Bicycle tire tread rubber is required to have good wear resistance, fatigue resistance, aging resistance and high elasticity, tensile strength, toughness, etc. Generally, natural rubber or natural rubber and styrene-butadiene rubber and butadiene rubber are used in combination. processed. The main components of tire reclaimed rubber processed from waste tires are natural rubber, general-purpose synthetic rubber and carbon black. In plastic, the cost of raw materials can be effectively reduced on the premise of ensuring product quality.

When using tire reclaimed rubber to reduce the production cost of bicycle tire tread rubber, it is generally recommended to use tire tread reclaimed rubber, which is processed from waste tire tread rubber powder 2ELYY415 raw material. It has high effective rubber hydrocarbon content, high strength, good elasticity, and wear resistance. , tear resistance, can appropriately increase the amount of tire reclaimed rubber, reduce more raw material costs and save electricity costs on the premise of ensuring product quality. In the follow-up, the editor will continue to share with you the production process skills of bicycle tire tread rubber mixed with reclaimed rubber.
