1. Ewyn EVA (Asetad Vinyl Ethylene)
Nodweddion:
- Fine and uniform cell structure (smooth surface)
- High elasticity and toughness
- Good water resistance and durability
- Can be die-cut, heat-formed, laminated, or printed easily
- Density range: 30–300 kg/m³
- Ar gael yn various colors and hardness levels
Typical Uses:
- Sports mats, yoga blocks, swimming belts
- Packaging inserts (high-end electronics, offer)
- Shoe soles, kneeling pads, tegannau
Pros: Smooth finish, gwydn, addasadwy, diwenwyn
Cons: Slightly more expensive than EPE
2. Ewyn EPE (Polyethylen Ehangu)

- Soft and flexible, excellent amsugno sioc
- Water and chemical resistant
- Density range: 15–50 kg/m³
Typical Uses:
- Pecynnu (electroneg, gwydr, dodrefn)
- Edge protectors, foam tubes, inswleiddio
Pros: Low cost, good cushioning, ailddefnyddiadwy
Cons: Rougher surface, less firm than EVA, not suitable for precision cutting
3. Ewyn Sbwng (Polyurethane or PU Foam)
Nodweddion:
- Open-cell structure (soft and breathable)
- Very compressible and comfortable
- Absorbs water easily
- Density range: 10–60 kg/m³
Typical Uses:
- Seat cushions, amsugno sain, cosmetic sponges
- Cleaning products, gaskets, padin
Pros: Very soft, cyfforddus, low cost
Cons: Absorbs water, poor durability outdoors, not suitable for heavy loads
