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.
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.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
