The Benefits of Using Polyurethane Aviation Wheel Chocks.

Wheel chocks are a very important component in Aviation safety. When purchasing aviation wheel chocks, two of the material choices available are wood and polyurethane. While wood wheel chocks were the first aviation chocks designed and they are still in use in many locations, upgrading to polyurethane wheel chocks is a smart choice for a number of reasons.

One of the most important reasons for using polyurethane wheel chocks is safety.

Choosing a polyurethane product that is more structurally sound is far more important than saving a little money upfront on lower priced wood models, because it will eventually cost more in the long run. AtCheckers Industrial Safety Products, we see safety as an investment and not a cost, which is why we have become one of the largest manufacturers of quality wheel chocks in the world.

The major advantages to choosing polyurethane aviation wheel chocks over those made from wood include:

Polyurethane wheel chocks outperform and hold up better than wood wheel chocks.
While their initial cost is higher than wood, polyurethane wheel chocks are a much better value in the long term.
Polyurethane aviation wheel chocks are tested and approved for military use.
Unlike wood, polyurethane wheel chocks are resistant to fuels, oils, and lubricants.
Polyurethane wheel chocks require no maintenance or painting (wood chocks require regular painting).
Wood wheel chocks can crack, splinter, and rot, which can result in foreign object damage to aircraft and injury to personnel.
Wood wheel chocks exposed to wet conditions soak up water, which makes them heavy and hard to handle.
The structural integrity of wood wheel chocks can be compromised as a result of warping, rotting, or cracking. None of these are an issue with polyurethane wheel chocks.

Through this process your components could attain greater performance in:

What is Polyurethane?
Polyurethanes are a general term that is used for a wide range of polymers but they are specifically high molecular weight polymers which are based on Isocyanate chemistry. All Urethanes are produced with a reaction between 3 components:

• A Polyol (PPG, PTMEG and Polyester)
• An Isocyanate (TDI, MDI, NDI)
• A cross-linker / Chain extender (Diamine, Diol and Triols)

In General the Polyol and Isocyanate parts are preblended liquids called Pre-polymers. This is then hand or machine blended with the cross linker, poured into a mould and cured to produce the end component.

There are many different families of polyurethanes, for example; Castable Elastomers, Rigid and Flexible foam, Adhesives, Sealants & Coatings.

Handles Urethane Products specialise in manufacturing castable Polyurethane products, which are true engineering materials. Castable Polyurethanes are true elastomers, the definition of which is a material that can be extended to at least twice its length and then return to its original form.

Why Polyurethanes? 
The major characteristic of these Polyurethanes are their extraordinary physical properties and the variety of strengths that are available between the different families of urethanes. There are two main reasons for using polyurethanes; their physical performance and their cost effectiveness. Below is a chart detailing the advantages of using Urethanes over other materials.

Polyurethanes advantages over other materials

ChengDu Handles Trade Co., Ltd have supplied industry standard and custom polyurethane components to the automotive industry for over 10 years using Engineering grade cast-able polyurethane materials. In collaboration with our customers, we also develop new and better solutions through part design and our extensive knowledge of polyurethane chemistry, which means we can tailor suit polyurethane mouldings to your specific requirements.
