The TRP Reworker is a resource saving technology for the economical processing of rework materials based on the two-roll plasticizer (TRP) with integrated Roll Ex gear pump. In an automatic process, unvulcanized rubber compounds are processed particularly gently and continuously in order to return this rework material to the production process. In tire production, compound waste is unavoidable due to the process.

Read MoreEfforts to make rubber products more environmentally friendly (green) continue to increase. These efforts have become increasingly important to all rubber companies, large and small. Suppliers that produce rubber additives have increasingly focused efforts to provide products to the rubber industry that help meet the goal of increased sustainability. In this regard, Rhein Chemie (RCH), a business unit of Lanxess, currently has a sizeable portfolio of sustainable additives for rubber compounds, and also continues to explore the development of new products that meet the challenge of increased sustainability. This article will focus on currently available products and future products under development that will aid rubber companies in achieving the goal of more environmentally friendly products.

of modern cars, especially trucks with large storage space, are complex. Individual elements, such as the trunk floor, rear seat backs, rear covers, etc., have been produced for several years with dispersion based adhesive systems, with a growing trend of polyurethane reactive (PUR) systems.
Influence of functionalized terpolymer resin on carbon black reinforced rubber compounds and corelation with tire performance In recent years, the European Union (EU) has mandated reducing greenhouse gas emissions, especially carbon dioxide (CO2). Passenger cars are responsible for roughly 13% of the total CO2 emission in the E.U. From 2021, the CO2 emissions of new passenger cars must be reduced by 27% compared to 2015.
Read MoreGlobal distributor Wesco and Siemens have teamed up with a
local integrator to enable a major Tennessee tire manufacturer to
achieve consistent tension and save money. As Chad Garner, a
Nashville based application engineer with distributor Wesco,
related: “We were presented with a significant challenge by one
of our great customers: a tire manufacturer in the area. They
needed to upgrade their multiple wire drawing machines for tire
cord production in the plant.”
From mixing to extrusion, calendering, cutting and more, electric motors are critical at almost every step of rubber manufacturing. As motor technology has advanced rapidly over the past decade, latest generation high power density electric motors overcome many of the limitations of older models. They offer advantages in terms of size, precision and other critical areas;
Read MoreCarbon black is widely used throughout the rubber industry. Understanding the properties of carbon black dust and the specific
challenges these properties create for dust control is crucial for designing and implementing an effective dust collection system. A well designed dust collection system will ensure compliance with OSHA regulations and NFPA standards for carbon black dust safety.
Flash is excess rubber that protrudes from the surface of a molded part. This defect is common to injection, transfer and compression molding, and can be caused by worn tooling, improper venting, low clamping pressure, low viscosity or uneven flow. Even a small amount of mold flash reduces part quality; but excessive flashing can interfere with part performance or product assembly. Rubber molders have a choice of deflashing methods, but cryogenic deflashing provides cost saving advantages and improves quality and consistency across elastomers and applications.
