1. Blending Rubber
Each tire can contain up to 10 different rubber blends.
The blend determines the subsequent characteristics of various tire components. In addition to rubber and fillers, numerous chemical additives are heated and combined with one another as activators and blending aids etc.
Technical Requirements of the Belts
The belts must be exceptionally robust and resistant to incisions, have good release properties and be able to withstand the chemical additives. In some blending processes, water has to be conducted away via the belt.
Directly after the blending process, the finished blend has to be conveyed at a product temperature of up to 175 °C.
Forbo Movement Systems supplies both fabric-based belts (Siegling Transtex, Siegling Transilon) and plastic modular belts (Siegling Prolink) for individual sections of the compounding facility. This portfolio offers optimum belts for any compounding facility.
Different surface patterns on the belts decrease the contact area
to the blend and improve the release properties of the hot and sticky rubber. Resilient coatings and robust fabric designs ensure long services lives and smooth operations. Our PVK150 MF BXB-NA black FR (Siegling Transtex) is used after the kneader and is 100% silicone free.
The fabric-based types (Siegling Transtex, Siegling Transilon) are easy to splice with mechanical wire-hook or clamp fasteners.
