Rubber compounding bags (low melt bags) are specially designed batch inclusion bags to pack rubber ingredients and chemicals used in the rubber compounding process. The materials e.g. black carbon, anti-aging agent, accelerator, sulphur and aromatic hydrocarbon oil can be preweighed and temporarily stored in these bags. As the material of the bags has good compatibility with natural and synthetic rubber, these bags together with the materials packed can be direct put into an internal mixer, and the bags will melt and fully disperse in the rubber as an effective ingredient.

These bags largely help rubber compounding work by providing exact dosing of chemicals, cleaner work environment and higher practice efficiency. Bags with different melting point (from 70 to 115 degree Celsius) are available for different rubber mixing conditions. Size and color can be custom made according to the customer’s specific application requirement.
