Polypropylene is one of the most commonly used plastics in the world. In fact, its volume is second only to polyethylene. Although polypropylene is such a commonly used material, it is still important for engineers and entrepreneurs to understand polypropylene plastics: its performance, its use, and even its history. In addition to being widely found in the production of Pet Preform Mould, polypropylene is also well suited for prototyping. Learn more about the material to help you understand why.
Some background of polypropylene
For this ubiquitous material in manufacturing and packaging, polypropylene is relatively „young“ – it was first synthesized in 1951. However, its popularity may be referred to as „meteorological growth“, reaching the current global demand level of 55 million tons (based on recent available estimates). Surprisingly, this demand is expected to continue to grow and is expected to grow by 5.8% by at least 2021. To date, the use of polypropylene has not shown any signs of stagnation.
Polypropylene performance
Why is the popularity of polypropylene growing, continuing, or even continuing to grow? Its material properties make it very useful in a wide range of applications. Injection molding is very easy due to good viscosity. It is highly resistant to most other materials such as acids or bases and is therefore well suited for a wide range of consumer and industrial uses. It exhibits a high level of material strength even in very thin gauge applications. As a thermoplastic material (as opposed to thermoset materials), this proves to be very cost effective because the excess or waste material can be reheated and recycled.
Polypropylene use
As noted above, these polypropylene properties give the material a wide range of uses. The most common case is that you will find polypropylene for the production of China Pet Bottle, whether it is a plastic „shell“ for the product or a film plastic. Especially for those extremely thin films, the high material and tensile strength of polypropylene make it very suitable. Due to its versatility, polypropylene is also used in electronic components, automotive components, electrical and architectural applications. Another area where polypropylene brings benefits is prototyping, which has proven to be very useful for short-term injection molding and even CNC machining.
