General description

Pentaerythritol tetraacrylate, Pentaerythritoltriacrylate, and Trimethylolpropane triacrylate mixture is a combination of three acrylate monomers widely used for cross-linking. The Pentaerythritol-based acrylate mixtureoffers advantages such as improved mechanical strength, flexibility, chemical resistance, and UV-curing properties. It finds applications in industries such as automotive coatings, electronics, packaging, and 3D bioprinting.

Application

Pentaerythritol tetraacrylate, Pentaerythritol triacrylate, and Trimethylolpropane triacrylate mixture can be used:

  • As a cross-linking agent to synthesize biodegradable poly (1,3-trimethylene carbonate) (PTMC) networks with improved creep resistance and thermal stability. PMTC networks find application in the field of soft tissue engineering.
  • As a monomer precursor to prepare light-curing dental composites via photopolymerization.
  • To fabricate polymer-dispersed liquid crystal(PDLC) films with low driving voltage, moderately high contrast ratio, and fast response time. These PDLC films are utilized in optoelectronic devices such as OLEDs, FET, and solar cells.
  • As a monomer mixture to prepare 3D bioprinting resins viaphotopolymerization.

Stimuli-responsive microstructures are critical to create adaptable systems in soft robotics and biosciences. For such applications, the materials must be compatible with aqueous environments and enable the manufacturing of three-dimensional structures. Poly(N-isopropylacrylamide) (pNIPAM) is a well-established polymer, exhibiting a substantial
