Zetpol® (HNBR) 의 소개 및 개요
산업분야의 종사자들은 금속처럼 강하고, 플라스틱처럼 가벼우면서 내화학성이 좋으며, 고무처럼 탄성이 있는 "Metaplastomer"라는 이상적인 물질을 생각하게 되었습니다. 자동차 산업, 에너지 산업 및 여러 다른 산업분야 개발자들은 어떠한 상황에서도 신뢰할 수 있고 내구성이 강한 "Metaplastomer"을 오랜기간 기다려 왔습니다. Nippon Zeon은 25년에 걸친 고무 사업의 경험을 기반으로 "Metaplastomer"와 가장 근접한 물성을 가진 Elastomer, Zetpol®를 개발하였습니다.
Zetpol®은 내유성이 강한 고무로 가장 범용적으로 쓰여왔던 NBR에 특별한 수소첨가 과정을 통해 생성되었습니다. 여기에 부가적으로 탁월한 내유성, NBR의 작업 용이성, 내열성, 내화학성 및 내오존성등의 기능을 확장시킨 제품입니다. 일반적인 내유 및 내열성 고무와 비교하여 Zetpol®은 인장력과 내마모성등의 훨씬 우수합니다. Zetpol®은 벨트, 실, 오일, 호스, 롤 등의 H-NBR 분야에서 선구적인 역활을 하고 있습니다. Zetpol®의 사용은 여러분에게 고무 분야에서 신뢰성과 견고성을 향상시켜드립니다.
Zetpol® Grade Availabilities
Increase of acrylonitrile content improves Zetpol's oil resistance but reduces its low temperature resistance, just like NBR in general.
As its degree of hydrogenation is increased (iodine value is decreased), its heat resistance is improved, but creep increases at the same time, and its rubber elasticity at low tempreratures is impaired.
Zetpol is highly compatible with PVC. Blending it with PVC produces a material with greater oil and ozone resistances. To enable you to put Zetpol to varous uses, Nippon Zeon is ready to offer several grades produced by various combinations of acrylonitrile content and iodine value.

General Propreteis of Zetpol®
Heat Resistance
Grades such as Zetpol® 1020 and 2020 with iodine values of 20~30 when sulfur cured, can be continuously used for 1,000 hrs at 125°C(257°F). On the other hand Zetpol® 2000cured with peroxide can be continuously used for 1,000 hrs at 160°C(320°F)
Oil Resistance and Brittle Temperature
With the same volume swell by oil, Zetpol® shows a lower brittleness temperature than NBR 5~7°C(9~13°F)
Tensile Properties
Zetpol® has higher tensile strength and wear resistance then NBR, to say nothing of the conventional heat, and oil resistant elastomers.
Application To Automobile Fuel Parts
Zetpol, while retaining the gasoline resistance, of NBR shows about five times higher sour gasoline and ozone resistances than NBR. Zetpol also has a lower birttle temperature than NBR displaying the same volume swell in gasoline. Compared with fluorinated rubber and NBR, Zetpol satisfies a wider scope of the properties required for fuel parts applications and permits larger cost saving than FKM. Accordingly, it is widely used for various fuel parts, including inner tubes of fuel hose which should assume a long service life. Especially suitable for this application are Zetpol 1020, 1010, and their blends with PVC.
Application To Belt
Zetpol is a suitale material for use a belt applicatin due to its excellent tensile strength, wear- and ozone-resistance. it's has a heat resistance 30'C(54'F) higher then CR and therefore enables the manufacture of high-temperature belts not producible with CR.
Its temperature dependency of dynamic modules is small, so it is especially ideal for producing synchronous belts which must transmit force quite accurately over a wide range of temperatures.
Especially suitable for this application are sulfur cured Zetpol 2020 & 2020L.
Application To Oil Line Parts
Recently, long life lubricants are becoming common. Several special additives in Tale1, some of which harm rubber materials, are added to these long life fluids. Due to the popularization of long life oil, the deterioration of rubber by sour oil with metal sludge has come to be noted. Zetpol shows little deterioration caused by these additives and sour oils.
It can also be designed with a high modulus and enormous tensile strength at high temperatures, making it ideal for use as a material for engine oil parts and hydraulic oil parts, as well as various kinds of oil hoses, oil seals, and packings.
Zetpol 2000, 2010, and 2020 are recommended for these applications.
NBR is severely harmed by detergents, antioxidants and anti-wear agents. ACM shows low tensile strength but is stable against the additives except alkyl phosphate and lead napthenate. FKM shows low strength like ACM but is deteriorated by succinic-imide, sulfurized olefine and alkyl phosphate. Zetpol is most stable, showing the highest tensile strength, against the additives but is changed slightly by zinc dithiophosphate.

Oil Well Application
With the increase of deep oil-wells, rubber materials with resistances to heat, hydrogen sulfide, corrosion inhibitor, steam and blister besides oil resistance have come to be strongly required.
Zetpol meets all these requirements, and also shows easy adhesion to metals and enormous tensile strength, making it an ideal material for blowout preventor, pipe protector, well head sealing, packing and other parts for oil wells.
Zetpol 2000,2010, and 2020 are normally used for these applications.
Other Application
In addition to displaying oil resistance comparable to that of NBR, Zetpol has an excellent resistance against chemicals, steam, wear, and heat.
Accordingly, it is ideal for industrial products normally made of NBR, such as various kinds of industrial rolls, including iron rolls and printing rolls, and various kinds of O-ring, packing, and gaskets.
These Zetpol products can be used under severest conditions and with much longer service life expectancies.
In addition, the processing method of Zetpol is fundamentally the same as that normally applied to NBR, so nosecial facilities are required.
NBR is severely harmed by detergents, antioxidants and anti-wear agents. ACM shows low tensile strength but is stable against the additives except alkyl phosphate and lead napthenate. FKM shows low strength like ACM but is deteriorated by succinic-imide, sulfurized olefine and alkyl phosphate. Zetpol is most stable, showing the highest tensile strength, against the additives but is changed slightly by zinc dithiophosphate.
