Rubber Material
Natural Rubber (NR)
A substance mainly composed of cis-polyisoprene found in the latex of rubber trees. It is formed by natural polymerization within living organisms. After collection, it is purified, coagulated, and dried to create raw rubber. Commonly used in products such as erasers.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent physical properties | Easy | No |
Nitrile Rubber (NBR)
A major type of synthetic rubber with excellent oil resistance, abrasion resistance, and tear strength. However, it is inferior to other rubbers in ozone and cold resistance. Commonly used in seals such as O-rings and gaskets, and in gloves.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent oil resistance | Easy | No |
Chloroprene Rubber (CR)
A synthetic rubber produced by polymerizing chloroprene. It surpasses natural rubber in weather resistance, heat resistance, oil resistance, and chemical resistance, and is easy to process. Used in O-rings, conveyor belts, rolls, risers, wetsuits, and cable coverings.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent heat resistance | Moderate | Yes |
Styrene-Butadiene Rubber (SBR)
This synthetic rubber offers excellent heat resistance, abrasion resistance, aging resistance, and mechanical strength. While its cold resistance and tear strength are lower than other general-purpose rubbers, it is widely used in automobile tires due to its stable quality and workability.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent abrasion resistance | Moderate | Yes |
Butyl Rubber (IIR)
A type of synthetic resin known for its exceptional stability under normal conditions. It is a transparent, impurity-free, non-toxic semi-solid polymer with high tackiness, making it suitable for use in adhesives.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Low gas permeability and excellent acid resistance | Easy | Yes |
Urethane Rubber (UR)
A high molecular compound also known as polyurethane. It offers high tensile strength, oil and abrasion resistance, but is less resistant to heat and water compared to other synthetic rubbers. It is also used in coatings, sponges, textile processing, and synthetic leather.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| High mechanical strength and excellent abrasion resistance | Easy | Yes |
Ethylene Propylene Rubber (EPDM)
A type of synthetic rubber known for its excellent ozone resistance. While it is not very resistant to oils and organic solvents, it is used in outdoor anti-vibration components, cable jackets, and playground equipment due to its non-toxicity.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent heat and acid resistance | Easy | Yes |
Fluoro Rubber (FKM)
Offers superior resistance to heat, oil, and chemicals, making it widely used in the automotive, semiconductor, and chemical plant industries. However, it is less resistant to some specific chemicals and has poor cold resistance compared to other rubbers.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent heat and chemical resistance | Difficult | Yes |
Silicone Rubber (Q)
Silicone rubber refers to the rubbery form of silicone resin. Known for its outstanding heat, water, and chemical resistance, it is widely used in medical applications such as elastic materials, molding agents, and textiles.
| Property | Flammability | Self-Extinguishing |
|---|---|---|
| Excellent heat and cold resistance | Easy | Yes |
