Polystyrene (PS) is a clear, rigid plastic used for lab bottles and cutlery
Polystyrene (PS) is a synthetic polymer made from the monomer styrene, an aromatic hydrocarbon. It is a clear, rigid, and inexpensive plastic with a low melting point. Polystyrene is naturally transparent, but it can be coloured with colourants for various purposes. It is lightweight, durable, and has incredible dimensional stability, which means it can withstand stress and remain consistent in size and shape despite external conditions. However, it has low impact strength and fair chemical resistance.
Polystyrene is used in a wide range of applications due to its desirable properties. It is commonly used for producing disposable plastic products such as cutlery, containers, bottles, and laboratory equipment like Petri dishes, test tubes, and microplates. It is also used in packaging, with its most significant use being foam packaging. Polystyrene is further used in automotive and electrical components, electronics, and optics.
In terms of its production, polystyrene is one of the most widely used plastics, with several million tonnes produced annually. It is often manufactured in pellet form through a process of extrusion, where it is pushed through a heated tube and cut. Polystyrene can be a thermoplastic or thermoset material, depending on its polymeric arrangement. Thermoplastics can be melted and reused, while thermosets cannot be remelted after initial forming.
Polystyrene has some disadvantages, including its slow biodegradation, which has led to concerns about its environmental impact, particularly regarding its use in disposable packaging. It is also naturally brittle, and while this can be improved through copolymerization with more flexible materials, it remains an inherent property. Despite these drawbacks, polystyrene's unique properties make it a popular choice for a variety of applications, especially in the creation of clear, rigid products like lab bottles and cutlery.

High-Density Polyethylene (HDPE) is durable and chemically resistant
High-Density Polyethylene (HDPE) is a commonly used thermoplastic polymer produced from the monomer ethylene. It is also known as polyethylene high-density (PEHD) or alkathene/polythene when used for HDPE pipes. HDPE has a high strength-to-density ratio, making it a durable and chemically resistant material. This durability is due to its linear structure with few branches, which gives it optimal strength and density.
The molecular makeup of HDPE makes it resistant to moisture, chemicals, and UV rays. It is also exceptionally challenging to glue, with joints typically made by welding. HDPE is commonly used in the chemical, automotive, food, and pharmaceutical industries for containers, bottles, and IBC totes. It is often used for blow-molding applications, especially in food and beverage containers, as it won't leach into the contents.
