One of the most important choices you’ll have to make when picking a washing machine is whether to get a plastic or stainless steel drum. Each material has benefits and cons of its own that can affect how well and how long your washing machine works. Making an informed decision that meets your needs and preferences will be made easier for you if you are aware of these differences.
Tanks made of plastic are renowned for being inexpensive and rust-resistant. They are a popular option for many homes since they are frequently lighter and sometimes less expensive. On the other hand, plastic might not hold up as well over time, particularly if it is subjected to severe environments or heavy use.
Conversely, the strength and longevity of stainless steel drums are highly regarded. They are less vulnerable to damage from the heat and moisture inside the drum and can withstand higher spin speeds. For many users, their superior performance and longer lifespan make up for their higher price.
This guide will take you through the important things to think about when deciding between a washing machine drum made of plastic and one made of stainless steel. To assist you in choosing the solution that best suits your washing needs and price range, we’ll break down the advantages and disadvantages of each material.
| Feature | Plastic Tank | Stainless Steel Tank |
| Durability | Less durable, prone to wear over time | Highly durable, resistant to rust and corrosion |
| Noise Level | Quieter during operation | Can be noisier due to vibrations |
| Heat Retention | Lower heat retention | Better at retaining heat |
| Weight | Lighter, easier to move | Heavier, more stable |
| Cost | Generally more affordable | More expensive |
| Maintenance | Less likely to rust | Requires regular cleaning to prevent rust |

What is Polynox?
Polinox is simply polypropylene with specific chemical additives given a more appealing name rather than a completely new substance. The production of washing machine tanks uses it. For many reasons, polinox tanks are highly common. First off, the low cost of this material lowers the price of washing machines. Second, processing it is not too difficult. Thirdly, stainless steel tanks lack some of the qualities of Polynox tanks.
Take note: Polinox is less expensive than stainless steel. Its tanks are less expensive when used in washing machines.
Polinox and additional plastic alternatives
Bosch washing machines frequently use Polinox. However, analogs of this material are also used by other manufacturers. Polyplex is the analog that is most in use. It is unafraid of rust, high vibration, and other metal drawbacks. However, in contrast to other plastic analogs, it is still brittle.
Tanks from Electrolux are made of Carborane, a more costly and more durable plastic, which is reflected in their price. The company’s own development is carborane. Electrolux improved the strength of their plastic while also making sure that it has improved sound, thermal, and odor absorption properties. Furthermore, Carborane has no fear of harsh chemicals.
Candy likes to use Silitek, which is basically a full equivalent of Polinox with a few small variations. Environments that are alkaline or acidic do not frighten it.
Benefits and drawbacks of Polinox tanks
Producers started making plastic washing machine tanks in an effort to lower the cost of the machines. Customers are pleased with the price reduction on the one hand, but they are skeptical of the tanks’ dependability and durability on the other. First, let’s examine the apparent benefits of plastic tanks:
- Plastic tanks are less susceptible to vibration during washing. This reduces the noise level of the washing machine.
- Polinox tanks retain heat better inside, that is, the water does not need to be constantly heated. This reduces the energy costs of the washing machine for heating water.
- Plastic is significantly lighter than metal, which reduces the weight of the washing machine. This makes it easier to transport.
- Polinox will not be damaged by moisture and will not rust. This increases its service life.
- As mentioned above, Polynox is cheaper than stainless steel. Machines with plastic tanks are cheaper than their counterparts with metal ones.
While there are numerous benefits, there are drawbacks as well:
- Plastic is easier to damage. Therefore, if a stainless steel tank can withstand impacts from hard foreign objects that get into the tank along with your clothes during washing, then Polinox may crack with another impact at high speeds.
Crucial! Take extra care to inspect the plastic tank if your washing machine has one. Sharp, hard fittings can cause damage to it!
- In addition, during self-repair or coastal transportation, plastic tanks can also be damaged by impacts.
However, producers are aware of this drawback and have improved the plastic’s recipe. More robust plastic is being used in modern washing machines than in their more recent predecessors.
It’s important to consider the advantages and disadvantages of both materials when choosing a washing machine tank—plastic or stainless steel—to determine which best suits your needs. Although plastic tanks are more cost-effective and rust-resistant, they may not be as long-lasting as stainless steel tanks, which provide longer lifespans and higher efficiency over time. This guide will examine the main variations to assist you in selecting the best washing machine configuration.
For your washing machine, the decision between a plastic and a stainless steel tank ultimately boils down to your personal requirements and tastes. For people who value cost and ease of maintenance, plastic tanks are a sensible choice because they are usually lighter and more rust-resistant. However, because of their strength and resistance to wear, stainless steel tanks are well-known for their long-term performance and durability, which frequently justifies their higher price.
When choosing, take your household’s laundry routine and spending limit into account. Plastic tanks are a good option if you’re searching for an affordable solution that works well. Nevertheless, spending money on a stainless steel tank might be the best course of action if you want a device that will withstand the test of time and manage big loads without any problems.
Ultimately, each choice has advantages. You can choose the option that best fits your lifestyle and guarantees you get the most out of your washing machine for years to come by weighing the advantages of each and being aware of your particular washing needs.
