Abstract

The polyurethane Sealant (TRITOSIL H10 PU) mechanical and combustion characteristics were examined in this study as a function of the weight ratio of tire rubber powder (waste), with a particle volume of (150 μm). Elongation, tensile strength, Young's modulus, compressive strength, and rate of burning time were a few of the characteristics examined. The results showed that adding filler decreases the spaces between the chains of polymer, reflecting the polymer's high ability to withstand the stress imposed on it, that the degree of homogeneity between each of the fillers and polymers is high, and that increasing the percentage of fillers gives the prepared models a slight increase in hardness at a percentage increase (25%). Based on research into combustion resistance, The results of the experiments showed that increasing the amount of used filler has a positive impact on heat diffusion through the polymeric matrix and flame resistance. The use of filler as a filler has an impact on the properties of the polyurethane polymer, which has high mechanical properties. This increases tensile strength, which makes it appropriate to cover the flooring of indoor playgrounds, kids' playrooms, and other spaces.
