What sounds promising and complicated at the same time actually is absolutely easy / and therefore patented.

The peculiarity about Spheretex GmbH products is the combination of light hollow microspheres with high-modulus fibres. The production process is generally the same with all products. Thermoplastic microspheres are embedded into high-modulus fibres in their unexpanded stage by means of a watery suspension in such a way as to evenly distribute the respective particles between the elementary fibre strands right to their interior.

The following thermal process causes these unexpanded filler material particles to expand. In doing so the elementary fibres brace each other and volumise the fibre strands in definable way up to x times their original volume.

The so created products exhibit a material thickness between 1 and 12 millimetres. These material thicknesses can be freely adjusted through the composition of the base materials, amount and quality of the thermoplastic microspheres and through the production parameters. At the same time the mechanical properties can be arranged to suit the desired field of application by means of the quality of the high-modulus fibres and, through high or low fibre ratio.

Take a look at the animation to see the entire procedure in detail.

The weight characteristics and the resin absorption can also be modified depending on the product by means of a higher or lower concentration of microspheres. Furthermore, the products can be adjusted to the various processing technologies through different material structures and microsphere quality.
