1. Labor protection shoes Polyurethane bottom (PU):
Polyurethane is short for Polyurethane, the English name is polyurethane, it is a polymer material, made of A / B / C polyester foam, oil and water two. Is a new organic polymer material, known as "the fifth largest plastic", used to make high-grade leather shoes, sports shoes, sneakers and so on.
Advantages: low density, soft texture, good elasticity, comfortable and light to wear; good oxidation resistance, excellent wear resistance, flexural resistance, high hardness; excellent shock absorption, anti-skid performance; Good chemical resistance; Perishable conducive to environmental protection, not easy to wrinkle.
Disadvantages: strong water absorption, easy yellowing, easy to break, poor elongation, water resistance, perishable bottom, poor air permeability.
2. Labor protection shoes leather soles:
Leather sole is a kind of labor protection shoes that can breathe automatically and bring the feet to breathe. The breathability is good and not bored. It can automatically release the absorbed sweat to keep the feet dry. Leather soles mainly leather, higher prices. Its advantages are easy to shape, the same type, fit, good elasticity, can reduce the impact and not easy to fatigue, ventilation, moisture absorption, etc., while easy processing, easy to display beauty. Hard texture is not easy to pierce, but after being soaked in water, oil is easy to warp deformation or decay. Its main features:
① better thermal insulation to ensure that the foot in the shoe the right temperature
② light weight, weight per square centimeter 0.95 ~ 1.05 grams, just the same density and water. Can be waterproof and release moisture when the shoes are no longer wet, to ensure that the shoes in a comfortable state.
③ unique three-dimensional fiber structure, labor-protection soles do not break when bent 180 degrees. Can quickly adapt to the foot shape, can effectively support the ground impact, than other materials of the same thickness soles more effective protection of the feet.
3. Labor protection shoes EVA bottom:
Ethylene Vinyl Acetate - Polymer materials. Commonly used in jogging, walking, casual shoes, foot training shoes in the end. Light weight, easy to process, no wear, no oil.
Advantages: lightweight, flexible, good flexibility, easy to wrinkle, has excellent coloring, suitable for all kinds of climate.
Disadvantages: easy to absorb water, easy to corrosion adverse environmental protection, easy to dirty.
4. Labor protection shoes MD at the end:
MODEL or PHYLON dragon collectively, is an EVA secondary high-pressure molded products. MD soles inside must contain EVA, MD also called PHYLON end. Such as MD = EVA + RB or EVA + RB + TPR Some shoes are RB + PU and so on.
Advantages: lightweight, flexible, thin appearance, good softness; easy to clean; hardness, density, tension, tear, good elongation.
Disadvantages: not easy to corrosion adverse environmental protection, easy to wrinkle at high temperatures, easy to shrink; durability is poor, the use of a long time its damping force will be reduced, poor ventilation.
5. Labor protection shoes rubber sole (RB):
RB is an acronym for English rubber (rubber); hot compression molding, sub-natural rubber and recycled rubber. Weigh, not greasy, molded at the end of the surface must be coarse grinding, easy to shorten the heating, the color is inconsistent.
Advantages: good wear resistance, non-slip, flexible, not easy to break, good softness, good extension, shrinkage and stability, good hardness, good bending, waterproof.
Disadvantages: heavier, easy to spit cream (quality problems), not easy to corrosion (environmental problems); not hard, easily pierced; breathable, hygroscopicity is not good, afraid of oil soaked, should not be in the car gas station and other contact with the oil Place to wear.
※ rubber foam
The weight of the rubber than the light at the end, a rubbery smell, with your fingers on time, the surface rebound significantly than the average soles, poor wear resistance.
※ High pressure polyethylene rubber bottom
High-pressure polyethylene and rubber flavor of the main ingredients soles, rubber and plastic and use.
Raw rubber end: quality, more expensive, not resistant to oil, heat-resistant. Easy to change color.
