Li tou apwopriye divès kalite atik ke com nan kontak ak imen kò a kò dlo dlo 2c dlo dispansè, Li li rekòmande pifò pifò konsantre solvay 2c lwil oliv, konsantre asid, ak sodium hydroxide. The general tanperati ranje !7b{1}}}}}}% degre .
4, VITON fluororubber sealing ring: It has better high-temperature resistance than silicone rubber, excellent weather resistance, ozone resistance, and chemical resistance, but poor cold resistance. It has resistance to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. Suitable for sealing requirements of diesel engines, fuel systems, and chemical plants. It is not recommended to use in ketones, low molecular weight esters, and mixtures containing nitrate. The general temperature range for use is -20~250 degree .
5, FLS fluorosilicone rubber sealing ring Lis Pèfòmans avantaj fluorosilicone rubber ak silicone kawotchou rubber, ak ekselan rezistans rezistans, solvay rezistans, fuel rezistans, ak segondè ak ba tanperati rezistans. Li ka reziste erozyon oxygen-ki gen compounds, solvay ki gen aromatic hydrocarbons, ak solvay ki gen chlorine. Jeneralman itilize avyasyon, aerospace, ak militè rezon. Manifaktirè of rubber rubber coils rekòmande rekòmande ketones brake jeneral tanperati ranje !7b2{2}}}}% degre .
6, EPDM EPDM sele ring: Li move tan rezistans, ozone rezistans, dlo rezistans, ak pwodui chimik Li alkòl ak ketones, sele sele -tanperati vapor environments. Apwopriye twalèt ekipman radyatè% radyatè% machin brake systems. rekòmande manje ekspoze mineral jeneral tanperati 7b2{2}}~150 degre .
7, CR chloroprene kawotchou sele ring Li gen ekselan rezistans sunlight weather. afrijerants nan frigerants tankou dichlorodifluoromethane ammonia, reziste dilute asid ak silicone grease grès lubrifyan lwil oliv ak yon gwo ekspansyon mineral lwil ak low aniline points. Easy kristalize ak difisil nan low tanperati. Apwopriye varye anviwònman ke com nan kontakte ak atmosfè a, limyè solèy la, ozone, ak divès kalite sele lyen ke yo rezistan konbustion ak pwodwi chimik korozyon. Li pa rekòmande itilize nan pwodwi chimik tankou asid fò asid, nitrohydrocarbons, esters, chloroform, ketones. The general tanperati ranje !!7b{1}}}}% degre degre .
8, IIR butyl rubber sealing ring: It has excellent airtightness, heat resistance, sunlight resistance, ozone resistance, and good insulation performance; Has good resistance to polar solvents such as alcohols, ketones, esters, etc., and can be exposed to animal and vegetable oils or oxides. Suitable for chemical resistant or vacuum equipment. It is not recommended to use it together with petroleum solvents, kerosene, or aromatics. The general temperature range for use is -50~110 degree .
9, ACM acrylic rubber sealing ring: It has excellent resistance to oil, high temperature resistance, and weather resistance, but its mechanical strength, compression deformation rate, and water resistance are slightly poor. Generally used in automotive transmission systems and power steering systems. Not suitable for use in hot water, brake oil, and phosphate esters. The general temperature range for use is -25~170 degree .
10, NR natural rubber sealing ring: Rubber products have good wear resistance, elasticity, tensile strength, and elongation. But it is prone to aging in the air, becomes sticky when exposed to heat, expands and dissolves easily in mineral oil or gasoline, and is alkali resistant but not strong acid resistant. Suitable for use in liquids containing hydroxide ions such as automotive brake oil and ethanol. The general temperature range for use is -20~100 degree .
11, PU poliurethane kawotchou sele ring polyurethane kawotchou y bon, ak li mete rezistans press rezistans yo byen lwen siperyè kawotchou kawotchou rezistans aje rezistans, ozone rezistans% 2c ak lwil oliv rezistans yo tou bon, men yo fasil hydrolyzed tanperati. Jeneralman itilize nan -wo presyon ak mete-rezistan sele pwosesis, hydraulic silenn. jeneral tanperati ranje use 7b{3}}}}% degre degre .
