Rubber Microcrystalline Protective Wax (Ozone Protective Wax) is a rubber Ozone protector / antioxidant of wax compound mixture, selected from a variety of paraffin wax, microcrystalline wax, etc.. It forms a supersaturated solution of paraffin wax system in rubber products during application and storage, and makes continuous paraffin hydrocarbon molecules migrate to the rubber surface. This migration is on-going until the paraffin concentration achieving a balance effect finally on the surface and internal rubber products. On basis of wax solubility and migration, the dynamic balance keeps a complete protective film on the rubber surface with long-term stability, thereby preventing oxygen and ozone attack and protecting from destruction of the rubber. The protective film shows an excellent stability against dynamic stress, which, in the meantime also takes a role of weakening light damage to rubber.
Granular Wax suitable for use with automatic and manual measurement, in order to ensure dispersion, it is recommended to join in the initial mixing. In the rubber mixing and curing process the product was completely dissolved. It shows good migration performance and excellent protection effect at general environment.
This product is recommended to use in the internal mixer. If the application in the open mill, it is recommended the mixing temperature should exceed the melting point above 10 ℃.
Tire formula recommended dosage 1-4phr, conveyor belts with 2-6phr, in other rubber products based on experimental results to determine. The recommended maximum dosage is 10phr.
Tires, conveyor belts, etc., all kinds of rubber products for high temperature applications. It can be used with chemical antioxidant to extend the scope of protection and to improve the protective effect.
