As an important material to protect wires and cables from the external environment, cable sheath plays a vital role in the power industry and communications. With the enhancement of environmental awareness and the increasing importance of resource recycling, the use of EPDM recycled rubber powder has become a new way to reduce the cost of cable sheath. The replacement of traditional EPDM rubber powder with EPDM rubber has obvious cost-effective advantages, and has high practical value for improving the market share of products.
EPDM recycled rubber powder is made by sorting, cleaning, crushing and regenerating waste EPDM rubber, and has the following characteristics:
1. Low cost. Compared with traditional EPDM rubber, the price is lower, which can effectively reduce the cost of raw materials.
2. The specific gravity is light. Compared with the specific gravity of light calcium carbonate added to traditional EPDM rubber, the specific gravity of EPDM recycled rubber powder is lighter, which reduces the density of the product and reduces the weight of the cable sheath while ensuring strength and performance.
3. Good wear resistance. Since ethylene propylene recycled rubber powder contains some carbon black and additives, the wear resistance of the cable sheath is improved, which can better protect the wire and cable from external friction and damage.
to improve cable jacket performance with EPDM recycled rubber powder
Mixed with Hongyun EPDM recycled rubber powder to produce cable sheath reference vulcanization formula:
60 parts of EPDM recycled rubber powder, 20 parts of EPDM rubber, 1 part of N550 carbon black, 30 parts of rubber reinforcing agent, 1 part of gumaron, 15 parts of paraffin oil, 0.5 parts of polyethylene glycol, 0.5 parts of stearic acid, 2 parts of sulfur, 1 part of vulcanization accelerator, and an appropriate amount of foaming agent. The vulcanization temperature is about 165 °C, and the vulcanization time is self-adjusted.
The low-cost formula of using EPDM recycled rubber powder YYE3-803 to produce cable sheath has the characteristics of low cost, light specific gravity and good wear resistance. Through reasonable vulcanization formula and processing technology, we can produce cable sheaths with superior performance, reduce raw material costs and reduce waste of resources, which not only meets the market demand for low-cost and high-performance products, but also improves the market competitiveness of products, laying the foundation for opening up a larger rubber market.
