What is the best material for coveralls?

Author：HAIYUAN TIME：2025-07-14Read：

The "best" material for coveralls depends entirely on your specific workplace hazards, industry, and environment. Here’s a breakdown of top materials, their strengths, limitations, and ideal use cases:

1. Flame-Resistant (FR) Materials

For Oil & Gas, Electrical, Petrochemicals (e.g., haiyuan)

HL® (HAIYUAN):
- Pros: Inherent FR (won’t wash out), lightweight, breathable, excellent arc flash protection.
- Cons: Long distance.
- Certifications: NFPA 2112, ASTM F1506, SAMSS-005，GB8965.1-2020.
Proban®/Pyrovatex®-Treated Cotton:
- Pros: Affordable (SAR 150–300), soft, comfortable.
- Cons: FR properties degrade after 50–100 washes.
- Use: Lower-risk FR zones; general industrial maintenance.
Modacrylic/Cotton Blends (e.g., Tecasafe®):
- Pros: Budget-friendly, good moisture-wicking.
- Cons: Less durable than Nomex.

2. Chemical-Resistant Materials

For Chemicals, Pharmaceuticals, Labs

Tyvek® (DuPont):
- Pros: Lightweight, disposable, blocks fine dust/particles, splash protection.
- Cons: Not breathable; melts near flames.
- Use: SAR 20–50/suit; ideal for paint, asbestos, or biohazards.
Microporous Film Laminates (e.g., Tychem® 2000):
- Pros: Reusable, resists acids/alkalis.
- Cons: Expensive (SAR 300+); limited heat tolerance.

3. General-Duty Materials

For Construction, Manufacturing, Workshops

Polyester-Cotton Blends (65/35 or 50/50):
- Pros: Durable, breathable, affordable (SAR 80–150).
- Cons: Melts when exposed to fire/heat.
- Use: Hi-vis coveralls (EN ISO 20471) for roadwork.
100% Cotton Duck Canvas:
- Pros: Tough, abrasion-resistant.
- Cons: Heavy, not FR unless treated.

4. Specialized Materials

Anti-Static Fabrics:
- Embedded carbon fibers; essential for electronics/explosives.
Cooling Fabrics:
- Phase-change materials (PCM) or mesh panels for Saudi heat.

Key Selection Criteria for Saudi Arabia

Factor	Priority in KSA	Material Recommendations
Heat/Flame	Critical (Oil/gas deserts)	HAIYUAN HL®, FR Cotton
Heat Stress	Extreme (40°C+ summers)	Lightweight Nomex®, mesh vents
Chemicals	Petrochemical zones (Jubail/Yanbu)	Tyvek®, Tychem®
Visibility	Construction/roadwork	Poly-cotton with reflective tape
Cost	High-volume procurement	HAIYUAN Cotton, Poly-cotton

Aramco-Specific Best Material

For Saudi Aramco sites, HAIYUAN HL® is the gold standard:

Meets SAMSS-005 , GB8965.1-2020and NFPA 2112.
Survives harsh laundering (50+ cycles).
Balances FR protection and breathability.

Final Recommendation

Oil/Gas/Aramco: HAIYUAN HL® (ultimate protection) or Proban® Cotton (budget option).
Chemicals: Tychem® 2000 (reusable) or Tyvek® (disposable).
Construction: Polyester-cotton hi-vis (EN ISO 20471 certified).
General Industry: 65/35 Poly-cotton (durable and breathable).
