Abstract
A plastic bearing material of a bearing may include a block copolymer. The block copolymer may include structural blocks of two or more different polymers. A first polymer may include at least one of polyamide-imide and polybenzimidazole. A second polymer may include at least one of polydimethylsiloxane, methyl vinyl ether and polyisobutene. A method for manufacturing a plastic bearing material may include synthesizing a structural block of a first polymer and a structural block of a second polymer to define a block copolymer via a condensation reaction.
Claims21
A plastics bearing material comprising a block copolymer.
A bearing comprising:
- a plastics bearing material including a block copolymer, the block copolymer including a first structural block of a first polymer and a second structural block of a second polymer;
- wherein the first polymer includes at least one of polyamide-imide and polybenzimidazole, and the second polymer includes a polymer having a lower hardness than the first polymer.
A method for manufacturing a plastics bearing material, comprising:
- providing a first structural block of a first polymer, the first polymer including at least one of polyamide-imide and polybenzimidazole;
- providing a second structural block of a second polymer, the second polymer including a polymer having a lower hardness than the first polymer;
- and
- synthesising the first structural block with the second structural block to define a block copolymer via a condensation reaction.
