Engineering and High Performance Plastics 

ENERGETIC PLASTICS is mainly focusing on engineering and high performance plastics. As such it is essential to gives you an overview of engineering and high performance thermoplastics, their key properties and applications. Engineering plastics/polymers represent a group of plastics that possess a range of desirable performance properties than standard commodity thermoplastics. They normally offer following advantages that enable them to be excellent alternatives to many conventional materials such metals and ceramics.
Some Properties of Engineering plastics:
-          Good mechanical strength, impact resistance and rigidity
-          Resistant to many chemicals
-          Good wear and abrasion resistance, self-lubrication 
-          Excellent machining and processing properties
-          Good dimensional stability
There is no clear definition of a high-performance plastic. There is inevitably an overlap between high performance plastics and general engineering plastics. Some commodity plastics can also be modified through reinforcements to compete with engineering resins. As a general rule of thumb however, high performance plastics are considered to have a short-term heat resistance of 250 °C and long-term heat resistance of 160 °C. Other distinguishing features of high performance plastics include their high strength and stiffness, resistance to many chemicals and their outstanding electrical properties.
