How to Choose VMQ,SILICONE and FVMQ?

Content Menu

1. Introduction

VMQ/SILICONE and FVMQ are two elastomeric materials that are used a lot in many industries, from automotive seals to aerospace equipment, where they are very important. But it’s not always easy to choose the right material for different weather conditions. For example, some seals in car engines have to be able to handle being exposed to high temperatures, oil, and chemical corrosion for a long time. FVMQ often works better than VMQ/SILICONE in these kinds of tough situations. For most household appliances, though, VMQ/SILICONE may be more than enough. This raises an important question: how do we pick the best material for different uses? Next, we’ll look at the main things that affect this choice.

2. Performance Comparison: VMQ vs. FVMQ

1. Temperature Resistance:

– FVMQ: The highest temperature it can work at is 200°C, and the lowest temperature it can work at is -80°C.

– VMQ: The highest temperature it can work at is 250°C, and it can work in temperatures as low as -70°C and as high as -120°C.

VMQ works better at high temperatures, but both work the same at low temperatures. However, VMQ has a wider low-temperature range.

2. Chemical Resistance and Stability :

– FVMQ: It is very resistant to fuels, oxygen, oils, and chemical solvents, especially in chemical solvents and fuel oils.

– VMQ: It doesn’t break down as easily in solvents as FVMQ does, but it does resist oxygen and chemicals well.

FVMQ is better than VMQ at keeping chemicals, fuel oil, and combustion stable.

3. Mechanical Properties: Elasticity, Hardness, and Abrasion Resistance:

– FVMQ: It is flexible and has a hardness range of 50 to 80 Shore A, but it doesn’t hold up well to wear and tear.

-VMQ: It also has great elasticity, but its hardness range is wider, from 30 to 90 Shore A, and its ability to resist abrasion is a little weaker.

VMQ has a wider range of hardness options than both materials, but they are both equally elastic. When it comes to resisting wear and tear, both do okay, but FVMQ is a little better than VMQ.

4. Aging Resistance:

-FVMQ: Has great resistance to aging, ozone, and oxygen.

– VMQ: Also has a lot of resistance to aging, especially when exposed to heat, oxygen, and ozone.

Both materials are very resistant to aging, making them good for uses that need to be in harsh environments for a long time.

 3. Application Scenario Analysis

1. How well it works in different applications:

VMQ and FVMQ are both useful in their own ways in their own fields. VMQ is often used in situations where you need long-term high-temperature, low-temperature, and good electrical insulation, like for seals, insulation layers for wires and cables, and food-grade and medical-grade seals. VMQ is also used a lot in things that touch food and people because it doesn’t smell or hurt people.

FVMQ, on the other hand, is great for sealing and protecting parts in very harsh conditions, like in the aerospace and automotive industries. When exposed to fuel oils, lubricants, hydraulic oils, and other oil products, it can stay elastic and stable for a long time. This makes it perfect for oil tank seals, automotive oil seals, diaphragms, and other oil products.

2. Case Studies:

– VMQ (Silicone Rubber):

    – Food and Medical Equipment Industry:

      In food processing equipment, VMQ seals are very common in food processing equipment because they can handle high temperatures, are safe to use, and don’t smell. They can work in steam environments for a long time without changing the taste or safety of the food. VMQ seals can work for long periods of time at 200°C in high-temperature baking equipment without losing much performance.

– Medical Equipment:

     VMQ is the best material for medical devices like respiratory masks and catheters because it is biocompatible and doesn’t break down when cleaned. It can handle repeated high-temperature disinfection treatments without losing its softness or sealing ability.

    – Electronics Industry:

      In the electronics industry, VMQ is used in the electronics industry to make insulating materials like high-temperature cable sheaths. It works well in high-temperature electrical environments because it can handle heat and is a great electrical insulator. For example, the VMQ insulation layer in electrical equipment can work at 250°C, which keeps the equipment running normally.

– FVMQ (Fluorosilicone Rubber):

    – Aerospace Industry:

      FVMQ is widely used in the aerospace field. For instance, FVMQ seals in an aircraft’s fuel system can keep their sealing ability even when the temperature changes a lot (from -60°C to 200°C), resist corrosion from fuel oil, and stop fuel from leaking. A common example is the fuel system of a certain type of passenger plane. After years of use, FVMQ seals have kept their great elasticity and oil resistance, which means that they don’t have the problems with material aging and fuel leakage that regular rubber does

    – Automotive Industry:

     FVMQ is used to make important seals in the automotive industry, like engine oil seals and fuel system seals. FVMQ can withstand the high temperatures and chemical erosion of engine oil, which makes seals last longer. FVMQ is often used as an oil seal material in high-performance racing cars because it is resistant to oil and high temperatures, which keeps the engine running normally running of the engine.

    – Oil and Chemical Industry:

     FVMQ is used in the oil and chemical industries to seal and protect oil pipelines and chemical containers so they don’t corrode and keep working well at high temperatures. For instance, FVMQ seals work very well to keep the reactor system in a chemical plant tight during chemical reactions and prevent leaks and other safety problems.

4. Cost

1. Cost Comparison:

– VMQ: VMQ is usually less expensive and comes in a variety of forms to fit different budgets and performance needs.

– FVMQ: FVMQ is usually more expensive because of its special performance features, which include its unique resistance properties and its use in high-performance applications.

 5. Selection Recommendations

1. Recommendations Based on Application Needs:

– Choose VMQ:

    – You need materials that can withstand high temperatures for things like electrical insulation or food-grade materials.

    -Price is a big deal, and the environment doesn’t need things that can resist a lot of chemicals or oil.

– Choose FVMQ:

    -Involves being around harsh chemicals, fuels, or very high or low temperatures.

    – Material that can work well in cars and planes.
