How can rubber products be softened?
Softener generally need to add a certain amount of plasticizer in rubber processing. It is usually of low softness to make the rubber softMolecular substances, they can increase the plasticity of rubber, liquidity, adhesion, in order to facilitate molding and molding and other process operations. It can also help the powder mixture to disperse and reduce the mixing temperature, at the same time, it can reduce the viscous flow temperature and the glass transition temperature of rubber, and improve the low temperature resistance of rubber.
Rubber softener for fluid or semi fluid, dangerous goods, should be stored in the rain (the most important) ventilation dry place shading.A package (drums, plastic barrels, plastic bags), according to the needs of the customer.
Rubber softener is a softening agent, which requires its own energy and rubber has a good affinity, in the improvement of rubber processing, can reduce the mixing power consumption, promote the uniform dispersion of a variety of accessories, craft to improve the performance of vulcanized rubber elongation elasticity etc.. In a word, softening, plasticization, adhesion, strengthening and anti-aging are the main mechanisms.
Softener most used in rubber processing oil department softener (this kind of softener is actually physical plasticizer). The oil softener is processed products in petroleum refining process, has good softening effect, rich source, low cost features. This kind of softener including aromatic oil, paraffin oil, naphthenic oil, heavy oil, paraffin, Vaseline, asphalt, petroleum resin and so on. Rubber softener (oil) is a refinery in the oil processing products, it is liquid products with different viscosity, the difference is that contain different hydrocarbon components. The rubber softener (oil) according to the composition of the hydrocarbons can be divided into paraffin base oil, naphthenic oil (naphthenic oil) and aromatic oil (aromatic oil).
