OEM China 50 Micron EVA Bags - Rubber Compounding Bags – Zonpak

Rubber compounding refers to the addition of certain chemicals to raw rubber in order to obtain the desired properties. ZonpakTM rubber compounding bags are specially designed bags for packing rubber ingredients and chemicals used in the rubber compounding process. The materials e.g. black carbon, anti-aging agent, accelerator, curing agent and aromatic hydrocarbon oil can be preweighed and temporarily stored in the EVA 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 a mixer, and the bags will melt and fully disperse into the rubber as a minor effective ingredient. These bags largely help rubber compounding work by providing exact adding of chemicals, cleaner work environment and higher practice efficiency. Bags with different melting point (from 65 to 110 degree Celsius) are available for different rubber mixing conditions. Size and color can be customized according to the customer’s specific application requirement.
