What Is Bottle Brush Baby

The material of the bottle brush

The handle of the bottle brush is generally polypropylene, which is a safe material that does not contain phenol. The brush body is generally nylon or sponge or a combination of the two. The brush shaft is mostly stainless steel and polypropylene. Why is it designed like this?

1. Brush head part

sponge. Good water absorption, good air permeability and strong shrinkage. The sponge on the bottle brush is flexible enough to closely fit the inner wall of the bottle, remove dirt from all corners of the bottle, and has good abrasion resistance, which will not cause scratches on the inner wall of the bottle.

nylon. Nylon is the first synthetic fiber to appear in the world, with good abrasion resistance and excellent elasticity. The brush head is made of nylon and made into a ball shape, which can extend the bristles to all corners of the baby bottle and the spiral of the baby bottle. The bristles have strong hardness, can effectively brush stubborn stains, and have better decontamination ability.

2. Brush shaft part

stainless steel. The stainless steel brush shaft is used with nylon bristles, and stainless steel is used for fixed bristles. Why use stainless steel? First, because of the high hardness of stainless steel, stainless steel with a certain diameter is not easy to bend and damaged by people, and it will not loosen after fixing the bristles, and it is not easy to shed. Second, because of the small size of stainless steel, it can be extended into the bottle at will, especially the straw brush, the wire thickness The brush can reach inside the straw to clean the stains, which really helped Momma a lot.

Polypropylene. Polypropylene is often used as the brush shaft of sponge brush heads for three reasons: one is that the sponge fixture should not be too small, otherwise it will not be strong. Polypropylene is about the thickness of the little finger, which is convenient to connect with the sponge; the second is that it has good hardness and toughness and can guarantee use The process is stable and non-slip; third, the material is safe and non-toxic, which can prevent internal pollution.
