While scrolling through my research notes, I came across some interesting insights about plastic materials. Plastics can be broadly categorized into two main types based on their molecular structure: thermoplastics and thermosetting plastics. Thermoplastics are those that can be melted and reshaped multiple times when heated. Common examples include PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), PS (polystyrene), ABS (acrylonitrile butadiene styrene), PMMA (polymethyl methacrylate), POM (polyoxymethylene), PC (polycarbonate), and PA (nylon). These are widely used in everyday applications due to their versatility.
On the other hand, thermosetting plastics are made from resins that harden permanently once cured by heat. While they're less common, they’re still important in specific industries. Examples include certain phenolic plastics and amino plastics, which are known for their durability but aren’t typically found in consumer products.
When it comes to practical use, plastics can also be grouped according to their applications. General-purpose plastics like PE, PP, PVC, and PS are widely used for packaging and household items. Engineering plastics such as ABS, POM, PC, and PA are more robust and often employed in industrial or automotive components where strength and performance are critical. Additionally, there are specialty plastics designed for unique environments, such as high-temperature resistance, moisture tolerance, or chemical corrosion resistance. Some plastics are even modified for very specific purposes, making them ideal for niche applications.
As I think about all these different types, it’s fascinating how each material is tailored to meet particular needs. Whether it’s something simple like wrapping food or something complex like building an airplane part, plastics play a crucial role in modern life. It just goes to show how diverse and essential this material really is.

The liquid inlet/outlet adopts a ceramic hard seal structure, the liquid is in contact with the ceramic throughout the entire process, and does not touch the stainless steel jacket. The ceramic parts of the liquid inlet/outlet can be disassembled for cleaning and disinfection like the ceramic plunger rod and the ceramic reversing rod, which completely solves the problem of cleaning the dead angle between the steel jacket and the ceramic.
