CR Chloroprene Neoprene Rubber Sheet Roll Smooth Rough Embossed Neoprene
Roll Smooth Rough Embossed Neoprene
Chloroprene rubber SN242 is high bond strength, it is obtained by mercaptan modified and Chloroprene monomer by emulsion polymerization with high rate of crystallization, for using a Nairit recipe and process technology. It can be seen as an equivalent to DENKA A-90 of the Japan.
Properties and Characteristics Chloroprene rubber SN242,which has a fast rate of crystallization and stronger cohesion, has the highest viscosity among the SN242-series, compared with CR242, has better solubility and uniformity, preparing adhesive cements by SN242 in light in color and storage stability. It has excellent bonding strength, quick grips, easy handing, the adhesion layer to keep a long time, can be dissolved in toluene or mixed solvents. It exhibits resistant to ozone, weather, oil, chemical corrosion and extension of the fine is not flammable. It has the same applied properties as DENKA A-90 of the Japan.
1.Appearance: white or light yellow chips, with talcum as a release agent, no mechanical impurities. 2. Typical Polymer Properties
Brookfield solution viscosity(map.s,5% toluene solution at 25℃) 34-40 Mass fraction of volatiles (wt.%0 ≤1.3 Mass fraction of ash(wt.%) ≤1.0
It is a basic raw material of preparing adhesive cements, can be used alone or combination with other types, preparing adhesive where a very higher tack is required. Adhesive is suitable for bonding of the shoe industry, rubber leather, wood, metal and construction materials
