Rubber outsole and TPR outsole are different from each other in terms of recycling, characteristics, environmental protection and wear resistance.
1、 Difference from the perspective of recycling
The rubber outsole is higher than the original, and the rubber cannot be recycled.
TPR sole has low cost and can be recycled.
2、 Differences from the perspective of characteristics
The rubber sole is heavy, easy to defrost, acid and alkaline resistant. The appearance is not very decorative.
TPR sole has small proportion, light material, good elasticity, easy coloring and good air permeability. Commonly used in leather shoes and children's sports shoes, fashion shoes.
3、 Differences from the perspective of environmental protection
Rubber sole is a kind of high molecular compound, which can be divided into natural and synthetic rubber. It can't protect the environment.
TPR is a new environmental protection material, so TPR sole is environmental protection.
4、 Differences from the perspective of wear resistance
Rubber sole is a kind of high molecular compound, including natural and synthetic rubber. Common rubber outsole has soft hand feel, good elasticity and good wear resistance.
TPR sole, heavy material, poor softness, no rubber sole wear-resistant.
Synthetic rubber is divided into wear-resistant rubber, environmental protection rubber, air rubber, viscous rubber, hard rubber and carbon rubber.
(1) Wear resistant rubber: the wear resistance and toughness of wear-resistant rubber are very good, so it is very durable. This rubber material is generally used on the outsole of tennis shoes.
(2) Environmentally friendly rubber: also known as recycled rubber, this rubber outsole contains up to 10% recycled rubber, mainly for environmental protection.
(3) Air rubber: the rubber contains air and has certain shock absorption function, but it is not very wear-resistant and not widely used.
(4) Sticky rubber: sticky rubber is characterized by good flexibility, and very antiskid, generally used in indoor sports shoes.
(5) Hard rubber: hard rubber is the most comprehensive rubber in the rubber material of the outsole. It is tough, antiskid and wear-resistant, and has a wide range of uses. Multi functional shoes and basketball shoes are mostly made of this rubber.
(6) Carbon rubber: carbon element is added to ordinary rubber materials to make the rubber more durable and wear-resistant. This kind of rubber is mostly used in running shoes, and BRS letters are left on the back part of the sole of running shoes to indicate that carbon rubber is used in the outsole.
TPR refers to the reduction of catalyst in the process of temperature programmed. It can provide information about the interaction between metal oxides or between metal oxides and supports in the reduction process of supported metal catalysts.
A pure metal oxide has a specific reduction temperature, which can be used to characterize the properties of the oxide. If another oxide is introduced into the oxide and the two oxides are mixed together, if the reduction temperature of each oxide remains the same during the TPR process, there is no effect on each other.
On the contrary, if the solid-state reaction of the two oxides occurs and the properties of the oxides change, the original reduction temperature will also change. This change can be observed by TPR method.
