Investigation on the use of Coco Coir Polypropylene as Thermal Insulator Tomas U. Ganiron Jr College of Architecture, Qassim University, Buraidah City FADHLAN RAMADHAN ALWINAS D3 TEKNIK ELEKTRO,fakultas Teknik,universitas riau Bahan-Bahan Listrik Abstract Thermal insulators are essential in terms of making structures conducive for people to live in and a nice place to work on. This experimental study aimed to develop a thermal insulator using recyclable materials namely; the coco coir from the coconut fruit and used polypropylene drinking straws. This lead to the assumption that all materials have a property to conduct heat and a material which has low thermal conductivity is an ideal insulator. Observing the physical properties of the coco coir being a composite material and various applications, It was incorporated, as well as the polypropylene used straws being commonly named as plastics gives an idea to make these materials the core components of a product that can be used as a thermal insulator. 1. Introduction These days, people who have means to spend, would like to lead a luxurious and comfortable life. For this, the designing and construction of some of the residential and important public building is done in such a manner that they are least effected by heat, cold sound or electricity. By doing so, the efficiency of doing work also increases. All those materials which minimize or check the passage of heat, cold, electricity or sound through them are

called insulators or insulating materials. Some of them are successful only to check the transfer of heat, when they are known as heat insulating materials. Others may be useful to block the transmission and reflection of sound, when they are known as sound or acoustic insulators, while still others may be useful as electrical insulators. To achieve these insulating effects, it is essential to either use insulating materials or device special methods of construction or as an alternative use both. Difference of temperature between outside, inside or between the different parts of the building will result in a transfer of heat from hotter or coolest areas. Heat or cold is transmitted through conduction, radiation and convection. In buildings, the transfer of heat through solid materials takes place, mostly by conduction. The materials used to check the transfer of heat are known as heat insulators or thermal insulators. These insulators act as a barriers or at least retards the passage of heat. The common materials which are used as heat, insulating materials are cork, quilt, rock wood, loose fills, blanket insulation, aluminum sheets, boards, reflecting appearance and light weight aggregate. Research are made for the development of a new product that possess low heat conductivity, stable chemically, physically and mechanically at high temperature, insulators, while still others may be useful as electrical insulators.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
