Electrical Properties of Rigid Pour Polyurethane Foam Applied for High Voltage Insulation
Proceedings of the IEEE Power Engineering Society Transmission and Distribution Conference, 2003Co-Authors: George G. Karady, Baozhuang Shi, Mehmet Argin, F. Rahmatian, Allen H. RoseAbstract:Rigid pour Polyurethane Foam is presented to serve as a high voltage insulation material. The proposed Foam is closed-cell two components flotation system that has low viscosity and low pressure. Different production techniques are applied and explained. The investigation of cross-section and skin of rigid pour Polyurethane Foam is performed with SEM (Scanning Electron Microscopy). The electrical properties are studied under power frequency and lightning impulse voltage. The effects of water and Foam skin on its properties are also investigated.

New Sound Absorbing Materials Obtained from Waste Rigid Polyurethane Foam
Materiale Plastice, 2019Co-Authors: Ancuta Elena Tiuc, Ovidiu Nemes, Horaţiu Vermeşan, Daniela Roxana Tamas Gavrea, Ovidiu VasileAbstract:Polyurethane Foam wastes is one of the environmental problems for which are not still the efficient solutions of valorization. This paper presents the possibility of recovering Polyurethane Foam waste by obtaining some new materials with sound absorption properties. The Polyurethane Foam wastes were ground and mixed, in proportion of 0, 3, 5, 7 and 12 wt%, with bicomponent Polyurethane Foam as a binder, resulting 5 new materials. The sound-absorbing properties of the new materials have been determined and it can be observed that the sound-absorbing properties of rigid Polyurethane Foam with closed pores can be improved by adding Polyurethane Foam waste to its structure. In addition, the mechanical properties and thermal conductivity of the new materials were studied.

improved sound absorption properties of Polyurethane Foam mixed with textile waste
Energy Procedia, 2016Co-Authors: A E Tiuc, Horaţiu Vermeşan, Timea Gabor, Ovidiu VasileAbstract:Abstract Polyurethane Foam is an outstanding material for various applications. It is manufactured by propelling liquid isocyanate-polyol mixture to form Foams in the presence of a blowing agent. This paper comprises an experimental study on acoustic properties improvement of rigid Polyurethane closed-cell Foam, by incorporating various quantities of textile waste into the matrix. In order to obtain a homogenous, easy to handle material, an optimal percent of 10-50% textile waste was used. The sound absorption coefficient of the composite materials was measured using an impedance tube. The composite materials obtained have better sound absorption properties compared to rigid Polyurethane Foam. The noise reduction coefficient (NRC) of the composite material with 40% textile waste and 60% rigid Polyurethane Foam is twice as high as the 100% rigid Polyurethane material.
