Types of Materials and Their Uses

What are the materials? Material can be living or non-living, pure or impure, or a combination of both. Materials can be classified based on physical and chemical properties, geological origin, and biological function. Listed below are some examples of materials.

Each has its own physical, chemical, and biological properties. For more information about a material, check out its Wikipedia entry. Also, consider the following list of common materials. Listed below are some uses for various materials.

Silicone Q MQ VMQ PVMQ

Silicones are synthetic elastomers composed of silicon and quartz, with pendant organic groups attached to the silicon atoms. Silicones are excellent elastomers due to their high resistance to ozone, UV, and weather, as well as their dielectric stability.

VMQ exhibits the best elastomeric properties at low temperatures, but it exhibits poor tensile strength and poor tear resistance.

There are several varieties of silicones. Each one has a different chemical structure and uses. MQ silicone contains vinyl groups, while PVMQ has phenyl groups. FVMQ contains trifluoro propyl groups.

This type is more expensive than MQ but it is often the preferred choice for medical and food handling applications. Silicone rubber has excellent thermal and compression resistance and is a good electrical insulator.

In addition to LSR, MQ is a two-component silicone rubber that can be used in injection molding. This material can be injected into molding tools with more than 200 cavities.

When the cavity is closed, thermal energy is applied to harden the contents of the closed molding tool. Silicone rubber is then extracted. However, the manufacturer of MQ should be aware of the differences between silicone Q and PVMQ.

Fluorosilicone FVMQ

Despite being similar to FKM, fluoro silicone has many advantages over its counterpart. These materials have excellent resistance to hydrocarbon and petroleum-based fuels while offering a higher service temperature.

Fluorosilicones are widely used in high-temperature fuel systems, although the material can also be exposed to hydrocarbon-based fuels. Moreover, while FKM can operate at a relatively high temperature, fluoro silicone has a much broader operating temperature range than FKMs. Additionally, they are much more resistant to low-temperature environments than FKMs, making them suitable for a wide range of applications.

Although fluorosilicone exhibits a range of properties, its mechanical properties remain constant over a wide temperature range. It is preferably used for diaphragms subject to dynamic loading.

Its low tensile strength, poor abrasion and tear resistance limit its application scope, but they still have many uses in automotive sealing. A typical application of fluorosilicone rubber is the static sealing of fuel systems. It is also used in turbocharger hoses and O-rings.

Despite these advantages, fluorosilicone is still not the right choice for every application. Although fluorosilicones are similar in chemical resistance, they have superior fuel and mineral oil resistance.

The material has poor heat resistance, but still offers excellent performance in high-temperature applications. In addition, it exhibits excellent thermal and chemical resistance. Compared to silicone, fluorosilicone does not deform under high stress or pressure.

Viton® FKM

Viton® FKM materials are ideal for high-temp environments and are resistant to a variety of chemicals and extreme temperatures. These materials are especially effective for hot environments, ranging from 200°C to 220°C.

Despite their weather-resistant nature, they do not degrade easily when exposed to sunlight, acidic biodiesel, or ozone. Moreover, they resist oxidation and tear, two key features that make them ideal for many industrial applications.

Developed to address the needs of the aerospace industry, Viton(r) fluoroelastomer has since found numerous other applications.

It was originally a trademark of DuPont Performance Elastomers and is now a generic term for fluoropolymer elastomers. Currently, Viton(r) is commonly used to manufacture O-rings, fuel system seals, hoses, and molded goods.

Chemours offers 25 different types of FKM polymers, based on their fluorine content, viscosity, and curing method. Higher fluorine content leads to better chemical resistance.

Lower viscosity polymers help mold flow. The curing mechanisms also affect the properties of the product. For example, Peroxide-cured compounds offer better chemical resistance, while Bisphenol-cured compounds provide better compression set resistance.

Because Viton O-rings are excellent for general-purpose applications, these elastomers are a great choice for high-temperature applications.

They offer excellent resistance to a range of chemicals, including oil and gas, and are highly resistant to ozone. These properties make them suitable for applications requiring general sealing, including hydraulic seals. So, what are the benefits of Viton(r) O-rings?

Buna-N/Nitrile NBR

Often referred to as “Buna-N,” a synthetic copolymer of acrylonitrile and butadiene is the most common type of O-ring in use today. Its composition varies from 18% to 50 percent acrylonitrile, with the more acrylonitrile the more resistant it is. Known for its outstanding mechanical performance, Buna-N is often used in applications that require exceptional strength, including automotive and marine fuel systems and disposable non-latex gloves.

Buna-N/NBR, also known as Buna-N, is a synthetic rubber polymer with excellent elasticity. Its properties make it ideal for O-ring seals, gaskets, and custom-molded components. This material is largely resistant to hydrocarbon fuels and petroleum-based oils and is used in a wide range of industries, including automotive and oil and gas.

Buna-N/Nitrile NPR possesses excellent dimensional stability and hardness. They are a popular choice for gaskets and O-rings in hydraulic and pneumatic systems, and in the oil and gas industry, where they can help dissipate high electrostatic charges. These synthetic elastomers are available in a B20 blend with 20 percent Bio-Diesel and 80 percent Petroleum Diesel.

Nitrile rubber is a general-purpose material resistant to a wide range of oils. It is the workhorse of oil sealing. Nitrile compounds come in different grades for fuels and industrial fluids. Most nitrile compounds can withstand temperatures up to 120 degrees Fahrenheit, although they are not recommended for glycol-based brake fluids or EP-type lubricants. In addition to nitrile, black NBR sheet is commercial-grade.

Neoprene CR

Neoprene CR materials are commonly used for a wide range of applications. These versatile materials are highly versatile and are used extensively in building adhesives and corrosion-resistant coatings.

They are also used in orthopedic braces, scuba diving wetsuits, and other waterproof products. But what is neoprene, and what are its uses? Let’s find out. Here are some of its uses:

CR has a wide temperature range and a moderate cost, making it an excellent choice for sealing applications that use refrigerants. Other benefits of CR include its resistance to water, ammonia, silicone oils, and ozone, although it has a low level of resistance to mineral oils and vegetable oils. For more information, contact ERIKS sealing and polymer. Here is a quick review of CR:

Chloroprene is a synthetic rubber that exhibits good chemical stability. It can be used in a wide range of temperatures and has a high level of elasticity. The examples summarized in Figures 11.6 and 11.7 show the results of various tests. Neoprene CR materials are highly flexible and exhibit good abrasion resistance. They are frequently used in laptop sleeves, electrical insulation, and automotive fan belts.

Neoprene is used extensively in industrial settings. Its durability makes it a desirable material for construction applications, particularly in the construction industry.

CR elastomers are highly resistant to heat, chemical, and ozone degradation, and have excellent compression and elasticity. They are also excellent choices for gaskets and O-rings. However, it is important to research the appropriate application before choosing any type of CR material.

Ethylene Propylene Rubber EPDM EPR

EPDM and EPR are two synthetic elastomers produced in large quantities. In the 1960s, the two products were not too far apart in production, but since then, production has increased to a record eighty-seven thousand metric tons annually. The production of EPDM and EPR are closely related. Both materials are used in tires, but EPDM has more uses than EPR.

The two materials are quite similar and can be used for a variety of applications. EPDM is a vulcanizate made from ethylene propylene and is the most common synthetic elastomer. It has a wide range of hardness and a molecular weight of twenty-five to fifty. High molecular weights and ethylene content improve the vulcanizate’s hardness.

EPDM is also known as ethylene-propylene rubber. This type of elastomer is a random copolymer made of two monomers, ethylene, and propylene. It can be used in a wide range of applications and is suitable for many different types of products. It also has a high flow and a high cure rate and can be blended with other polymers for enhanced ozone resistance.

EPDM and EPM are similar in composition. Both EPDM and EPM are made of ethylene, but EPDM contains fewer double bonds. They are both non-polar and contain small amounts of non-conjugated diene monomers that provide cross-linking sites for vulcanization.

EPDM is crosslinked only through a peroxide-based cure system. In some cases, the process of crosslinking can be done by irradiating the material with high-energy radiation.
