ELASTOSIL®R401
HCR silicone
Characteristics
Vulcanizates made from these compounds exhibit an unique combination of characteristics. They are noted for their good flexibility , high transparency ,and mechanical properties. The compounds are easily pigmented with ELASTOSIL®PT Pigment Pastes and have good processing characteristics. The various grades can be mixed with each other in any proportion to achieve intermediate hardnesses.
Application
ELASTOSIL®R401/20 TO R401/90 have many different uses being suitable for molded articles and extrusions such as seals , sheet, tubing, and profiles. ELASTOSIL®R401/20 is a special formulation for the production of flexible extruded articles,with the aid of Curing Agent E. This grade is not suitable for press vulcanization with Curing Agents C1 and C6 Postcured articles can be used for food and drug application.
Storage
ELASTOSIL®R401 should be stored at 25℃ in the originally sealed container . The best for use before end date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily men that the product no longer usable .In this case, however , the properties required for the intended use must be checked for quality assurance reasons .
Safety information
Detailed safety information is contained in each material data safety sheet , which can be obtained from our sales offices.
