What Does EN388 4131 Mean?

The CE EN388:2016+A1:2018 mechanical risk rating on the YZ-N304 is 4131. Here is what each digit means in practice:

Digit	Performance	Level	Real-world meaning
4	Abrasion resistance	Level 4 (highest)	8,000+ cycles before breakthrough — handles rough concrete, pallet edges and repeated handling
1	Coup cut resistance	Level 1	No cut protection — designed for grip and breathability, not sharp edges
1	Tear resistance	Level 1	Handles normal pulling and tugging; avoid heavy loads with sharp corners
1	Puncture resistance	Level 1	Suitable for general warehouse and construction tasks without heavy puncture hazards

Best practice: YZ-N304 excels at abrasion and grip — but for sharp metal, glass or rebar, switch to YZ-N301 (HPPE, EN388 4543) or YZ-C401 (HPPE+fiberglass, EN388 4543).

Nitrile Micro-Foam: How It Works

Unlike smooth nitrile palm coating, the YZ-N304 uses a nitrile micro-foam coating — a light, porous nitrile layer with thousands of tiny air cells baked into the surface. This gives three key advantages:

Feature	Nitrile Micro-Foam	Smooth Nitrile	Crinkle Latex
Breathability	High — air cells allow heat dissipation	Low	Low
Grip (dry surface)	Excellent (micro-suction cup effect)	Good	Very good
Grip (light oil/wet)	Good	Moderate	Good
Weight / dexterity	Light (0.40-0.50 mm coat)	Moderate	Heavy
Cold sensitivity	Minimal (air cells insulate)	Moderate	Stiffens in cold

The micro-foam finish is especially suited to dry and lightly-oily surfaces where workers need all-day comfort without heavy glove weight — common in construction finishing, warehouse picking and assembly line tasks.

Industry Applications

Industry	Tasks	Why YZ-N304
Construction	Finishing work, drywall, scaffolding, material handling	Abrasion 4 handles rough surfaces; breathable for all-day wear
Warehouse & logistics	Pallet handling, order picking, loading/unloading	Strong grip on cardboard, plastic wrap and dry goods
Assembly lines	Light assembly, parts installation, quality inspection	Thin micro-foam retains dexterity for precise handling
Maintenance	Facility maintenance, tool handling, cleaning	Comfortable for extended wear
Agriculture	Greenhouse work, harvesting, equipment handling	Breathable for warm environments, grip on wet plants

Not recommended for: heavy oil immersion (use YZ-N303 Full Nitrile), sharp metal/glass handling (use YZ-N301 HPPE), or chemical exposure beyond pH 5-9.5 range.

Nitrile Foam vs Sandy Nitrile vs Smooth Nitrile

Coating	Breathability	Grip (Dry)	Grip (Wet/Oil)	Dexterity	Best For
Nitrile micro-foam (YZ-N304)	High	Excellent	Good	Excellent	Construction, warehouse, assembly
Sandy nitrile (YZ-N302)	Moderate	Excellent	Excellent	Very good	Automotive, precision
Smooth nitrile	Low	Good	Moderate	Good	General purpose
Crinkle latex	Low	Very good	Very good	Moderate	Heavy construction
