Product Introduction
EPDM Flexible Bellows, also known as EPR Flexible Bellows and ethylene propylene flexible Bellows, are designed as a cover or expansion bellows to take over axial, lateral and angular movements in pipeline systems and protect components against alkalis, strong alkaline, detergent, hot water, steam, ozone, etc.
EPDM Rubber Flexible Bellows and dust boots have wide sealing applications due to these excellent chemical resistance properties and its superior ozone resistance.
EPDM Flexible Bellows are usually produced by silicone rubber compression molding, extrusion moulding or rubber injection moulding.

EPDM Flexible Bellows Advantages:
1. Anti-ozone and w eather resistance
2. Aging & Corrosi on re sistance
3. Waterproof and steam resistance: bathroom equipment, auto radiator && brake system.
4. Electrical insulation: wire & cable
5. Good heat resistance (dry heat): Working Temperature range -50oC-150oC. ( -60oF-300oF )
6. Low density and high filling property: can be made into low-cost rubber compounds bue to absorption of lots of oils and fillings.
EPDM Flexible Bellows Disadvantages:
1. Slow curing rate
2. Poor self-adhension and mutual viscosity
3. Poor processability: difficult to blend with other unsaturated rubbers
4. Not recommanded for petroleum oils, mineral oil, die-ester lubricants or fuel exposure
Rubber Introduction:
Copolymer of NBR with butadiene and acrylate.It is characterized by excellent resistance to gasoline and aliphatic oils and is superior to other general rubber.Good heat resistance, air tightness, wear resistance and water resistance are good, strong adhesion.Disadvantage is cold resistance and ozone resistance, strength and low elasticity, poor acid resistance, poor electrical insulation, polar solvent resistance performance is also poor.Service temperature range: about -30℃~+100℃.Mainly used in the manufacture of various oil-resistant products, such as rubber hose, sealing products, etc.
Ethylene-propylene rubber (EPMEPDM) copolymer of ethylene and propylene, generally divided into binary ethylene-propylene rubber and EPDM.It is characterized by excellent resistance to ozone, ULTRAVIOLET, weather and aging, ranking first in general rubber.Good electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, low specific gravity, high filling fit.Heat resistance up to 150℃, polar solvent - ketone, ester, but not resistant to aliphatic hydrocarbon and aromatic hydrocarbon, other mechanical properties slightly inferior to natural rubber.The disadvantage is that self - viscosity and mutual viscosity is very poor, not easy adhesion.Operating temperature range: about -50℃~+150℃.It is mainly used for lining of chemical equipment, covering of wire and cable, steam hose, heat-resistant transport belt, rubber products for automobile and other industrial products.
Silicone rubber (Q) is a special rubber containing silicon and oxygen atoms in the main chain, among which silicon element plays the main role.Its main characteristics are high temperature resistance (the highest 300℃) and low temperature resistance (the lowest -100℃), is the best cold and high temperature resistance rubber at present;At the same time, excellent electrical insulation, high stability to thermal oxidation and ozone, chemical inertness.Disadvantages are lower mechanical strength, oil resistance, solvent resistance and poor acid and alkaline resistance, more difficult to vulcanize.Service temperature: -60℃~+200℃.It is mainly used in the production of high and low temperature resistant products (rubber hose, sealing parts, etc.), high temperature resistant wire and cable insulation layer, because of its non-toxic and tasteless, also used in food and medical industry.
Fluororubber (FPM) is an organic elastomer composed of fluorinated monomers.Have multiple types, import of domestic variety complete, can meet the demands of all kinds of customers, and fluorine rubber excellent chemical stability, resistance to high temperature is 300 ℃, can say is one of the best in elastomer, fluorine rubber aging resistance performance is good, especially after 10 years in the natural storage of dupont developed VitonA can still unsatisfactory, the mechanical performance of the fluorine rubber was also surprisingly good, general fluorine rubber strength between 15.0 ~ 25 mpa, elongation was 200% ~ 600%, the tear strength between 2 ~ 7 mpa, import or match the performance of the more significant by our factory,Fluororubber has good electrical properties and low air permeability. Fluororubber is characterized by high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and resistance to a variety of chemicals. It is mainly used in the national defense industry to manufacture vacuum, high temperature and chemical corrosion resistant sealing materials, rubber pipes or other parts for aircraft and rockets, as well as automobile industry.
Polyurethane rubber (AU/EU) is an elastomer of polyesters (or polyethers) polymerized with diisocyanate compounds.Its characteristic is good wear resistance, in all kinds of rubber is the best;High strength, good elasticity, good oil resistance.Ozone resistance, aging resistance, air tightness and other excellent.The disadvantages are poor temperature resistance, poor water resistance and alkali resistance, poor resistance to aromatic hydrocarbons, chlorinated hydrocarbons and ketones, esters, alcohols and other solvents.Service temperature range: about -30℃~+80℃.Make tires from parts, gaskets, shockproof products, and wear, high strength and oil resistance.
