EPDM seal / anti-aging EPDM rubber strip:
Features: wide temperature range (-40 ℃ ~ + 120 ℃), water, fire, insects, wind, every light, crash
Applications: ethylene propylene diene monomer (EPDM) rubber foam composite made with dense, containing a unique tongue-shaped metal fixture and buckle, durable, plays a key role in a variety of electrical appliances.
Raw materials are mainly imported EPDM rubber (EPDM), sealing, water, fire, insects, wind, every light, crash and long working life. Particular product is compressed by having good flexibility and resistance to deformation, anti-aging , ozone, chemical action, a wide temperature range (-40 ℃ ~ + 120 ℃) of ethylene propylene diene monomer (EPDM) rubber foam composite made with dense, containing a unique metal fixture and tongue-shaped buckle, sturdy durable. plays a key role in a variety of electrical appliances.
1, using microwave curing process forming a smooth surface appearance without seams.
2, has a good elasticity and resistance to compression set resistance, excellent anti-aging properties.
3, excellent flame retardant, low smoke, low toxicity.
4, product extrusion stability, high dimensional accuracy.
5, non-toxic, environmental protection, anti-aging, high temperature, stable performance, summer, winter can maintain good performance.
EPDM rubber (EPDM) material properties:
A, ozone resistance, and excellent oxidation resistance
EPDM in the molecular structure of the main chain does not contain a double bond, can be completely resistant to the attack of ozone in the air. Ozone concentration 100PPHM environment, cracking does not occur 2,430 hours (500 hours cracks butyl rubber, chloroprene rubber, cracking 40 hours); in 50PPHM, 30% of the static pull condition 150 hours no cracks (butyl rubber 2 hours cracking).
B, excellent weather resistance
EPDM long-term use in the sun, damp, chilly natural environment.
C, excellent heat resistance
EPDM long-term use under conditions of 120 ℃, the maximum temperature 150 ℃.
D, excellent low temperature properties
Poly methylene main chain flex provide good low temperature properties, having a glass transition temperature between -35 ℃ --65 ℃, curing products, or the majority, i.e. with a more flexible at low temperatures under conditions of -25 ℃ good flexibility and low compression set, so that it will not lower the ambient temperature is too low and the sealing performance in the cold regions, so that the construction is easier in cold regions.
E, chemical resistance
EPDM resistant to many polar solutes, such as brake oil, acids, alkalis, alcohol, etc.; resistant non-polar solute poor performance, such as gasoline and other hydrocarbon solvents, etc., can be obtained through the use of ultra-high molecular medium oil under the oil filled case sex.
F, EPDM synthetic rubber in almost all of the lightest kind of gravity (also below plasticized polyvinyl chloride), so the finished product will have a lighter weight per meter. This also determines that they have a wide range of applications.
