Foam Massage Roller

What is the EVA material of the foam massage roller made of?

EVA is an ethylene-vinyl acetate copolymer (also called ethylene-vinyl acetate copolymer). It is made by copolymerizing ethylene (E) and acetic acid (VA). The English name is Ethylene Vinyl Acetate, or EVA for short.

EVA foam sheets are widely used in every corner of life, and people’s lives are inseparable from EVA products. General application scope: EVA color sheet, EVA midsole, EVA.PE high foam, EVA? MODEL sheet, EVA flame retardant foam, EVA toys and gifts, EVA sporting goods, EVA various gaskets.

Features:

Water resistance: closed cell structure, non-absorbent, moisture-proof, good water resistance.

Corrosion resistance: Resistant to seawater, grease, acid, alkali, and other chemical corrosion, antibacterial, odorless, and non-toxic.

Processability: No joints, and easy to process such as hot pressing, cutting, gluing, and lamination.

Anti-vibration: high resilience and tensile strength, strong toughness, and good shock-proof/buffering properties.

Thermal Insulation: Excellent in heat insulation, cold protection and low-temperature performance, and can withstand severe cold and exposure to the sun.

Sound insulation: closed cells, good sound insulation effect.

Is it better to have a solid yoga post or a hollow one?

Yoga columns are also called foam rollers, yoga rollers, etc. As the name suggests, they are used for rolling, and their main function is to relax and relieve tight muscle groups. The density of a solid yoga column is inherently higher than that of a hollow yoga column, and rolling requires more force. When rolling with force, the deformation of the column is smaller, and the rebound force to the body is naturally greater.

Since the hollow yoga column is hollow in the middle, it is lighter in weight and will not be difficult to roll. In addition, high-toughness materials are generally used to support the middle part. When pressed, the deformation range will be larger, and the rebound force to the body will be smaller. It is easier for beginners to get started. In addition, most of the yoga columns currently on the market are hollow. When choosing, it is best to choose from the density, material, size and durability.
