Material characteristics of naphthenic oil (special softener for rubber):

Naphthenic oil (special rubber softener) has low volatile and high flash point

The naphthenic oil series with high flash point and low volatile provides better weather resistance and low volatile at high temperature for the processing of rubber products. The paraffin-based oil has excellent performance in the fields of automobile rubber parts, wire and cable outer protective insulating sleeve, household appliance parts, and new building materials sealing.

Low aromatic content of naphthenic oil (special rubber softener)

The characteristic aromatics content of naphthenic oil is low, which is particularly important in the application of peroxide vulcanization process. Low aromatics content can reduce the consumption of vulcanizing agent, thus reducing the cost. The low aromatic hydrocarbon content and low volatility of paraffin-based oil are far better than other rubber softeners with insufficient refining.

The combination of low aromatic hydrocarbon content and low volatility of naphthenic oil plays an important role in the application of EPDM rubber automotive door and window sealing strips, gaskets and automotive flexible rubber tubes. The low aromatic hydrocarbon content improves the anti-oxidation and degradation performance of rubber, and the low volatility helps to prevent aging and shrinkage, and is conducive to improving the bad appearance of products (such as roughness and bubbles). These two characteristics are conducive to extending the service life of rubber products.

Naphthenic oil (special softener for rubber) is widely used in IIR (butyl rubber), EPM (ethylene propylene rubber), EPDM (ethylene propylene diene rubber), IR (polyisoprene rubber), NR (natural rubber) and some thermoplastic rubbers, especially in rubber products requiring small odor, good initial color, good heat resistance and light resistance, which is extremely important in the manufacture of household appliances, children's toys and other products. In many reference materials of synthetic rubber industrial application, naphthenic oil has been widely used in rubber processing formula and played a very important role.
