In the next production stage the finished papers are pressed under high pressure and temperature to the carrier plate to be a covering layer. With this the laminated plate is water-resistant and does not stick to the concrete wall. The modification of the resins by means of additives enlarges the utilizability of the papers for different uses. On the same plant also HPL- and CPL-papers can be produced. These are, together with a melamine-soaked decorative paper layer, pressed to a covering layer.
Typical end products:
Web-shaped glass fabric or glass non-woven will be penetrated with a resin solution in a one-stage or two-stage process. If required, also a coat with an adhesive or a separating agent can be done. Then the webs are laminated to the carrier material, in order to fulfil the required properties, such as fire resistance or moisture-proofing. Therefore they are – amongst others - used as carrier material for thermal insulation boards, either as typical end product for the building and insulating material industry, or for the press and injection moulding tools in the electro industry.
Mica is a mineral material with extreme low electrical conductivity and heat resistance up to 600 °C. In thin slate slices mica is brought to a web-shaped composite - similar to paper manufacture - and rewound.
The mica web, in its unprocessed condition sensible and hard to handle, serves e.g. in the form of sandwich foils or multi-layer pressed compacts as isolator in the semi-conduct and electro industry. Due to the long-time experience in the area of coating and drying of sensible web materials, VITS is one of the sparse specialists for plants for the production of multi-layer mica foils and/or mica paper.
