Thermally Insulating Polymers and Plastic Resins
Polymers and plastic resins are compounds consisting of repeating subunits of organic or synthetic base molecules. Polymers describe a material at the macromolecular level, while plastic resins describe the material in bulk form. These compounds are commonly used as raw materials in plastic molding applications.
Thermally insulating polymers and resins are compounds that are engineered to minimize or reduce the heat transfer between objects in thermal contact or in a range of radiative influence. Like regular polymers, thermally insulating polymers are formed via the polymerization of two or more organic monomer molecules. However, thermally insulating polymers and plastic resins have a slightly different structure. These compounds have a reduced intermolecular bond path length and reduced density, thereby causing low thermal conductivity.
Thermally insulating polymers and plastic resins have a larger molecular mass relative to small molecule compounds. This attribute gives them some desirable properties, such as toughness, viscoelasticity and high elasticity.
Specifications
- Thermal conductivity describes the ability of a material to conduct heat. It can be defined as the rate at which heat can be conducted through a unit cross-section area of the polymer or plastic resin.
- Tensile strength describes the ability of a material to resist a force when being stretched. It is defined as the maximum amount of stress required to break the polymer or plastic resin component under tension loading test. It is also known as ultimate tensile strength (UTS)
- Use temperature describes the range of temperatures for which the material is designed to operate normally. Exceeding the specified use temperature can cause degradation of structural or other end-use properties of the polymer.
- Melt flow index (MFI) is the measure of the ease of flow of melted plastics. It is an important parameter for quality control in plastic industries.
- Tensile modulus is a measure of the polymer’s resistance to elastic deformation.
Applications
Thermally insulated polymers and plastic resins have a wide variety of applications in different industries. Because of their toughness and thermal insulating property, these polymers are commonly used as adhesives in aerospace and building construction applications. Other common applications include semiconductor packaging, optoelectronics and plastic molding.
