- NBR is the most widely used elastomer in the seal industry today.
- Good resistance to low temperature.
- NBR is often necessary to sacrifice some high temperature resistance.
- The working temperature range is considered to be -35°C to +120°C (-30°F to +250°F).
- Good tear, and abrasion resistance.
- NBR resists oil-based hydraulic fluids, fats, animal and vegetable oils, flame retardant liquids, grease, water, and air.
- Special low-temperature compounds are available for mineral oil-based fluids.
- Poor resistance to ozone, sunlight, or weather. They should not be stored near electric motors or other ozone generating equipment.
- By CR, Hypalon, or PVC blending, the NBR can meet a more specified range of physical or chemical requirements.
氯丁乙二烯橡膠 CRChloroprene Rubber, Neoprene
- 氯丁乙二烯橡膠(CR)是最早開發的合成橡膠並被廣泛運用在密封類產品
- 耐臭氧及耐候性佳, 長期暴露屋外也不劣化
- 不大耐芳香族碳化氫或鹵素碳化氫及氧化性藥品, 對其他藥品的抵抗性通常比NR和SBR安定
- 耐熱性良好, 110°C 以內耐長期使用, 不連續使用可耐到 120°C, 耐低溫可達-40°C
- 以CR為基質的接著劑有很強的接著力
- 耐油性僅次於NBR
- 有不自燃特性
- 因有極性基, 電絕緣性不如NR, IIR, SBR等, 但耐候性, 耐油性等優點, 可應用於低電壓用(600V 以下)的電線, 電纜保護層
- 缺點是原料橡膠儲藏安定性差, 耐寒性不如一般用橡膠, 但可由配方調整改善達到需求
- CR was the earliest synthetic rubbers used to produce seals.
- CR has good aging characteristics in ozone and weather environments, along with abrasion and flex cracking resistance.
- CR is not effective in aromatic and oxygenated solvent environments.
- The working temperature range is considered to be -40°C to +110°C.(-40°F to +230°F) But for short working periods it will take even 120°C.
- Good gasoline resistance.
乙烯丙烯橡膠 EPM, EPDMEthylene Propylene Rubber
- EPM / EPDM的溫度範圍為-50°C至+ 120°/ 150°C（-60°F至+ 250°/ 300°F），具體取決於固化系統
- 耐煞車油
- 對極性溶劑(醇, 酮, 乙二醇), 微酸鹼, 苛性鈉等無機藥品很安定
- 缺點是接著性不佳, 耐油及耐龜裂性差
- EPM/EPDM has a temperature range of -50°C to +120°/150°C (-60°F to +250°/300°F), depending on the curing system.
- Good resistance to brake fluid.
- It has a great acceptance in the sealing world because of its excellent resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight.
- EPM/EPDM compounds are not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments.
矽(硅)橡膠 VMQSilicone
- 矽酮化合物非常乾淨，廣泛使用於很多食品和醫療用品上. 觸感極佳, 亦廣泛用於電子產品及按鍵類產品
- 特殊料可用於導電, 防火材質
- 適用溫度範圍大, 電氣性質變化少, 無臭無味
- 適用溫度範圍: -50°C 到 232°C (-58°F 到 +450°F). 物性變化很小, 高溫下其物性優於一般彈性體, 低溫也不失彈性
- 特殊料可到達 -60°C到 300°C 的使用範圍. PMQ,PVMQ有優秀的耐寒性(-73°C~-90°C)
- 耐臭氧性, 耐候性優
- 除固態矽橡膠料(過氧架橋), 另外有液態(糊狀)之原料以白金架橋方式成型, 可供低溫成型, 甚至可室溫成型
- 缺點是耐磨耗性, 抗拉, 抗撕裂強度差
- 耐化學藥品性不佳, 原料價格高
- Moderate physical properties but are retained at high or low temperatures.
- Good electrical properties and good ozone resistance.
- The working temperature range is considered to be -50°C (-58°F) to +232°C (+450°F).
- PMQ, PVMQ have even lower low-temperature resistance (-73°C~-90°C).
- Low tear strength and poor abrasion resistance.
- Poor oil, and poor chemical resistance.
氟化矽橡膠 FVMQFluoro-silicone
- 有優秀的耐油, 耐溶劑, 耐藥品性, 及耐寒性
- 適用溫度範圍: -73°C (-100°F) to 200°C (390°F)
- 缺點是價格偏高
- Fluorosilicone combines the good high- and low-temperature properties of silicone with limited fuel and oil resistance.
- FVMQ provide a much wider operational temperature range than Fluorocarbon rubbers.
- The working temperature range is considered to be -73°C (-100°F) to 200°C (390°F).
- FVMQ O-rings may also be exposed to petroleum based oils and/or hydrocarbon fuels.
- Due to relatively low tear strength, high friction and limited abrasion resistance of these materials, they are generally recommended for static applications only.
- FVMQ with high tear strength are also available. Some of these compounds exhibit improved resistance to compression set.
- Disadvantage: too expensive.
