Type of Rubber Materials for Custom Rubber Seals & Gaskets

In rubber manufacturing, dozens of materials are available for selection. Which material is the most suitable for your seals, gaskets, parts, or components? Don't worry. The following information on rubber material properties gives customers a broad overview of different rubber properties to aid in selecting rubber for particular service conditions.


Rubber Materials Material Introduction Material properties
EPDM rubber material EPDM rubber is a highly durable synthetic rubber material with excellent electrical insulation properties. It is used extensively in automotive seals, hoses, tubing, washers, belts, o-rings, and moisture seals. Strong and durable, with good anti-aging performance;
Outstanding resistance to weathering, ozone, and heat.
Silicone rubber material Silicone rubber is a synthetic material. It has excellent high-temperature resistance, enabling it to perform well in extreme heat conditions. Additionally, it offers great flexibility and chemical resistance, making it suitable for a wide range of applications. Silicone rubber is widely used for automotive, aerospace, and medical devices like gaskets and tubing. Environmentally friendly and safe, with good insulation
High and low-temperature resistance, UV resistance
Soft and comfortable, various colors
Neoprene rubber material CR, is a synthetic rubber also known as polychloroprene. Neoprene exhibits good chemical stability and remains flexible over a wide temperature range, making it suitable for various applications, such as wire sheathing, hoses, heat-resistant conveyor belts, etc. Strong resistance to oils, oxidation, ozone, and flame.
Great waterproof performance
Acid and alkali-resistant
Good bonding
Viton rubber material It is a high-performance elastic material, also known as FKM. Its excellent properties include high-temperature resistance, chemical corrosion resistance, aging resistance, and oil resistance. It has been widely used in aerospace, automobiles, petroleum, and household appliances, like o-rings, seals, gaskets, diaphragms, tubing, and more. High-cost synthetic rubber
Good fuel and oil resistance
High-temperature resistance
Acid and alkali resistance
Resistant to a variety of chemicals
Natural rubber material Natural Rubber (NR) is usually extracted from the latex of oak trees. It mainly comprises monomers such as isoprene and styrene and has good elasticity, wear resistance, and tensile strength. It is widely used in automobile tires, soles, medical equipment, and building sealing materials. Excellent elasticity
High strength
Excellent comprehensive performance
Wide range of applications
Nitrile rubber material It is a synthetic rubber known as NBR rubber (nitrile butadiene rubber). It has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. Its disadvantages are poor low-temperature and ozone resistance, poor insulation performance, and slightly low elasticity. It is mainly used to make oil-resistant rubber products. Good oil resistance
High wear resistance
Airtightness
Poor low-temperature resistance
Butyl rubber material Butyl rubber (IIR) is a synthetic rubber. It has outstanding impermeability to air and moisture, making it ideal for applications like inner tubes and seals.  Resistance to fats, oils, greases, ozone, and strong/oxidizing chemicals. It also provides strong shock absorption capabilities. Great for handling your shock/vibration and durability parts. Strength, flexibility, and low gas permeability
Excellent chemical resistance, able to withstand a variety of chemicals
Shock absorption and durability
Synthetic rubber material Synthetic rubber, called Styrene Butadiene Rubber (SBR), is a cost-effective and versatile material. Although it is not resistant to oil, it provides a reliable alternative to natural rubber with consistent quality and availability. It offers enhanced resistance to heat, abrasion, and chemicals. Moreover, synthetic rubber is more economical than natural rubber and can be customized to meet different needs. Similar elastomer to natural rubber, low-cost
Versatility
widely application
Low-temperature flexibility
Excellent heat resistance
