GETREN® - sliding and release agents for the rubber industry
Mechanical rubber goods are used worldwide in a large number of applications. They are distinguished by high durability, flexibility and moldability. For an optimal exploitation of the rubber properties, process auxiliaries that facilitate the production and processing of the rubber goods are required.
Evonik offers a wide range of such additives, varying from sliding polymers for window profiles to release agents for different kinds of rubber hoses or molded rubber parts. Thanks to our many years of experience, global presence and innovative strength, we can provide a high level of support to our customers and help you in optimizing your production processes.
Mold release agents of the GETREN® M series from Evonik can be used for all compression and injection molded rubber parts, drive belts, and conveyor belts. They allow easy demolding of rubber parts, reduce soiling of the mold surface and ensure the dimensional accuracy of the molded rubber part.
For mold release we offer both silicone oil based and silicone oil free formulations that can be used for all the usual types of polymers in compression and injection processes.
GETREN® B 7100 - Antiblocking agent to be used on green tubes before vulcanization, preventing undesired adhesion and suitable for all conventional types of rubber.
GETREN® D 1570 - Anionic cleaning concentrate for hoses in order to wash off any residues from the production process, suitable for all conventional types of rubber.
GETREN® L release agents for long hose production are used in the continuous extrusion of rubber on mandrels, with hose lengths between 2 and 400 m.
Products of the GETREN® R series reliably reduce static as well as sliding friction in the production of shaped hoses. They ensure a smooth release from the mandrel without time constraints or damage to the hoses. Our GETREN® R release agents are extremely resistant to the high temperatures and pressure during vulcanization.
Evonik's product portfolio offers, in addition to release agents for standard polymers like EPDM (ethylene/propylene terpolymers) and NR/NBR (natural rubber/nitrile rubber), products for special applications such as ECO (epichlorohydrin copolymers) and acrylic rubber mixtures.
The products of our GETREN® P series are water-based silicone oil emulsions as well as OMS based sliding polymers that form a solid lubricating film on the rubber seal. They provide excellent sliding properties, allowing an easy assembling of seals and window frames requiring only little effort.Product listing
