Active Play AS H 8008 (W) is a polyether prepolymer based on an MDI isocyanate with low functionality (2.0-2.2). The product is a one-component polyurethane adhesive appearing as a clear, colorless to pale yellow liquid. It is characterized by viscosity of 2000-4000 mPas at temp. 25°C, with the content of NCO groups between 9.0-11.0%.
Active Play AS H 8008 (W) is a dedicated raw material for the production of cold and hot molded parts from SBR and EPDM rubber granules obtained also in the process of recycling.
Active Play AS H 8008 (W) is a prepolymer dedicated to bonding in various recycling processes – including the bonding of black SBR granules, also obtained from ground, used car tires. It is also used for bonding other types of shredded materials such as flexible polyurethane foams, EVA, cork and gravel.
SBR granules are obtained by cutting car tires. It is characterized by its black color, high abrasion and weather resistance. It dampens sound brilliantly, it is safe, flexible and does not absorb water. As a result, it is used mainly in the production of mats or of formed items, such as safety plates, base mats, accessories for road building and sound and vibration insulating mats.
The pigmented prepolymer - Active Play AS H 8008 (W) - must be mixed before application. The SBR granules should be moistened with prepolymer and then placed in the mold so that it is cured under the influence of temperature and moisture while the press operates.
The properties of the molded part (such as a plate) depend on the size and the composition of the rubber granules, and quantity of the one-component polyurethane adhesive and in the case of the molded process, it also depends on the degree of compression during curing. The adhesive curing process takes place at temperatures from 70°C to 150°C. The choice of temperature and humidity depends on the applied technology and allows, among other things to reduce the time of curing/polymerization.
The prepolymer, combined with SBR granules, forms a good rigid joint preserving its elasticity at the same time. It contains no harmful organic solvents.
Active Play AS H 8008 (W) is designed for the production of SBR granules, especially for the production of surface slabs for playgrounds, fitness centers, gyms and similar products made from SBR and EPDM rubber granules.
Active Play AS H 8008 (W) is a winter version of the Active Play 8008 adhesive. It is more reactive. It allows obtaining the same reactivity as Active Play AS H but at lower temperatures.
Advantages of product application:
application in various polyurethane sectors, e.g. for production of coatings, sealers, etc.
very long hardening time,
easy to apply adhesive for joining rubber granules,
broad range of application owing to a possibility to process the adhesive both in hot and cold processes,
high resistance to temperature - in production of formable elements temperatures in the range from 70°C to 150°C can be applied,
higher humidity allows shortening of the hardening process of a surface or element.
