    Abstract: The present invention relates to curable barrier encapsulants or sealants for electronic devices that have pressure sensitive adhesive properties. The encapsulants are especially suitable for organic electronic devices that require lower laminating temperature profiles. The encapsulant protects active organic/polymeric components within an organic electronic device from environmental elements, such as moisture and oxygen.

  • Publication number: 20150011696
    Abstract: A method can include consecutively batch processing at least two different polyethylene grades in pellet form in a pellet handling unit. A ratio of a melt flow index (MI) of a first polyethylene in pellet form (MIf) to a MI of a later processed polyethylene in pellet form (MIl) can be smaller than 0.30. The method can include processing an intermediate polyethylene grade in pellet form. An amount of intermediate polyethylene grade processed can be at most 1/100th of a handling capacity of the pellet handling unit. The intermediate polyethylene grade can have the same MI as the later processed polyethylene in pellet form.
