Winter Work Gloves OEM in China: How Coating Technology Affects Cold-Weather Grip

For potential customers of Winter Work Gloves OEM in China, the performance of the coatings used is as important as the level of thermal insulation. Coatings on gloves can become stiff and inflexible in very cold conditions. The coatings can also become rigid and stiff in the presence of moisture or oil. Insulating materials can restrict the movement of the fingers and reduce the grip of the gloves.

When reviewing winter hand protection, our specialists consider a balance of the coating, the materials used in the lining of the gloves, the condition of the surface the gloves come in contact with and the type of work the gloves will be used for.

Why Does Coating Performance Change with Temperature?

Friction of a coating conforms to an object and determines the grip of the coated surface. Cold temperatures reduce both conformability and surface friction.

Some of the phenomenon that impact this are:

•   Stiffening of the polymer: At lower temperatures, a coating can become stiffer and less flexible and be unable to make full contact with an irregular surface.

•   Interfacial Lubrication: At the interface of a coating and an object, a thin film of oil or water can reduce surface friction. Surface texture of the object and the coating can not displace the film.

•   Cold Fingers: Bulky gloves and very cold temperatures can reduce the grip of the fingers. More effort may be required to hold a tool.

During a cold temperature condition, the surface geometry of the coating can impact the performance more than the thickness of the coating.

Coating flexibility can also impact the bending movement of the glove.

Latex vs. Nitrile vs. PU vs. PVC: Coating Performance Compared

Latex and Nitrile gloves can be rigid, but polyurethane (PU) coating materials, or Phthalate (PVC) coating materials can provide greater flexibility.

While evaluating Winter Work Gloves OEM in China, it is important for customers to analyze the coating chemistry for flexibility and oil and flexibility and determine how it will impact the performance and usage of the gloves.

Performance Characteristics	Best-Fit Applications	Limitations
Latex	Wet construction, forestry	Limited oil resistance; latex allergies
Nitrile	Oily metal, machinery	Low-temperature flexibility varies
PU	Warehousing	Standard thin coatings may lack grip
PVC/Nitrile	Outdoor wet maintenance	Cold flexibility varies

In the case of patterned textures, LATEX performs better for capturing wet surfaces. For the wet timber industry, Nitrile offers better resistance to oils and fats.

Importance of Surface Texture in Grip

Different materials have different surface textures:

•   Sandpaper Coating: A coating resembling sandpaper improves traction on oily surfaces.

•   Foam Coating: A foam coating aids surface condensation and liquid water drainage.

•   Crinkled Coating: Irregular coatings, like crinkled coatings, may help surface drainage.

•   Smooth Coating: Smooth surfaces allow even contact with the whole area.

Some special coatings, for example, maybe able to help surface grip for ice, but generally speaking, a coating won't help a surface grip for ice.

What Does Coating Coverage and Thermal Liners Mean for a Winter Glove?

A winter glove provides protection against cold and wet conditions. The protection against these conditions is determined by the liners and coatings.

Coating/Lining	Function	Limitations
Palm-Coated	Lining flexibility; Grip in coated area	No coating on back of hand, less protection
Double-Dipped	Additional coating layer	Possible increased stiffness
Fully-Coated	Extended coating coverage	Restricted glove breathability
Dual-Thermal Liner	Insulation and structural support	Increased liner bulk

One of the design trade-offs is to increase insulation against the cold; however, there is a limit to how well a structure can provide grip. Bulk can obstruct the user from performing the glove's intended function.

For example, a 7 gauge terry acrylic inner liner provides better insulation against the cold compared to a 13 gauge outer liner; however, a 13 gauge outer liner can provide a structure that better facilitates dexterity.

Choosing Coating Technology for Different Cold-Weather Applications

The most suitable construction depends on whether the main hazard is moisture, oil, abrasion, sharp edges, or repeated contact with cold materials.

Application	Primary Risk	Coating Selection
Cold storage	Repetitive handling, reduced dexterity	Flexible PU or nitrile
Winter construction	Wet timber, rough surfaces	Textured latex or sandy nitrile
Oilfield maintenance	Oily tools, cold metal	Sandy nitrile
Forestry	Wet wood, abrasion	Crinkle latex or nitrile
Outdoor utilities	Rain, snow, prolonged wet exposure	Fully coated PU or PVC/nitrile

Heavier coatings may not be necessary for some uses if dexterity and cold protection sufficient for contact are provided. Oilfield and steel handling may also require cut resistance.

These assertions require on-site proof.

How Can Cold Weather Grip and Protection be verified?

When sourcing Winter Work Gloves from China, it is important to be aware that certified protection features may be different from application specific features, e.g. Winter Work Glove applicability.

Understanding EN Standards

The focus of each standard is as follows:

•   EN 511: Protection from cold, wet work

•   EN 388: Cut, tear, puncture and abrasion protection

•   EN ISO 21420: General requirements, sizing and ergonomics of gloves

•   EN 511 and EN 388 do not stipulate testing for low temperature flex or grip.

Grip and Durability Evaluation

We suggest the following tests for evaluation of glove samples:

•   Flexibility: Test sample to determine if the coating or lining of the glove has cracked or lost flexibility.

•   Grip: Sample should be tested to determine if it has friction on dry, wet and oily surfaces.

•   Waterproof/Water Repellant: Barrier Test Sample should be tested to determine if the coating and/or lining is continuous. Test sample to determine if the lining of the glove has absorbed moisture.

Production samples should be tested to ensure they conform to the approved samples.

Test requirements should be defined by the buyer to include accepted test temperature, the surface to be used in the test (the substrate), and the force to be applied.

NMSafety Model	Coating and Construction	Product Focus
NBR1350DS-ECO	13G recycled PET and 7G terry acrylic liner	Insulated grip with recycled materials
NM1355DF-ECO	RPET/acrylic liner	Half-coated foam latex; elastic handling and insulation
DY1850DSW-H4	ANSI A4 / ISO Cut Level D; Sandy nitrile; Dual Liner	Wet handling with cut protection
PU7530S-W	Sandy PU palm coating; Nylon/acrylic liner	Extended liquid protection, and cold flex
PVC4530W	Thinsulate lining; PVC/Nitrile Blend	Industrial handling

Winter glove selection is illustrated by these examples, where the whole construction warrants consideration as opposed to coatings alone.

OEM Customization, Pricing, and Purchasing Requirements

In order to receive quotations, the following information should be provided to suppliers:

•   Pairs handled, thermal exposure, and materials handled.

•   Coating requirements, texture, coverage and thermal linings.

•   Required EN/ANSI classifications and supporting test reports.

•   Sample acceptance, Branding, and Packaging.

•   Batch size and quantity, delivery schedule.

Molding cycles affect the OEM's price. Complex or atypical designs should be justified by workplace risks.

Selecting winter work gloves from Chinese OEMs is usually based on thickness or cost, and not the actual working conditions. We at NMSafety offer PVC/Nitrile, PU, Latex and Nitrile coated Work Gloves. Additionally, we offer OEM customization. Visit our Winter Work Gloves page to learn more.
