Mingyi Silicone(Anhui) Co., Ltd
【Composition】
Uncatalyzed fluorosilicone rubber based on fluorosilicone gum, and mixed evenly with some kinds of fillers and additives.
【Characteristics】
MY-R-C1000 is pale-yellow translucent fluorosilicone base.It has integrated advantages that both the silicone rubber and fluororubber have.
1. Its compression set is lower than normal ones of MY-R-M1000;
2. Wide application temperature range (-60℃~200℃);
3. Similar resistance to solvent &fuel oil to that of fluororubber;
4. Keeping high tensile force retention at high temperature which is like silicone rubber;
5. High insulation;
6.High selective permeability meets requirements of environmental protection.
Therefore it can be used as seal material in special condition with requirement of resistance to high and/or low temperature,oil and some other chemical mediums.

【Application】
1.Aviation industry:seals in aircraft to resist to fuels and/or lubricants,such as O-rings,spacers,integral tank sealing, sensor material,diaphragms and clips for spacers.
2.Auto industry:used as sealing rings,grease seals,diaphragms,pipes and valve-linings for various types of vehicles.
3.Petrochemistry industry:sealing parts used in pump,valve and oil tank,which are used under high/low temperature and chemical circumstance.
4.Medical and health care:used in manufacturing medical apparatus or instruments,artificial visceral organs,such as medical pipes,medical hoses for fluids and artificial valves.
5.Military industry:used in poor condition of environment,which requires material to resist to low temperature,oil and acid,for instance,corrugated pipes used in hydraulic system of military aircraft,sealing rods for doors,windows and covers on special vehicles,sensor material and etc.
