Characteristics: Bright colour, strong colouring power, high purity, resistant to strong sunlight, resistant to atmospheric influences, resistant to dirty gases and various climate changes. Good alkali resistance, poor acid resistance. Rubber products coating adhesion is quite large, in sunlight, air, acid and alkali in the heat of sulphuric acid that is reactive, in the case of sulphur or hydrogen sulphide does not change. Stability requirements for moulding and processing are not strict on the processing temperature requirements. Used in brake pads, brake panels and other asbestos plastic products can improve the coefficient of friction and reduce friction loss. Economical to use.
The use of iron oxide pigment in rubber: Generally, the raw rubber is cleaned and refined, and then mechanically processed to get the necessary plasticity, and then added with vulcanising agent and fillers such as iron oxide pigment, zinc oxide and calcium carbonate for blending to get the raw rubber. Then it is processed and moulded into various rubber parts.
In the application of rubber and plastics, iron oxide red, which does not contain heavy metal ions such as copper and manganese, can be used in aviation tyres to prevent the aging of rubber. Iron oxide pigment has strong colouring power and pure colour, it is used as colouring agent and filler in PVC plastic flooring and PVC colouring film, and it can be used in thermosetting plastics such as Bakelite powder, Bakelite powder and polyolefin. In thermoplastic plastics: the use of iron oxide pigment in masterbatch or slurry preparation will be more popular in the industry.
