Spray Waxes

The company, located in Castelli Calepio (Bergamo - Lombardy - Italy), has made the brand-name Maplus a synonym of scientific research, innovation and performance in the field of winter sports. The five-year experience next to the most important Federations in the world, together with an interesting scientific research activity, leaded by Prof. Gian Paolo Gambaretto, have allowed formulating a new range of spray liquid ski waxes (gas free), with high melting point and very high performance.

The reasons that have prompted Maplus to follow the way of innovation are several and based on strict scientific principles:

  1. The use of ski waxes with high melting point and specific characteristics of low friction coefficient and high resistance to abrasion implies the achievement of critical temperatures (160 C and higher) for the internal ski structure, polyethylene and waxes themselves. This has also a negative effect on human health, due to sublimation and consequent inhalation of a part of fluoridised components from paraffin and waxes.

  2. Inspections carried out on insoles with the most recent analysis techniques, such as:

    • FTIR - Infrared spectroscopy in Fourier's transformation;
    • DSC - Differential scanning calorimetry;
    • SEM - Electronic scanning microscopy;
    • ESCA - Photoelectronic spectroscopy;


    have shown that ski wax penetrates into polyethylene micro-pores for a maximum depth of approximately 20-25 micron. They have confirmed the principle of chemical inertia of insoles, reinforcing the theory that the so-called "greasing" does not exist.

  3. Ski wax penetrates thanks to a pressure mechanic action until full saturation; the best absorption of ski wax is in liquid form; therefore, for the best application, the difference does not depend on hot application, but on the physical conditions of wax, that should necessarily be in liquid form.

  4. The inspection of insole samples, duly treated with high-melting-point products, on an electronic microscope has revealed the even distribution of spray liquid wax applied in cold conditions, in comparison with the same product applied in hot conditions. This presents an uneven surface, deteriorated by product shrinkage due to cold crystallisation and micro-movements of polyethylene subject to a thermal shock.

  5. The precision weigh of insole samples treated with the same product in spray liquid and solid form with thermal melting has shown that, in the worst hypothesis, cold treatment with spray increases the quantity of wax in the insole by 20% in comparison with hot application - and in the best hypothesis by 79% (with perfluoridised waxes).

Scientific research of recent years into base materials and liquid ski wax products, conducted especially by the University of Padua, has given prominence to a few particularly sophisticated processes capable of respecting the structure of the materials in question, in accordance with the scientific principles below:

  1. The liquid developed by Maplus and used to remove perfluoroparaffin spray ("WAXES") from the bases are totally harmless for the polyethylene bases of the skis. This is true for both polyethylene of medium molecular weight (widely used) and even more so for polyethylene of high to very high molecular weight (high level and competition skis).

  2. Furthermore,such liquids cannot dissolve the hydrogenated paraffins that form normal ski waxes (widely used), as they are completely non-mixable with these.

  3. The above statements are confirmed not just by experience in the laboratory, but also by the widely available scientific literature that can be consulted on the subject.

  4. A further scientific reason that is easy to understand, and which proves the above, is the following: the so-called "normal" ski waxes (those traditionally distributed on the market by all manufacturers) can, in almost every case, be considered to be polythenes with extremely low molecular weight. In practice, these belong to the same family as the ski bases that, as is well known, are made from a polythene of a higher molecular weight. Since the liquids mentioned above cannot dissolve these paraffins, all the more reason they cannot dissolve polythenes of medium, high and very high molecular weight or interact with these in any way.
    Purely by way of example, it should be remembered that the paraffins on the market have a molecular weight of up to max. 600-700, while ski bases have molecular weights that vary between 500,000 and over 6 million (in the case of racing bases).

  5. The same can be said for liquid Maplus products, the components of which exactly reflect the same chemical and physical characteristics mentioned above.
