Rubber

The recycling of materials is a process of great importance for the reduction of the environmental impact of human activity. One of the materials with the greatest problems at this level is rubber, which is why FLEXPUR decided to develop products for its agglomeration, which allow solutions with differentiated characteristics to be obtained.  

 The knowledge acquired in the field of polyurethane chemistry, the experience accumulated in the development of prepolymers and the easy access to information and innovative technical solutions, as a result of the easy contact with the main world references in this area, allowed FLEXPUR to approach the rubber agglomeration market.

In this scope, FLEXPUR offers solutions for the production of molded parts, for in-situ application in flooring installation and for granulate encapsulation and pigmentation.

Rubber bond molded parts

The agglomeration of recycled rubber can be done in mold or press with or without heating process. According to the specific conditions of the production process and depending on the desired properties of the final articles, FLEXPUR can present differentiated products in terms of:

          - Reactivity
          - Type of isocyanate - aromatic or aliphatic
          - Flexibility

We can also present tailor-made solutions and products for specific requirements of our customers, such as pigmented products or catalysts for process adjustment.

The product range considers the following references:

FLEXPUR 801MP

Standard product

FLEXPUR 805

Product with lower viscosity

FLEXPUR 850

Product with greater flexibility

Rubber Bonded Floors

One of the main applications of rubber agglomerate is as a shock absorbing material, being widely used as fall protection or sports flooring. In the application of these floors, the agglomeration is done on site, so the pre-polymer must present adequate properties to the different atmospheric conditions and to the different substrates. FLEXPUR has specific products for this application and can provide all the necessary support for their use. 

The product range considers the following references:

FLEXPUR 802

Standard product

FLEXPUR 810

Product with higher reactivity for application at low temperatures or low humidity

FLEXPUR 815

Product with lower reactivity for application in conditions of higher temperature and humidity

Pigmented granules

Another application for polyurethane prepolymers in the field of rubber granules is encapsulation for the production of pigmented granules. FLEXPUR offers products for this purpose and, due to its knowledge of the application, can provide solutions for process optimization.
