Rubber bottom (RB)
As the name s ests, is made of rubber soles. Rubber sole material may be divided into natural rubber or synthetic rubber.
RB is the abbreviation of English Rubber (rubber), hot pressing and plastic forming, natural rubber and reclaimed rubber. Heavy weight, not oil, the end of the mold must be in the joint surface grinding, easy to shorten the heating time, color is inconsistent.
Advantages: good abrasion resistance, anti slip, elastic, not easy to break, good softness, good stability, extended shrinkage, good hardness, good flexibility, waterproof.
(1) natural rubber
The advantage of natural rubber is that it is very soft, good elasticity, and can be adapted to various kinds of sports, but the disadvantage is that it is very not wear. Indoor sports shoes with natural rubber.
(2) artificial synthetic rubber
Synthetic rubber is divided into wear-resistant rubber, rubber, rubber, rubber, rubber, hard rubber, rubber, rubber.
A. wear resistant rubber
Wear resistance and toughness are very good, so very durable, this kind of rubber material is generally used in the big end of the tennis shoes.
B. green rubber
Also known as the recycling of rubber, rubber, which contains up to 10% of the rubber, the main purpose is to protect the environment.
C. air rubber
Rubber containing air, has a certain shock absorption function, but not very wear-resisting, use is not very wide.
D. viscous rubber
The characteristics of viscous rubber is good flexibility, and very slippery, generally used in indoor sports shoes.
E. hard rubber
Hard rubber is the most comprehensive rubber material, the most comprehensive rubber, tough and non slip resistant and wear-resistant, natural and very wide range of uses. More functional shoes and basketball shoes are mostly used in this kind of rubber to expand the bottom.
F. plus carbon rubber
Adding carbon in the ordinary rubber material, the rubber is more durable, mostly using the rubber shoes, and will leave a BRS letter in front part of shoes soles, to use carbon rubber outsole.
