Top Quality EVA Valve Bags 25kg - Low Melt Valve Bags for Rubber Additives – Zonpak

Product Detail

Rubber additives in form of powder or granule include carbon black, white carbon black, zinc oxide, and calcium carbonate are usually packed in kraft paper bags. The paper bags are easy to break during transportation and difficult to dispose after used. To solve these problems, we have specially developed low melt valve bags for rubber additives manufacturers. These bags together with the materials contained can be direct put into an internal mixer because they can easily melt and fully disperse into the rubber compounds as a minor effective ingredient. Different melting points (65-110 deg. C) are available for different application conditions. BENEFITS:
