Description

Poly-Nipam CAS NO 90398-43-9 is a high-purity, synthetic polymer derived from N-isopropylacrylamide (NIPAM) monomers. This advanced material is valued for its unique, temperature-responsive properties in aqueous solutions, undergoing a reversible phase transition at a specific lower critical solution temperature (LCST). It is essential for researchers and manufacturers in life sciences, advanced materials, and controlled-release technology who require precise and tunable polymer behavior. Its consistent quality and performance make it a critical component for developing innovative, smart applications.

Application

• Biomedical Research & Drug Delivery: As a key component in the synthesis of thermosensitive hydrogels for controlled drug release systems and tissue engineering scaffolds.
• Smart Materials & Coatings: For creating surfaces with switchable wettability, temperature-responsive filters, and actuators.
• Diagnostics & Bioseparation: Utilized in affinity precipitation and cell detachment substrates due to its reversible solubility transition.
• Cosmetics & Personal Care: Employed in formulating advanced skincare products that offer temperature-triggered viscosity changes for enhanced sensory profiles.
• Agriculture: Potential use in developing smart delivery systems for agrochemicals, enabling controlled release based on environmental temperature.
• Academic & Industrial R&D: Serves as a fundamental polymer for studying stimuli-responsive polymer physics and chemistry.
