N220 |
s suitable to each kind
of rubber, the resistance to wear is
higherthan N330 10%-20%, can entrust
with the colloidal particle rubber
highlongitudinal strength and the anti-
peel strength, and has the
certainelectrical conductivity. Mainly
uses in the carrying capacity
embryo,while with embryo's tread rubber,
and high strength needs, the highwear-resisting
rubber product. |
| N330 |
Is one kind makes up the
strong performance good carbon black,
canentrust with the colloidal particle
to be better strongly extends
theperformance, anti- rends the
performance, the resistance to wear
andthe elasticity. Mainly uses in the
tire, the curtain clothrubber, and each
kind of rubber industry product. |
| N326 |
Has the higher
longitudinal strength, the anti- peel
strength, theresistance to wear in the
natural rubber and anti- jumps the
crackperformance. Mainly uses in to
request the intensity to be high,
theheat generation low tire (including
cross country embryo) the treadrubber,
also is suitable for the conveyor belt,
the seal product andother high grade
rubber industry products. |
| N660 |
This is suitable for
each kind of rubber, with partly makes
up thestrong carbon black to compare,
has a higher structure, the
granulethinner, is easy in the sizing
material to disperse, the curing
rubberlongitudinal strength, the anti-
peel strength and surely extend
thestress high, but distorts slightly,
heat generation low, theelasticity and
bears bends harasses the performance to
be good. Mainlyuses in the tire curtain
adhesive plaster, the tire tube, the
bicycle,the rubber tube, the adhesive
tape, the electric cable, the shoesclass
and the rolling product, the model
product and so on. |
