Protect toe shoes

Due to the protection of toe shoes sole production, there are different materials, leather soles, rubber soles and polyurethane soles, different advantages and disadvantages of different shoes. Xiaobian today and we introduce the main, what are the advantages and disadvantages of rubber soles:

Rubber sole, through the hot compression molding, divided into natural rubber and recycled rubber. Weigh on the oil, the mold at the end of the bonding surface must be coarse, easy to shorten the heating, the color is inconsistent.

Protect the toe shoes manufacturers said its advantages are: good wear resistance, non-slip, flexible, easy to break, good flexibility, good ductility, shrinkage and stability, good hardness, good bending, waterproof. Disadvantages are: heavier, easy to spit cream (quality problems), not easy to corrosion (environmental problems); not hard, easy to tie through; breathable, hygroscopicity is not good, afraid of oil soaked, not in the car gas station and other contact oil Place to wear.

Rubber foam: the weight of light rubber than the bottom, a rubber flavor, with your fingers on time, the surface rebound significantly more than the average soles, wear resistance is poor.

High-pressure polyethylene rubber sole: high-pressure polyethylene and rubber flavor of the main ingredients soles, rubber and plastic and use.

Raw rubber end: quality, more expensive, not oil, heat, easy to change color.

The mid-1950s began industrial production in the United States. To protect the toe shoes industrial production methods can be divided into two categories: one is the polybutadiene or styrene-butadiene rubber and SAN resin on the roller mechanical blending, or the two latex blend, and then copolymerization; the other One is the addition of styrene and acrylonitrile monomer to polybutadiene or styrene-butadiene latex with low styrene content for emulsion graft copolymerization or with SAN resin in different proportions. Structure, properties and applications in the ABS resin, the rubber particles were dispersed, dispersed in the SAN resin continuous phase. When impacted, the crosslinked rubber particles take up and absorb this energy, dispersing the stress and thus preventing the development of the breach, thereby improving the tear resistance. The purpose of graft copolymerization is to improve the compatibility and adhesion of the rubber particle surface to the resin phase. This is related to the amount of free SAN resin and the SAN resin composition grafted onto the rubber backbone. The difference between the two acrylonitrile resin content should not be too large, otherwise the compatibility is not good, will lead to the cracking of the rubber and resin interface. ABS resin injection molding, extrusion, vacuum, blow molding and roller molding process for the plastic, but also machinery, bonding, coating, vacuum steaming and other methods of secondary processing. Because of its excellent overall performance, use more widely, mainly for engineering materials, but also can be used for household appliances. Because of its oil and acid, alkali, salt and chemical reagents such as good performance, and has electroplating, after plating the metal layer has good gloss, light weight, low price, can be used to replace some of the metal. Can also be self-extinguishing and heat-resistant type, and many other varieties, to adapt to a variety of purposes. Different material helmets have different properties, according to their needs to make the right choice.
