Drag, pressure, and leakage are important factors that affect the quality of the extruded rubber product in the rubber extrusion process. Drag: Drag refers to the frictional force that occurs between the rubber material and the surface of the extrusion die or head. The drag force opposes the movement of the rubber material and is … Continued
Line takeoff speed in rubber extrusion refers to the speed at which the extruded rubber product is pulled or drawn away from the extrusion die or head. This speed is also known as line speed or haul-off speed. The line takeoff speed is a critical parameter in rubber extrusion as it affects the quality of … Continued
Rubber compounds exhibit unique flow behavior during extrusion due to their viscoelastic properties. When a rubber compound is subjected to shear stress during extrusion, it experiences both viscous and elastic deformation. Initially, the rubber compound behaves as a solid and resists deformation due to its elastic properties. As the shear stress increases, the compound starts … Continued
Goodyear Rubber knows the value of EPDM (ethylene propylene diene terpolymer) as a durable synthetic rubber used in a variety of application needed strong heat resistance and excellent weathering properties. That’s one reason it is used for roofing. Its two primary ingredients, ethylene and propylene, come from oil and natural gas. Factors that impact economics … Continued
On its own, unprocessed rubber is pretty useless. It gets brittle when cold, does not smell so good and is too sticky for useful application. That’s why tapped rubber from the Hevea brasiliensis tree combines with the dripping latex of many trees to get filtered, washed and reacted with acid to make the rubber stick … Continued
Goodyear Rubber Company of Southern California has been manufacturing urethane products for more than 30 years. Urethane products can assume properties of materials like metal, plastic and even conventional rubber but without the density and rigidness. The material is often used to make roller castings. Urethane and Rubber Urethane boasts exceptional abrasion, cut and tear … Continued
About least 279 million tires are discarded and recycled annually keeping significant amounts of rubber out of landfills. Recycled rubber is friendly to the environment. The Benefits of Recycling Less energy is needed in using recycled rubber rather than producing new rubber. It also decreases the demand for new natural rubber by helping keep rubber … Continued
What is a rubber extrusion and how does it differ from rubber molding? The big difference is that uncured rubber is pushed through a die into an extruder. An extruder is a machine (that costs around $100,000) that applies shear forces to a raw ingredient (like rubber) to make it into a final product. The … Continued

This indicates that the reinforcing potential of carbon black is closely related to the amount of highly energetic sites that can be well quantified by the applied … Continued
Hi. Flynn Sears here checking in on a Technical Rubber Extrusion Process piece: Tackling Extrusion Die Swell . The Extrusion process is still largely a form of art on the part of the operator. There is no cavity to form the rubber part in the curing process. Rather, the extrudate must go through the vulcanization … Continued
