At present, the home sandals on the market are mainly plastic materials, which are divided into PVC (polyvinyl chloride) and EVA (ethylene-vinyl acetate copolymer).
Characteristics of EVA
The chemical name of EVA is ethylene-vinyl acetate copolymer, which is a polymer that is flammable and produces carbon monoxide and carbon dioxide after combustion. It has good aging resistance, water resistance, ozone resistance and chemical stability.
The characteristics of EVA are as follows:
Shock resistance: there is resilience and high tension, toughness is very good, so it is a very good shock and buffer material.
Water resistance and sound insulation: it is a closed bubble structure, will not absorb water, moisture-proof effect, sound insulation effect is also very good.
Insulation: the bubble structure makes EVA also have good thermal insulation and insulation performance.
Easy processing: EVA has no fixed joint, hot pressing, cutting, fitting processing is relatively easy.
Corrosion resistance: EVA itself antibacterial, non-toxic and tasteless, no pollution, has a good acid and alkali corrosion resistance.
Application: EVA material can be made of shoes, film, wire and cable, toys, hot melt adhesive, EVA emulsion and other products.
Characteristics of PVC
The chemical name of PVC is polyvinyl chloride, which is a white powder with an amorphous structure
When using PVC materials, it is necessary to add some stabilizers to them. Application: PVC is widely used in building materials, industrial products, daily necessities, floor tiles, artificial leather, floor leather, wire and cable, packaging film, plastic bottles, foam materials, fibers and other aspects have applications.
Good air tightness and impermeability, its strength is also relatively high.
Light weight: PVC products such as pipes, relatively light quality, easy to load and unload.
Good insulation performance, PVC is often used in the production of wire and cable plastic sleeves.
Does not affect the water quality: tested and verified, PVC made of pipes and fittings, will not affect the water quality, is the best pipe for tap water piping.
Good coloring, not only can show the natural color, but also can make a beautiful fantasy color, rich product appearance.
Which is better, EVA or PVC?
PVC is one of the five commonly used plastics and has a wide range of applications. And EVA is an environmentally friendly material, tensile toughness is stronger than PVC, the film made of feel and PVC is very similar, there is a slight sticky feeling. EVA soles are more comfortable to wear than PVC soles, but generally EVA is more expensive than PVC. In general, EVA and PVC have their own characteristics, can not simply say who is better than who, in daily life, if you use two materials, according to their own needs to choose.
