Standard Test Method for Oil Migration or Plasticizer Bleed-Out of Preformed Tape Sealants

Importancia y uso:

5.1 Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in a variety of sealing applications. In general, oil migration or plasticizer bleed-out is not desirable. However, in some limited instances, a controlled amount of plasticizer migration is sometimes desired in order to improve the penetration of the tape into the interstices of porous substrates. This test method is designed to indicate whether or not a preformed tape sealant exhibits oil or plasticizer migration and, if so, to what extent.
