high performance plasticizer for polysulfidw - Factories
high performance plasticizer for polysulfidw Improved Plasticizers Help to Fill the Gap in Polysulfide Compared to a leading phthalate plasticizer, the newly developed oligomeric dibenzoate plasticizer exhibited equivalent or enhanced performance for characteristics that are highly desirable in polysulfide sealants: viscosity, adhesion, fast
- Does polysulfide sealant increase lap shear strength?
- Using a new oligomeric dibenzoate plasticizer in the B-side of polysulfide sealant resulted in cohesive failure and improved lap shear stress at break, demonstrating good adhesion to substrates such as aluminum and glass. Replacing a phthalate plasticizer with the new plasticizer in the B-side of polysulfide sealant increases its lap shear strength.
- Can Flexible epoxy resin improve the self-healing ability of polysulfide sealants?
- For example, Gao et al. prepared epoxy resin as reactive additives of polysulfide sealant, and showed the result that the flexible epoxy resin are favorable for improving the self-healing ability of the polysulfide sealants [ 3 ].
- Can polysulfide oligomers modify go?
- In this work, the GO was modified by polysulfide oligomers for the sake of introduce abundant block polysulfide oligomers with thiol end-groups, and the functionalized GO (LPO-GO) was loaded into PSR for evaluations including mechanical properties ( Scheme 1 ).
- What does a plasticizer do?
- In the polysulfide sealant, a plasticizer functions to soften the polymer, control the viscosity, and allow for higher filler loading for economy in the 'A' (polymer) side. In the 'B' (catalyst) side, the plasticizer serves as a carrier for the catalyst, ensuring good mixing, viscosity control, and package stability.
- What is a polysulfide sealant?
- Polysulfide sealants are two-part packages for insulated glass and construction. The polymer side of the package contains plasticizer to soften the polymer, control the viscosity, and allow for higher filler loading for economy.
- What is polysulfide rubber used for?
- Polysulfide rubbers (PSR) have been widely used as high performance sealants to line or seal aircraft fuel tanks.
