Tread reclaimed rubber with high content of plastic, high strength, often used in the production of wire and cable skin. The use of tread reclaimed rubber production of wire and cable sheath, in order to improve its performance, improve the tear strength of wire and cable sheath and flex resistance performance, within the cost allowable range, the best use of tread reclaimed rubber and natural rubber And with the way.
The use of tread reclaimed rubber and natural rubber used in conjunction with the production of wire and cable sheath when the need to pay attention to the following questions:
1, the wire and cable sheath tear strength, flex resistance and elongation at break will increase with the increase of natural rubber dosage, the aging resistance and electrical insulation properties will increase; Therefore, by adjusting the proportion of natural rubber blend to improve the performance of the skin reclaimed rubber wire and cable sheathing.
2, there is data shows: tread reclaimed rubber and natural rubber mixed with a ratio of 1: 4, the resulting wire and cable sheathing performance and all-natural rubber products produced the closest performance, so if the cost allows, the tread Reclaimed rubber and natural rubber mixed with the best control in the ratio of about 1: 4.
3, the tread reclaimed rubber and natural rubber used in conjunction with the production of wire and cable sheath, the mixing ratio of the two is not static; in order to better reduce costs, rubber products manufacturers can be based on their own wire and cable skin product grades, performance, Index requirements, will be mixed with the proportion of adjusted to meet their own national product standards can be.
4, tread reclaimed rubber product quality is good, you can properly reduce the amount of natural rubber doping.
The use of tread reclaimed rubber and natural rubber production of wire and cable sheath can significantly reduce the cost of raw materials (tread reclaimed rubber price is about 1/4 the price of natural rubber), but also improve the anti-aging properties of rubber products to extend the service life of Really serve multiple purposes.
The raw material of the tread reclaimed rubber is used tire tread rubber powder. Compared with other parts of the tire reclaimed rubber, the rubber content is higher and the wear resistance is better. It can be well integrated with the natural rubber when replacing part of the natural rubber production wire and cable sheath. Together, it can significantly reduce the cost of raw materials without affecting the processing technology and product quality; wire and cable sheathing is a typical extruded rubber product. When choosing a tire tread reclaimed rubber, choose a high cost under the conditions permitting The fineness of the product ensures that the wire and cable jackets are smoothly extruded and the surface of the products is black and shiny.
