It delivers critical performance in tires, other rubber products and specialty chemicals as well. Crystex Insoluble Sulphur is appreciated for its features such as superior dispersion and enhanced flow. This has gained us high rising demands in the market. It is highly resistant to reversion of sulphur at high temperatures as tested by our quality controllers.
