Safety & Health

Health and Safety Information
  • Appropriate literature has been assembled which provides information concerning the health and safety precautions that must be observed when handling the LANXESS products mentioned in this publication.
  • For materials mentioned which are not LANXESS products, appropriate industrial hygiene and other safety precautions recommended by their manufacturers should be followed.
  • Before working with any of these products, you must read and become familiar with the available information on their hazards, proper use, and handling.
  • This cannot be overemphasized.

Storage & Handling

Storage and Handling information
  • At LANXESS production facility, the K-Flex® 500 plasticizers are stored in type 304 stainless steel storage tanks.
  • These storage tanks are nitrogen padded to reduce discoloration of the product.
  • Type 304 stainless steel pipe and valves are also used.
  • High density polyethylene has been shown to be suitable for product shipment but we have no direct experience in piping systems.
  • Since K-FLEX products are excellent plasticizers for polyvinyl chloride (PVC), PVC piping systems should not be used.
  • Sliding vane type positive displacement pumps have given us excellent service.
  • It is recommended that storage tanks be heated and insulated and that pumps and transfer piping also be heat-treated and insulated.
  • Our engineers are always ready to discuss the storage and handling of any of our products.
