哈氏合金外殼,PTFE隔膜,美國(guó)Versa-matic威馬E4系列1.25寸氣動(dòng)隔膜泵E4HA5F5H0

Conductive Acetal: Tough, impact resistant, ductile. Good abrasion resistance and low friction surface. Generally inert, with good chemical resistance except for strong acids and oxidizing
|agents.
EPDM: Shows very good water and chemical resistance. Has poor resistance to oils and solvents, but is fair in ketones and alcohols.
FKM:(Fluorocarbon) Shows good resistance to a wide range of oils and sovents; especially all aliphatic, aromatic andhalogenated hydrocarbons, acids, animal and vegetable oils.
Hot water or hot aqueous solutions(over 70F) will attack FKM.
Hytrel@: Good on acids, bases, amines and glycols at room temperatures only.
Neoprene: All purpose. Resistance to vegetable oils. Generally not affected by moderate chemicals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids, ketones, esters and nitro hydrocarbons and chlorinated aromatic hydrocarbons.
Nitrile: General purpose, oil-resistant. Shows good solvent, ol, water and hydraulic fluid resistance. Should not be used withhighly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
Nylon:6/6 High strength and toughness over a wide temperature range. Moderate to good resistance to fuels, oils and chemicals.
Polypropylene:A thermoplastic polymer. Moderate tensile and flex strength. Resists stong acids and alkali. Attacked by chlorine, fuming nitric acid and other strong oxidizing agents.
PVDF:(Polyvinylidene Fluoride)A durable fluoroplastic with excellent chemical resistance. Excellent for UV applications.
High tensile strength and impact resistance.
Santoprene8: Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life. Excellent abrasion resistance.
UHMW PE:A thermoplastic that is highly resistant to a broadrange of chemicals. Exhibits outstanding abrasion and impact resistance, along with environmental stress-cracking resistance.
Urethane: Shows good resistance to abrasives. Has poor resistance to most solvents and oils.
Virgin PTFE:(PFA/TFE) Chemically inert, vitually impervious.
Very few chemicals are known to chemically react with PTFE; molten alkali metals, turbulent liquid or gaseous fluorine anda few fluoro-chemicals such as chlorine trifluoride or oxygen difluoride which readily liberate free fluorine at elevated temperatures.
