PU Sole Safety Shoes: A Comprehensive FAQ Guide

Have you been thinking of starting a PU Sole Safety Shoe business but are confused with certain aspects of it?

In that case, this guide is specifically for you.

We have provided deep insight to all the frequently asked questions regarding PU Sole Safety Shoes and hope that you will find the solution to your query here.

Continue reading this guide and untangle the knots in your brain.

What is a PU Sole Safety Shoe?

Polyurethane, also known as PU, is a light and highly abrasion-resistant material that is perfect for an occupational safety shoe sole as it is really affordable and durable at the same time.

PU Sole Safety Shoes are usually preferred for hard labor and a strict working environment that requires quick movement and being on your feet for extended periods of time.

Since soles are a part of the safety shoe that is in direct contact with the ground, they are more prone to wear and tear and even potential hazards at the workplace; however, PU Sole Safety Shoes are specifically designed to overcome all these barriers and make your professional life a bit easier and less strenuous.

PU shoes are generally known as sports shoes and are great for trekking and running but have now become common in the safety shoe industry.

Is Rubber or PU Sole Better?

Rubber sole safety shoes are more suitable for an indoor setting, while PU Sole Safety Shoes are designed for an outdoor environment.

Rubber soles may show signs of wear and tear after being worn for long periods of time and are also not suggested to be worn daily.

On the other hand, PU soles are incredibly durable and can be worn for extended periods without causing discomfort or swelling to the feet.

For sole, you require a material that is hard enough not to let sharp objects pierce through your skin but soft enough to not provide cushioning and comfort while walking.

PU sole lives up to all these requirements, whereas rubber soles are permeable and can also absorb oil.

Why is a Polyurethane Sole Considered Good for Safety Shoes?

A polyurethane sole is known to provide unmatchable breathability, cushioning, and traction on all sorts of surfaces, which is why many people prefer them as an outsole for their safety shoes.

It is also highly flexible and provides room for a lot of movement, which means that they can adapt to any surface due to their flexibility and can provide maximum protection.

A PU Sole is also wear-resistant, which means that it does not show signs of withering away and is also not prone to tearing, which is a big plus point for safety shoes.https://www.youtube.com/embed/1RgAfBdgs8E?feature=oembed&wmode=opaque

Should I Choose PU Sole, PVC Sole, or TPR Sole for Safety Shoes?

The choice regarding which sole to incorporate in your order of safety shoes depends on the kind of work environment you possess.

Different soles serve different purposes, so they can only be judged based on their functions in their respective workplaces.

PVC soles, also known as polyvinyl chloride, are great for insulation and shock absorption and can be worn daily without the hazard of wear and tear; however, they are not the most comfortable soles and can not be used for quick movements, and would weigh you down while performing tasks.

Similar is the case with TPR soles, also known as thermoplastic rubber.

Even though they are still better than PVC soles as they possess excellent shock absorption and are even slip-resistant and water-resistant, and also maintain a firm grip, they are still more fit to be worn during adventures and not as safety shoes as they are not comfortable and can not be worn on a daily basis.

Hence, our experts would suggest you choose PU sole as they possess all the beneficial characteristics mentioned above and do not compromise on safety.

What are the Characteristics of PU Sole Safety Shoes?

PU Sole Safety Shoes are organically produced and hence, do not contribute to worsening the environmental conditions.

They also possess excellent shock absorption along with wear and tear resistance which makes them an in-demand product in the business industry.

PU Sole Safety Shoes also possess the characteristic of being oil-resistant as well as heat and cold resistance so that they can be used in any environment and all year round.

They are also abrasion-resistant and chemical-resistant.

Are PU Sole Safety Shoes Water-Resistant?

PU Sole Safety Shoes are water-resistant, making cleaning them much easier as the outsole usually attracts much dirt and gunk.

It also allows them to work in wet conditions without the threat of water seeping inside the shoe.

You can also easily travel to your workplace in rainy seasons without having to worry about ruining your expensive safety shoes.

Water makes the skin prone to blisters and irritation, so workers much prefer wearing water-resistant PU Sole Safety Shoes.

What is the Difference Between PU Sole Safety Shoes and TPU Sole Safety Shoes?

TPU soles, also known as thermoplastic urethane, have some similar features with PU soles, such as both are environmentally sound and friendly, possess excellent wear resistance, and are very strong materials.

However, PU soles have the upper hand on TPU soles as they possess better heat resistance, water resistance, and compression resistance as compared to TPU soles.

TPU soles are also not precisely comfortable as they are heavyweight and more rigid as compared to PU soles and also possess poor permeability, which means that, unlike PU soles that offer excellent resistance against objects piercing through the skin, TPU soles might expose the skin to potential hazards.

All in all, PU Sole Safety Shoes are the perfect package that offers complete protection along with comfort and fashion, whereas if you are buying TPU sole safety shoes, you would have to compromise on comfort and protection.https://www.youtube.com/embed/WIC9RN7FAmo?feature=oembed&wmode=opaque

Are PU Sole Safety Shoes Hydrolysis Resistant?

Hydrolysis is an age deterioration factor and is common for PU Sole Safety Shoes; however, many upgrades have been made to eradicate this factor, and now you can easily buy hydrolysis resistant PU Sole Safety Shoes.

Hydrolysis refers to the crumbling of a PU sole into tiny organic matter either due to exposure to heat, water, or prolonged use.

PU soles were subjected to chemical breakdown and instability when they were exposed to water, confined spaces, or extreme warmth; however, they have been upgraded to provide extreme stability in all environments and are not easily damaged anymore.

This slip resistance feature is a minimum requirement for all safety shoes according to the European standards EN ISO 20345 standard.

This standard requires safety shoes to have at least one type of slip resistance feature rated as SR, SRB or SRC.

  • SRA is slip resistance rating against ceramic floor wetted with diluted soapy liquid.
  • SRB is anti-slip rating tested on smooth steel wetted with glycerol.
  • SRC is a slip resistance rating for PU sole shoe that have both SRA and SRB properties.

What is Hydrolysis and How does it Relate to PU Sole Safety Shoes?

Hydrolysis is a chemical process in which water breaks down chemical bonds in the PU material resulting into PU crumbling overtime. This process is facilitated by water in vapor form and sped up by warmth or high humidity.

PU sole safety shoes can be made by either Polyester based PU or Polyether based sole.

Polyester based PU have low hydrolysis resistance and high oil resistance while vice versa for Polyether based PU sole.

Most safety footwear manufacturers use Polyester based PU sole in their PU sole safety shoes. These shoes normally last for about 1.5 years in tropical areas and 4 years in normal weather conditions.

EN ISO 20345-11 is the adopted European safety standards for protective footwear and was updated in 20111. This standard states that all safety footwear must have a front toe protection of about 200 joules.

The EN ISO 20345 has other safety standard classes coded as S1-S5 with each defining the safety feature it provides.

Buyers of the PU sole safety shoes can use the safety data sheet to guide them in selecting the right shoes.

What are Electrical Hazard Rated (EH) PU Sole Safety Shoes?

Electrical hazard rated (EH) PU sole safety shoes are made using non-conductive material to prevent electrocution. They do not allow electric current to pass through the body from the ground thus protecting the wearer.

EH PU sole safety shoes are also known as isolating safety shoes because they isolate you from the conductive ground.

Electrical hazard rated shoes are tested against the ASTM standards before they can be certified as EH rated shoes.

EH rated safety shoes differ from ESD shoes in terms of performance and protection offered. While EH rated shoes prevent electric current conductivity through the body, ESD prevent static charge build up.

EH rated shoes can lose their protective feature if the sole wears out and if used in wet areas. They should therefore be strictly used in dry workplaces and replaced immediately the sole wears out.

Which is better between Antistatic Safety and ESD Safety for PU Sole Safety Shoes?

Antistatic and ESD (Electrostatic Discharge) PU sole safety shoes provide protection against static shock, charge or spark. Static shock is caused when static electrical charges buildup in human body leading to flow of electric current between electrically charged objects.

Such incidences are common in industrial manufacturing industries, battery industries, aerospace, hospitals, telecommunication equipment manufacturers, etc.

Antistatic and ESD PU sole safety shoes are made from conductive material which conduct static electric charges into the ground.

Antistatic safety shoes provide contact electrical resistance of 0.1 to 1000 Mega Ohm (MΩ). It accomplishes this by conducting the static charges into the ground thus preventing build up and electric current flow through the body.

ESD safety shoes offer lower electric resistance of 0.1 to 100 (MΩ). They safely conduct the flow of static charges into the ground.

Unlike antistatic safety shoes that just conducts charges into the ground, ESD safety shoes does it safely and in controlled way.

It also offers protection against a wide range of harmful static electric charges that may lead to shock or explosion. Workers can use ESD or antistatic safety shoes when working in industries where static electric charges are common.

They can wear ESD PU sole safety shoes for better protection.

Steel or Composite Toe for PU Sole Safety Shoes, which is better?
