TPU Elastic Non-Woven GSM: Understanding Basis Weight Specifications
How GSM (grams per square meter) affects TPU elastic non-woven performance, cost, and applications
GSM — grams per square meter — is the first specification buyers ask about. TPU elastic non-woven GSM ranges from ultra-light 10 g/m² to heavy-duty 200+ g/m². The right GSM depends on your application.
Here's how to choose the appropriate basis weight for your needs.
GSM Ranges and Typical Applications
| GSM Range | Category | Typical Applications |
|---|---|---|
| 10-25 g/m² | Ultra-light | Disposable mask inner layers, hygiene product backsheets |
| 25-50 g/m² | Light | Surgical gowns (Zones 1-2), diaper backsheets, breathable apparel |
| 50-100 g/m² | Medium | Industrial filtration, automotive interiors, protective clothing |
| 100-150 g/m² | Heavy | Ear loop materials, industrial wipes, heavy-duty filtration |
| 150-200+ g/m² | Extra heavy | Structural components, heavy-duty industrial applications |
How GSM Affects Performance
Higher GSM generally means:
- Higher strength: More material = more tensile strength and tear resistance
- Higher cost: Raw material usage increases linearly with GSM
- Lower breathability: Thicker materials have higher resistance to air and vapor flow
- Higher stiffness: Thicker materials feel less soft and drapable
Optimization tip: Don't over-specify GSM. Many buyers request higher GSM than needed "just to be safe." This wastes money and can reduce performance (breathability). Match GSM to the actual mechanical requirements of your application.
GSM Tolerance and Quality Control
Manufacturing tolerance for GSM is typically ±10%. For critical applications, request ±5% tolerance. Consistent GSM is important for:
- Cost control: Variations affect material yield and final product cost
- Performance consistency: Barrier properties and breathability vary with thickness
- Converting efficiency: Laminating and slitting processes work best with consistent material
Custom GSM Options
We can manufacture TPU elastic non-woven at any GSM within our equipment range. Common requests include:
- Ultra-light 15 g/m²: For premium hygiene products where every gram matters
- Standard 30 g/m²: Most common for medical and hygiene applications
- Heavy 120 g/m²: For ear loops and industrial applications needing high strength
