1. HNBR imported O ring
O type ring physical properties of hydrated Ding Qing import:
The high temperature resistance of HNBR is 130~180 C, the cold resistance is -55 to -38 C and the mechanical properties are excellent. Compared with other polymers, it can meet the requirements of the automobile industry more. HNBR with ZnO/ MAA reinforcement can be used to make triangle belt, equal gauge triangle belt, multi-purpose triangular ring bottom rubber, vibration isolator, etc., and seal rings, seals and heat-resistant pipes can also be prepared. In oil drilling well, it is required that rubber products must withstand the test of high temperature, high pressure, acid, amine, H2S, CO2, CH4 and other steam. The products made with HNBR can be acid resistant, oil resistant and solvent resistant. With the ZnO/MAA HNBR reinforcement can be used for the production of drilling mud pump piston and protection box. In addition, the beating method HNBR can be used as a sealing washer washer made of paper oil industry and automobile industry. HNBR heat and radiation resistance properties than silicon rubber, fluorine rubber, poly four vinyl chloride is better, suitable for all kinds of rubber seals for power station, is also used as a hydraulic pipe, hydraulic seals, power station for cable sheath, can also be used for printing and fabric roller, weapons components and aerospace seals, cover, fuel capsule; HNBR latex can be used as a surface coating (painting), textile, paper, leather, metal, ceramic fiber, non-woven adhesive, and foam rubber, latex impregnated products etc.. In addition, the comprehensive performance of HNBR with ZnO/MAA, peroxide and high wear-resistant furnace is better than that of ordinary HNBR.
Two, the advantages and disadvantages of HNBR import O ring:
1/ is not resistant to hydrogen, and is not suitable for ultraviolet, oxygen and ozone. But its poor weatherability can be improved by special additives.
2/ natural rubber seals general performance:
The long-term working temperature of 3/ is -40 C ~150 C, and the limit temperature can reach 160 C in a short time. The general hardness of the seal is between A40 and 90 degrees. The common hardness is generally 70 degrees, and the other hardness is calculated according to the pressure that your matrix has.
The design of 4/ natural rubber industry is very broad, excellent tear resistance, abrasion resistance, flex resistance, impact resistance, water resistance, good insulation, plasticity, water vapor barrier and so on outstanding performance in the industry, agriculture, national defense, traffic, transportation, machinery manufacturing, medicine health and daily life applications are very extensive, and the seal of our production is mainly used in industrial field.
The basic performance of three and HNBR imported O ring
Advantages: good heat resistance, curing material of organic peroxides can be used continuously for 1000 hours at 160 degrees Celsius in air, and NBR at 150 DEG C, will lose the value of continuous use; excellent oil resistance, oil resistance and alcohol based fuel properties are much better than that of NBR and NBR/PCV blends corresponding; low temperature resistant performance is better than that of NBR; ozone aging the performance and resistance to various media (water, acid, alkali, alcohol) outstanding performance. Its mechanical properties are also superior to ordinary NBR, and have better corrosion resistance, tensile resistance, tearing resistance and compression resistant permanent deformation.
Temperature: -55~160 degrees -40~150 C
The hardness of A50-90 degrees commonly used 60-75 degrees
Color: red, transparent, white, other colors can be customized (food level with transparent, other temporarily not for sale)
