Understanding Dipped Gloves: Polyurethane vs. Latex vs. Nitrile

Published by Pyramex

While leather gloves have been around for thousands of years, dipped gloves are relatively new. OSHA considers the last 50 years, the “golden era of hand protection.” One of the most significant innovations during this time was the creation of dipped gloves which was a game-changer for the personal protective equipment (PPE) industry.

Today, the PPE industry has moved even further beyond the original dipped latex glove and is able to offer a dipped coated glove in a variety of materials that are great for different industries and applications depending on the worker and job need.

Anatomy of Dipped Gloves

Like leather gloves, there are varying ways dipped gloves can be made and different elements that affect their makeup.

Liners are the first central component to a dipped glove. There are three main types of liners. Nylon, which is highly resistant to abrasions, highly absorbent, and has increased touch sensitivity and dexterity. Polyester, which is resistant to shrinking and stretching, plus is quick drying. Higher performance polyethylene (HPPE), which provides maximum strength cut resistance with minimum weight. There can even be a blend of these liners.

The gauge of the liner can impact rating and work application. Gauge is the number of stitches per inch. The higher the liner gauge the better the fit, dexterity, and tactile feel. 7g to 18g is the typical range gauge for dipped gloves.

Dipped Glove Coatings

Polyurethane

Polyurethane gloves are the value work glove. They have low particulate shed and offer good touch sensitivity, breathability, and dexterity. These gloves grip well without being sticky and have good tensile strength and abrasion resistance.

They are popular for jobs that require small parts handling, such as electronics, aeronautics, glass/sheet metal handling, or in clean rooms. Polyurethane gloves are not recommended for use above 175° F (79° C).

Latex

Latex gloves offer increased elasticity/flexibility in extreme temperatures (0° F/ -18° C to 300° F/ 149° C) and are cut, abrasion, and tear-resistant. They are well suited for jobs in both wet and dry environments. These gloves are often thought of as “rubber gloves” due to their resistance to water and alcohol.

Latex gloves are popular in construction, glass manufacturing, warehousing, and general materials handling. They should not be used around hydrocarbon, organic solvents, flames, or by people with a latex allergy.

Nitrile

Nitrile gloves are a great latex alternative that absorbs oil and has an outstanding grip. Nitrile micro-foam gloves are three times more puncture resistant than rubber, though not as durable. They are also breathable and water repellant.

Sandy nitrile gloves have a strong grip in wet, dry, and oily conditions. Oil will not penetrate the glove as with micro-foam. However, sandy nitrile gloves are not as breathable due to their manufacturing process.

Both types of nitrile gloves are good to use in oily areas, construction, sanitation, glass/sheet metal handling, agriculture, and automotive/aircraft maintenance. They should not be used around adhesives.

Grip

Grip is another main component of a glove. The different coatings offer varying types of grips that can affect what environments they work best in. There are five main grips:

  • Smooth – great dry grip, does not absorb liquids.
  • Micro-foam – excellent dry grip, enhanced touch sensitivity, channels liquids away.
  • Crinkle – outstanding grip in wet and dry conditions, channels liquids away.
  • Sandy – enhanced grip in wet/harsh conditions.
  • Pattern – durable, reinforces grip performance.

Dipped Glove Safety Standards

The American National Safety Institute (ANSI) creates safety standards by which gloves are tested in the US. This organization is influenced by industry experts, consumer groups, and government bodies in order to help classify safety equipment. For dipped gloves, many factors are included in the standard to best test glove safety. These factors include cut resistance, puncture resistance, abrasion resistance, and back of hand impact protection. Each of these factors is measured on its own scale and the level of protection is denoted on the glove and its packaging.

No matter what industry PPE is needed for, Pyramex gloves are sure to increase worker safety and help workers perform at their peak.
