Shenyang rubber insulation kraal pad: tell me about rubber products of 'past'
Rubber products can be seen everywhere in life, all kinds of rubber products because of different varieties of different characteristics also.
In this paper, shenyang rubber insulation kraal mat for you about the 'past' of rubber products.
Rubber seal products commonly used materials as follows.
Nitrile rubber fuel oil and aromatic solvent resistant performance is good, but not resistant to ketones, esters and chlorinated hydrocarbon, such as medium, so mainly adopts the nitrile rubber oil seal products.
And oil resistance of NBR increase with the increase of acrylonitrile content, but high content of acrylonitrile in nitrile rubber cold resistance is poor.
Fluorine rubber has the outstanding heat resistance (
Resistance, oil resistance, is widely used in the manufacture of cylinder sleeve sealing ring, plastic bowls and axis lip seals.
Silicone rubber high and low temperature resistance, resistance to ozone and weather aging performance is outstanding, in -
The working temperature of 70 ℃ ~ + 260 ℃ can keep its unique use of elastic and ozone resistance, weather resistance and other a bit, but it is not resistant to oil.
Polyurethane rubber abrasion resistance and permeability is good, its temperature range is commonly -
In addition it medium oil resistant, resistance to oxygen and ozone aging properties, but polyurethane rubber is not resistant to acid and alkali, water, steam and ketone, etc.
Acrylate rubber of mineral oil, lubricating oil and fuel oil is good, especially under the high temperature of oil is very stable, generally can reach 175 ℃, clearance to use more than 200 ℃ or a short period of time can be oil resistant.
But its cold resistance is poorer.
With the continuous application of science and technology, rubber kraal pad material gradually varied.
All kinds of rubber material has the characteristics of different, understand its characteristics more conducive to our purchase and use.
Each rubber has its own advantages and disadvantages, therefore, shenyang rubber insulation kraal pad small make up in this unit you will learn about rubber tip enterprise features, and then you can according to their own production needs targeted to choose and buy.
