Analysis on the performance of EPDM rubber sheet
Compared with ordinary rubber sheet, EPDM rubber sheet is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene, which is a kind of ethylene-propylene rubber.
With the progress and development of various industries, the variety of rubber sheets is increasing, and the performance of rubber sheets has been improved. Among them, the EPDM rubber sheet is a new type of rubber sheet that has been improved in all aspects. The following briefly introduces the characteristics of the EPDM rubber sheet.
1. EPDM rubber sheet is the most commonly used rubber with the lightest density of raw rubber. The density is only 0.86 to 0.90 kg / m³, and it can be filled in large quantities to reduce the cost of rubber materials. The product is extremely cost-effective.
2. The insulation performance is very good, the volume resistivity is 1016Q · cm, the breakdown voltage is 30 ～ 40MV / m, and the dielectric constant is 2.27. The minimum operating temperature is about -40 to -60 ° C, and it can be used normally even at 130 ° C for a long time. EPDM rubber sheet can be used in a wide temperature range and can be used under different temperature conditions.
3. When the EPDM rubber sheet is used together with other unsaturated diene rubber, the EPDM rubber sheet can play the role of high molecular antioxidant and anti-aging. With weather resistance, ozone resistance, sun protection, anti-radiation, anti-aging, and other properties.
4. EPDM rubber sheet has excellent chemical resistance, and the product has excellent water resistance, superheat resistance, water vapor resistance, and polar oil resistance.
To sum up, the above four points have introduced the performance of the EPDM rubber sheet in detail. Compared with the traditional rubber sheet, this new type of rubber sheet has great advantages. EPDM rubber sheet not only has excellent performance but also has the high-cost performance. At present, the EPDM rubber sheet is widely used in various industries.
