A product acrylonitrile butadiene rubber, silicone tube, probably share at about 3.2 to 3.5, hardness 60-80 and sample the many times, or proportion
Reached, the product to do out the appearance is very difficult to see (mainly out of the mold is easy to scratch), or the proportion did not meet, there is sulfur
If the system less, the product easy to unfamiliar.
Shenzhen odd margin silicone rubber share: zinc oxide to do the proportion of the proportion of the filler is certainly not up to a very far.
Requirements? Only the fine iron powder as filler. (not allowed to join metal powder, adding iron to the naked eye can see
Out) the proportion of 3 points is a great difficulty, I have done 70 degrees NR and 90 degrees is also a product of the proportion of customers, I
Joined the magnetic powder to reach his product weight, I calculated the proportion of 2.8, to make the product is good, at this time the use of ZNO formula
The use of the coupling agent plays a key role. ZNO to be used with high zinc content, high activity. The use of coupling agent can improve the filling and
The combination of the two phase interface of rubber, the role of the coupling agent is not only in the white smoke, and inorganic filler in the role, this time also has a certain
For.
