High-Quality Polyethylene Tanks

Polyethylene tanks are a vital component of various industries. The tanks are crafted from a high-density polymer called polyethylene. This versatile material is a type of thermoplastic known for its exceptional durability and resistance to corrosive substances. Polyethylene is created through the polymerisation of ethylene, a gas derived from natural gas and crude oil.

Polyethylene tanks

During the manufacturing process, polyethylene molecules are bonded together to form a robust and resilient structure. This unique molecular arrangement provides polyethylene tanks with remarkable strength and chemical resistance, making them ideal for storing a wide range of liquids, chemicals, and even food products.

Polyethylene tanks are renowned for their lightweight nature, making transportation and installation relatively easy. Furthermore, polyethylene is resistant to rust, corrosion, and most chemicals, ensuring the integrity of the stored materials. These qualities make them a great choice for chemical storage, food processing as well as static water tanks.

Niplast Commercial Polypropylene tanks are crafted from specific gauge sheets extruded from polypropylene polymer and certain additives for example UV stabilisers. The resultant tanks boast the highest rated welding factor in the design code, reducing the risk of leaks and ensuring prolonged durability. Their high specific gravity ratings demonstrate their ability to effectively withstand the hydrostatic pressures from stored liquids.
One of the primary characteristics of polypropylene is its exceptional resistance to a wide array of chemicals, including acids, bases, effluents and slurries. Furthermore, it can also be used as a water tank material of construction.
This chemical inertness renders polypropylene tanks perfect for securely storing corrosive substances. Furthermore, polypropylene is light yet robust, making these tanks easy to handle and install while ensuring dependable performance.

Polypropylene tanks are also renowned for their high-temperature resistance, enabling them to endure various temperatures without compromising structural integrity. This attribute makes them suitable for applications where temperature fluctuations are a concern.
Moreover, polypropylene boasts UV resistance, allowing these tanks to be utilised outdoors without degradation from sunlight exposure. This resistance to ultraviolet rays ensures the tanks maintain their durability and reliability in many areas, even in tough outdoor environments. That’s why it is often the tank of choice for rainwater harvesting, in addition to storing corrosive industrial chemicals.
