PERFORMANCE

NR:
NR rubber expansion joints are characterized by high elasticity, high elongation, excellent tear resistance and electrical insulation, good wear resistance and drought resistance, good processability, easy adhesion to other materials, and superior to most synthetic rubber in comprehensive performance.

The disadvantages are poor oxygen and ozone resistance, easy aging and deterioration, poor oil and solvent resistance, low acid and alkali corrosion resistance and low heat resistance.

Use temperature range: about – 60 +80.

EPDM:
EEPDM rubber joint is also called EPDM rubber expansion joint. It is characterized by excellent ozone resistance, ultraviolet resistance, weather resistance and aging resistance, ranking first in general rubber. Electrical insulation, chemical resistance, impact elasticity is good, acid and alkali resistance, small proportion, can be filled with high coordination, heat resistance can reach 150 C, polar solvent-ketone, ester, but not resistant to aliphatic hydrocarbons and aromatic hydrocarbons, other physical and mechanical properties slightly inferior to natural rubber and superior to styrene-butadiene rubber.

The disadvantage is that self-adhesive and mutual-adhesive are very poor, and it is not easy to bond.

Use temperature range: about – 50 +150.

NBR:
NBR rubber joint is also called NBR rubber connector. It is characterized by excellent gasoline and aliphatic hydrocarbon oil resistance, second only to fluorine rubber, and superior to other general rubber. Good heat resistance, air tightness, wear resistance and water resistance, strong bonding force.

The disadvantages are poor cold and ozone resistance, low strength and elasticity, poor acid resistance, poor electrical insulation and poor polar solvent resistance.

Use temperature range: about – 30 +100.

CR:
EChloroprene rubber (CR) joints have excellent anti-oxygen, anti-ozone, non-flammability, self-extinguishing after ignition, oil resistance, solvent resistance, acid and alkali resistance, aging resistance, good air tightness and other advantages; their physical and mechanical properties are also better than natural rubber, so they can be used as general rubber and special rubber.

The main shortcomings are poor cold resistance, large proportion, high relative cost, poor electrical insulation, easy to stick and roll, easy to scorch and easy to stick mold in processing. In addition, raw rubber has poor stability and is not easy to preserve.

Use temperature range: about – 45 +100.
