Disadvantages of Unplasticized Polyvinyl Chloride (uPVC)

Poor Heat Insulator

The poor heat insulation property of uPVC makes it unsuitable when high insulation levels are required. Since the material lacks insulative properties, large amounts of heat can easily transfer from one area to another through uPVC with minimal resistance. This property of uPVC can even result in significant energy losses and lead to a significant increase in energy costs for owners.

Therefore it is highly recommended to use other insulative materials, such as natural wood, in situations that require good insulative capability. Natural wood can be used for doors, windows, profiles, and so on, offering superior insulation levels and aesthetics. However, cost implications must be considered when buying and using natural wood.

Traps Moisture

Unlike other types of plastic and vinyl, uPVC does not allow water vapor, or moisture, to escape. As a result, if moisture or condensation builds up within the material, it can cause some problems, including mold growth, pests, and corrosion.

To reduce the risk of these issues, one of the most important things to do when installing uPVC is to ensure that no moisture can become trapped within the material.

This can be achieved through appropriate design (such as not putting uPVC in enclosed areas), good maintenance (regularly painting and sealing the material to help prevent water penetration), and proper ventilation (using vents, exhaust fans, and windows to help ventilate the area). Unfortunately, water vapor can still become trapped within the uPVC even with these steps.

To help reduce this risk, some manufacturers have developed a type of unplasticized PVC that is more breathable. This allows the water vapor to escape, which minimizes the risk of moisture problems.

Not Suitable for Recycling

Unfortunately, uPVC has several disadvantages, including being unsuitable for recycling. uPVC is composed of two types of molecules, one stronger and more brittle, the other weaker and more flexible. When it is melted down into a form, these molecules separate, making it difficult to re-mold and shape the material into new products.

In addition, recycling uPVC requires specialized equipment, which is costly and energy-consuming. This makes it more expensive and less efficient than recycling other plastic materials.

Furthermore, not all types of uPVC can be recycled, such as the thick and rigid PVC used in windows or pipes. Additionally, recycled plastic usually has different properties than the original material, so it is unsuitable for some applications.

uPVC is unsuitable for recycling due to its complex chemical makeup and requires specialized equipment and processes, making it more expensive and less efficient than other forms of plastic. Therefore, it is important to find alternative uses for uPVC or to avoid using this plastic in applications if possible.

Susceptible to UV Damage

It is susceptible to damage caused by ultraviolet (UV) light, which can cause discoloration, cracking, and other issues. UPVC windows, when exposed to sunlight, can gradually take on an oxygenated yellow color, and frames can form visible fractures and become brittle and flaky.

UV radiation also attacks the inner layers of UPVC, leading to tiny cracks that weaken the material and cause leaks. The damage worsens with increased exposure to sunlight, causing further leaks and weakening the material further.

Manufacturing Processes for Unplasticized Polyvinyl Chloride

Background

Unplasticized Polyvinyl Chloride (uPVC) is a strong, rigid, and ductile thermoplastic material with excellent chemical and weather resistance. It is popularly used for framing, window and door frames, siding, conduits, signs, and pipes in construction industries.

Unlike traditional PVC, uPVC does not contain plasticizers and comes ready to use after simple processing. Because of its rigid nature, uPVC must go through processes such as extrusion and injection molding to be ready for use.

Extrusion

Extrusion is the most popular process used to produce uPVC. The process involves using a die to cross-sect the material to make it into a desired shape. In extrusion, the required uPVC material is heated to a semi-molten state and then forced through a specially designed die.

During this process, the uPVC gains its rigid shape.

When the die is compressed, two sets of cutting blades provide the material with its desired shape. The added pressure of the blades creates ridges, also known as 'legs,' on the inner side of the extruded material. This process results in increased rigidity and strength of the uPVC product.

Injection Molding

Injection molding is the most widely used technique for producing uPVC components. First, the required raw material is melted before being injected into a mold. This process is repeated with different materials and colors to create the desired uPVC end product.

After the material is injected, the mold is cooled, and the end product is removed. Injection molding allows for the production of complex shapes or designs that cannot be achieved using extrusion.

Safety Considerations for Unplasticized Polyvinyl Chloride

Unplasticized polyvinyl chloride (uPVC) is a versatile plastic material commonly used in various pipes and fittings, window frames, and other products in the construction industry. It is an attractive choice due to its low cost, low maintenance, and ability to resist corrosion and chemicals.

However, uPVC can present some safety risks, and workers handling the material should take extra precautions to ensure their safety. When machined, uPVC produces fine particles, referred to as dust, which can be hazardous to workers in the area. When inhaled, the particles can irritate the skin and eyes and damage the respiratory system.

To reduce workers' exposure to dust, it is important to utilize appropriate ventilation, such as localized air cleaners, in the work area when cutting, drilling, or otherwise machining the material.

Workers should also wear appropriate safety equipment, such as dust masks and safety glasses when handling uPVC. When burning uPVC, it will release toxic smoke and gases, including toxic hydrochloride compounds and potentially carcinogenic dioxins.

Exposure to these substances can cause severe respiratory irritation, coughing, and difficulty breathing. All uPVC products should be labelled as non-combustible, and workers should use caution when working near the material to reduce the potential for harm.

Workers should also be aware of the potential for static build-up when handling uPVC. This static electricity can build up easily and cause sparks that ignite nearby flammable material. Workers should wear protective clothing and grounded wrist straps to prevent static build-up.

Contact with uPVC can cause skin and eye irritation, so it is recommended that workers wear appropriate protective clothing and gloves to minimize their risk of contact with the material.
