فهم كثافة ورطوبة الصفائح البولي إيثيلين الفينولية: مرجع شير A/C Guide
في التصنيع ذات الأداء العالي، الاختيار الصحيح للمواد ليس مجرد إحتياج، بل متطلب تقني. سواء كنت تنتج أقدام حذاء، أو أرضيات بحرية، أو زخرفات cosplay معقدة، فإن أداء منتجك يعتمد على عوامل حاسمةين: Density و شدة الرطوبة (Shore Hardness).
خلاصة رئيسية للمشترين
At Damao, we provide a full spectrum of EVA foam sheets and rolls with densities ranging from 33 kg/m³ to 280 kg/m³ and hardness ratings from 15 to 80 Shore C (or 10 to 90 Shore A). Understanding how these two metrics interact is essential to optimizing both product performance and cost-efficiency.
1. EVA Foam Density: The Foundation of Support
Density refers to the mass of the foam per unit volume. In our production facility, we categorize EVA into three primary tiers to suit different structural needs:
Low-Density (33–80 kg/m³)
Ultra-lightweight and highly compressible. Best for maximum comfort in applications like helmet padding, yoga mats, and premium packaging inserts.
Medium-Density (80–150 kg/m³)
The versatile industry standard. Offers a perfect balance of flexibility and durability for shoe insoles, sports equipment, and heat-moldable props.
High-Density (150–280 kg/m³)
Rigid and heavy-duty. Ideal for structural components, orthotic supports, marine decking, and professional-grade cosplay armor that requires fine detailing.
2. Shore Hardness: Shore A vs. Shore C
Hardness measures the resistance to indentation. While often related to density, hardness can be adjusted through chemical additives in the EVA blend.
مقياس الشاطئ C
Used for softer, more compressible foams. This is the standard for the footwear and comfort industry.
- 15-35 Shore C: Therapeutic insoles
- 40-60 Shore C: Athletic midsoles
مقياس شور أ
Used for harder rubbers and semi-rigid plastics. Best for industrial and high-impact scenarios.
- 10-40 Shore A: شعور لطيف للمطاط
- 60-90 Shore A: سطحات صناعية صلبة
3. Performance Matrix by Application
ملكنا منتجات EVA ذات التفاصيل المخصصة are engineered to meet the specific demands of various industries:
| التطبيق | Typical Density | Typical Hardness | Why it matters? |
|---|---|---|---|
| Footwear (Insoles) | Low to Medium | 20–35 Shore C | Reduces foot fatigue & high comfort |
| Cosplay Armor | Medium to High | 40–70 Shore C | Heat-moldable & holds sharp edges |
| Marine Decking | عالي | 60–65 Shore C | UV resistance & structural integrity |
| Industrial Gaskets | عالي | 50–80 Shore A | Compression resistance & durability |
