Eastman architectural glazing products include Saflex polyvinyl butyral (PVB) interlayers for glass lamination as well as Vanceva® Colors PVB interlayers.Architects &l engineers are taking advantage of our products which include structural performance, a variety of colors, acoustic sound reduction, and solar UV protection that provide the added benefits of safety, security, and weight reduction inherent to the PVB when laminated between two pieces of glass.

SAFLEX PVB PRODUCTSHere we introduce the main products most widely used in architectural laminated glass,including SAFLEX CLEAR,SAFLEX SOUND ACOUSTIC,SAFLEX DG STRUCTUREAL ,SAFLEX VANCEVA PVB INTERLAYER.

  1. Saflex DG41 Structural interlayer

Different from normal clear PVB interlayer,DG41 is structural PVB interlayer that offer high impact resistance and high structural performance.


  1. Post breakage safety: Higher load capability sustains safety after breakage.
  2. Superior edge stability :Enhances delamination resistance
  3. Enhanced unit strength :Facilitates oversized glass design
  4. Enhanced interlayer strength :Enables thinner glass to reduce weight and cost
  5. Superwide 3.2 m width:Improves throughput and reduces costs
  6. Vanceva ® color compatibility:Creates thousands of color opportunities

The disadvantage of DG41 interlayer is, DG41 is still PVB interlayer,when the temperature comes to over 30,the shearing modulus will decrease much and won’t perform its excellent structural performance.So DG41 is only suitable for indoor and low temperature areas.
