  • aqueous
  • These molecules, which are chemically grafted to the PTFE surface, allow the particles to disperse easily in both aqueous and solvent media without the need for added surfactants or stabilizers that can interfere with desired properties. (polysciences.com)
  • resin
  • Porosity of the inner and outer surfaces is varied by changing, in the respective billets, the lubrication level and/or the PTFE resin characteristic average particle size. (google.es)
  • 5. The dual porosity tube of claim 1, wherein the average particle size of the PTFE resin of the first billet and the average particle size of the PTFE resin of the second billet are different. (google.es)
  • 6. The dual porosity tube of claim 5, wherein the average particle size of the PTFE resin in the first billet is less than or equal to about 200 μ. (google.es)
  • composite
  • The immersion deposited ZnO-PTFE composite coating on modification with either stearic acid or fluoroalkylsilane resulted in a better superhydrophobic surface. (hindawi.com)
  • Gaskets
  • PTFE envelop gasketis a non-metallic gaskets ,general consists of two parts of the coating and inserts.The coating of PTFE envelop gasketmainly plays the role of corrosion,usually made of PTFE .The inserts (fil. (burrillandco.com)
  • adhesive
  • Alternatively, a plurality of discrete pieces of porous PTFE may be adhered together by an adhesive. (google.com)
  • The presence of the adhesive provides a significant increase in stiffness and hence in carvability beyond that possible in a single layer of porous PTFE without the adhesive. (google.com)
  • tube
  • 4. The dual porosity tube of claim 1, wherein the dual porosity tube has a microstructure having internodal distances at inner and outer surfaces of the dual porosity PTFE tube within a range of about 0.10-200 μ. (google.es)
  • 8. The dual porosity PTFE tube as in claim 1, wherein the first tubular billet is an inner billet and the second tubular billet is an outer billet. (google.es)
  • materials
  • PTFE is resistant to all chemical products and solvents with the exception of alkaline materials. (alibaba.com)
