I believe that many friends who work in the rubber industry all the time should have heard of "PP reclaimed rubber," which is the isoprene reclaimed rubber that Xiaobian said today. All along, isoprene reclaimed rubber is a unique presence in reclaimed rubber products. Like isoprene rubber, it is neither a natural rubber nor a synthetic rubber but has the properties of natural rubber and synthetic rubber. The following characteristics of the isoprene reclaimed rubber are followed along with Xiao Bian.
1, isoprene reclaimed rubber performance characteristics
Compared with natural rubber, isoprene possesses excellent elasticity and flexibility of natural rubber, but its product itself has higher fineness, less impurity content, better abrasion resistance, heat resistance, aging resistance, and chemical stability than natural rubber. Better; Isoprene reclaimed rubber is more elastic than synthetic rubber and can be combined with natural rubber and general synthetic rubber. The use of an appropriate amount of isoprene reclaimed rubber in bicycle tires can significantly improve the abrasion resistance, puncture resistance, and softness of the rubber compound.
2, isoprene processing performance characteristics
When using isoprene reclaimed rubber to produce rubber products, the vulcanization speed is stable, the plasticizing time is short, and the mixing is easy; the reclaimed rubber has good fluidity, and rolling, extrusion, molding and other operations are easier; however, due to isoprene The ene regenerated gum is very soft, and its inherent stiffness is poor, so the rubber compound is prone to deformation during storage, and it is difficult to install the mold in the subsequent processing. The manufacturer of the rubber product must make corresponding countermeasures.
3, isoprene reclaimed rubber use
From the color point of view, most of isoprene reclaimed rubber on the market is grayish or light gray solid, so it can be used for various light gray rubber products, and the color matching is easy and discoloration is not easy to occur.
Isoprene reclaimed rubber is the most widely used rubber product to replace natural rubber to produce rubber products, such as tires, hoses, tapes, rubber shoes, etc. It can not only reduce the cost of raw materials, but also improve the high and low temperature resistance and aging resistance of rubber products. Extend the service life of rubber products. At the same time, PP reclaimed rubber can also replace rubber materials such as chloroprene rubber and butyl rubber to improve the processing properties of rubber, and to produce adhesives, caps for medical caps, and sheaths for electric cables and wires.
