What is the difference between EVA foam, Цахээний хөндий, and sponge foam

1. EVA хөөс (Этилен винил ацетат)

Онцлогууд:

• Fine and uniform cell structure (гөлгөр гадаргуу)
• High elasticity and toughness
• Good water resistance and durability
• Can be die-cut, heat-formed, laminated, эсвэл хэвлэсэн easily
• Density range: 30–300 kg/m³
• Хэрэгтэй байна various colors and hardness levels

Typical Uses:

• Sports mats, yoga blocks, swimming belts
• Packaging inserts (high-end electronics, хэрэгсэл)
• Shoe soles, kneeling pads, тоглоом

Pros: Smooth finish, бат бөх, тохируулах боломжтой, хоргүй
Cons: Slightly more expensive than EPE

2. EPE хөөс (Өргөтгөсөн полиэтилен)

Онцлогууд:

• Lightweight with larger air bubbles / open cells
• Soft and flexible, excellent цочрол шингээх
• Water and chemical resistant
• Density range: 15–50 kg/m³

Typical Uses:

• Сав баглаа боодол (Электроник, шилэн, тавилга)
• Edge protectors, foam tubes, тусгаарлагч

Pros: Low cost, good cushioning, reusable
Cons: Rougher surface, less firm than EVA, not suitable for precision cutting

3. Хөвөн хөөс (Polyurethane or PU Foam)

Онцлогууд:

• Нээлттэй эсийн бүтэц (soft and breathable)
• Very compressible and comfortable
• Absorbs water easily
• Density range: 10–60 kg/m³

Typical Uses:

• Seat cushions, дууны шинжих, cosmetic sponges
• Cleaning products, gaskets, дэвсгэр

Pros: Very soft, тохилог, low cost
Cons: Absorbs water, poor durability outdoors, not suitable for heavy loads
