Özet
In this work, rigid foams designed and manufactured using the freezedrying technique were made from polyvinyl acetate (PVAc), bleachedkraft pulp and unbleached kraft pulp. The rigid foams designed asan environmentally-friendly product with no pentane or hydrochlorofluorocarbon included in the manufacturing process. The PVAcbased foams were reinforced with different kraft pulp contents. Theirperformance properties such as compressive and flexural strength,physical and morphological properties were investigated according torelevant standards. The foam densities ranged from 0,017 g/cm3 with%17,65 coefficient of variation (CV) to 0,137 g/cm3 with %2,33 CV.The compression resistance was found between 0,001 N/mm2 with%50,00 CV and 0,03 N/mm2 with %5,98 CV. The flexural resistancewas found between 0,005 N/mm2 with %20,00 CV and 0,11 N/mm2with %6,06 CV. Optimum properties were observed at B-4 (PVAc/Bleached Kraft pulp 1/0.8). Bleached kraft pulp reinforcement gavebetter results on performance characteristics of foam materials compared to unbleached kraft pulp reinforcement. Overall test resultsshowed that the PVAc based rigid foams have promising results.
