What is white uPVC profiles and Why Do We Use Them?

Heat Preservation and Insulation. It is widely known that plastic material get a lower heat conduction rate in contrast to metal materials. That means windows or doors made with UPVC profiles can get more heat reserved and reduce energy loss inside a house where the temperature is low outside. However, under a surrounding where it's hot outside,it can stop more heat going into rooms to keep it cool enough.

Noise Reduction. Noise pollution is an important issue that people across the world are concerned about nowadays. There is a exclusive and special design on cavity for insulating and decreasing noise around us.

Economic Costs. When a window or door get appromximate costs on glass and hardware, the difference of price will be up to window frame. UPVC windows or doors are cheaper due to its materials at low costs compared with others.That is what we say "cost performance".

Various Options on Appearance. According to customers' different requirements on appearance, custom colors are available for options. It provides more choices to match with buildings.

UV-resistance & Anti-aging. By adding anti-ultraviolet agent into product formula that contains various kinds of materials,windows or doors made with this uPVC profiles even those on regular white color show great  performance on blocking UV and are kept refrained from fading away after a long-period using and exposure in the intensive and straight sunlight.

ECO-friendly. All materials are lead-free and comply with standard of Rohs. 

Guarantee by Qualified Certificates. Meeting standards of CE and ISO, materials and finished products are both under severe tests and quality checking before delivery and shipments.

White Profiles-- Windows made of white uPVC profiles are commonly used in all kinds of buildings. According to climites in differernt regions, this white uPVC profile has a good performance on anti-uv and anti-aging.

Homogenous Profiles--The whole body of this window frames are same color.The stability is good enough during it working period.

Profiles with Laminated foil--Laminated with foils on the surface, the window looks very nice.In order to meeting many different requirements for both apperance and performance, we provide customers with uPVC profile with laminated film which includes wooden grain,walnut,smoky gray,golden oak,brown,etc. In addition to that, this craft get the function of anti-UV and weather resistance improved to a higher level.This makes it to be a high-end series and well welcomed by customers.

Co-extruded Profiles--The windows only get colors on both visible sides. Compared with homogenous type, it spends less and has great properties as well.

In this blog we will introduce you to the meaning of the term uPVC, the benefits of using it, the type of uPVC we use to manufacture rigid plastic extrusions, the type of uPVC which is used for other types of products, and how PVC is made flexible.

Introduction to uPVC

The term uPVC is an abbreviation for the full phrase which is ‘Unplasticised Polyvinyl Chloride.’ The 'u' in 'uPVC' stands for unplasticised which means it does not have added plasticisers and so it retains rigidity. It can be described as being rigid (like a ruler) rather than flexible (like a belt).

This type of plastic material has advantages over alternatives such as wood or aluminium. Some benefits of using uPVC include:

• Low maintenance
• Longer lasting
• Can often be used outside as well as inside
• Energy efficient
• Recyclable
• Easy to clean

uPVC is supplied to manufacturers as compound, which looks like small round pellets which you can see in the above image. When processing these pellets care should be taken to minimise spills and to clear them up promptly on occasions when spillages occur.
Many sectors use uPVC widely including extrusions, mouldings, double glazing, windows, doors, plumbing, drainage and building materials.

The type of uPVC used to manufacture rigid plastic extrusions

uPVC is often used in the manufacture of plastic profiles. All uPVC is stabilised, and here at MKM Extrusions we use an external grade of uPVC which makes our rigid extruded profiles suitable for outdoor applications.

We offer rigid uPVC profiles which are listed on our online shop in two colours: white and black. If other colours are required this can be done as custom manufacturing for larger production runs.

The type of uPVC used by some other industries

The type of uPVC used in industries such as windows and double glazing is slightly different to the material we use, whereby additional stabilisers are often added. These stabilisers may be needed due to the purpose of the product.

Another aspect that is different for windows and double glazing is the K value. This is a measure of the degree of polymerisation, or the molecular weight of the polymer chain. The K value varies across different applications. The K value for double glazing and window applications is higher than for profile extrusions, whereas the K factor for moulding applications is lower than for profile extrusions. 

What type of material is used to make flexible plastic extrusions?

When manufacturing flexible plastic profiles here at MKM Extrusions, we use a different type of raw material than when we make rigid profiles. To make the plastic flexible, plasticisers have been added to the PVC. So our flexible extrusions are made from PVC and not uPVC, the relevance of the ‘u’ meaning unplasticised. Our flexible PVC profiles are suitable for indoor use.

Our rigid uPVC is rigid like a ruler, although depending on the profile it may flex over a 3 metre length. Whereas our flexible PVC profiles are softer, you could put it around your waist like a belt.

Some other examples of products which can be made from flexible PVC by other manufacturers are wire casings, hose, gaskets, seals and straps.
