2. Rubber rain boots

Advantages: It is die-cast; but its insulation and anti-corrosion properties are relatively good; it is anti-slip and breathable; most importantly, it has high comfort.

Disadvantages: production efficiency is relatively low; the appearance of the finished product is relatively rough; it is difficult to control the fineness of the process; and the material price is relatively expensive.

Extended information:

The reinforcing properties of rubber mainly affect tensile strength and tear strength. The general rule is: when the particle size is the same, high-structure carbon black has a greater reinforcing effect on amorphous rubber and generally has higher tensile strength. and tear strength. The structure of rubber is also the most important factor affecting the conductive performance. The dendritic structure is easy to form intertwined conductive paths in the rubber, which will improve the conductive performance.

PVC is a polar amorphous polymer with strong interactions between molecules. It is a hard and brittle material with low impact strength. After adding the impact modifier, the elastomer particles of the impact modifier can reduce the total craze-induced stress, and use the deformation and shear bands of the particles themselves to prevent the craze from expanding and growing, and absorb the impact energy transferred into the material. , thereby achieving the purpose of impact resistance. The particles of the modifier are very small, which facilitates increasing the amount of the modifier per unit weight or unit volume, increasing its effective volume fraction, thereby enhancing the ability to disperse stress. At present, organic impact modifiers are widely used.
