What is engineering plastic?
"Engineering plastic" means "engineering plastic" and is a high-performance synthetic resin with high durability and heat resistance.
Among them, those with particularly high performance are called "super engineering plastics" and are used for industrial parts that require high functions.
Difference between normal plastic and engineering plastic
The difference between ordinary plastics (general-purpose plastics) and engineering plastics is their high functionality.
Engineering plastics also have different types and their performances differ, but generally, engineering plastics have higher mechanical strength and heat resistance than general-purpose plastics.
Although there is no strict definition, generally engineering plastics have a heat resistance temperature of 100 degrees or more, and super engineering plastics have a temperature of 150 degrees or more.
The need to produce engineering plastics dates back to around 1960.
At that time, industrial production was flourishing around the world, and the high economic growth was supported by the growth of industrial production in Japan.
In order to respond to mass production, the need to use materials that are lighter, easier to process, and cheaper than "metals" used as conventional materials has increased.
In particular, in the case of automotive parts, parts made of materials that are lighter and more durable than metals have become necessary due to problems centered on weight reduction for fuel efficiency measures in response to the problem of depletion of petroleum resources.
The development and widespread use of engineering plastics as an alternative to metal parts has further increased the need for plastic parts.
As a result, producers began to demand plastics with higher performance than conventional engineering plastics, and super engineering plastics were developed.
At present, engineering plastics and super engineering plastics are widely used as intermediate materials between general-purpose plastics and metals in terms of mechanical strength and operating temperature.
