  • Patent number: 11091610
    Abstract: A method and composition of making polymer products from thermoplastic polymers by melt processing. Cross-linked polyethylene are mixed with at least one thermoplastic matrix polymer to form a polymer composition which is melt-processed. The cross-linked polyethylene is formed by a finely divided powder with particles having a screened size of less than 600 ?m and a D50 of 200 to 400 ?m. Cross-linked polyolefin can be used in a cost-effective and simple manner so that products generally considered a waste, such as scrapped cross-linked polyethylene pipes or unused cross-linked polyethylene discarded in e.g. pipe making processes, can be recycled and used as a starting material for polymer products.

Utilizing the material as an alternative to DTHFP in rubber production avoids subsequent leaching of the DTHFP into the environment as the oligomeric 2, 2-difurylpropane (DTHFP) gives rise to much lower levels of leaching.

  • Patent number: 10336962
    Abstract: This invention provides a threaded connection for pipe or tube that has a non-sticky surface and that suppresses the occurrence of rust and exhibits excellent galling resistance and airtightness even in an extremely low temperature environment without using compound grease, a method of producing the same, and a composition for forming a solid lubricating coating on the threaded connection. A solid lubricating coating (24) formed from a composition containing a binder, a fluorine addition agent, a solid lubricant and a rust proof addition agent is coated as a topmost surface treatment coating on a contact surface of at least one of a pin and a box. Even when exposed to an extremely low temperature environment, the solid lubricating coating (24) can maintain adhesiveness and exhibit a lubricating function, can suppress the occurrence of galling of a threaded connection, and can also secure airtightness after fastening.
