Polymers & Resins covers both finished polymers and the reactive components used to make thermosets and coatings. Listings range from commodity and engineering plastics such as Acrylonitrile butadiene styrene to epoxy chemistry, acrylate monomers and additives. Examples include 1,4-Butanediol diglycidyl ether, a reactive epoxy diluent, 1,2-Cyclohexanedicarboxylic anhydride as a hardener, 2-Hydroxypropyl methacrylate, Benzyl acrylate and the water-compatible photoinitiator 2-Hydroxy-4′-(2-hydroxyethoxy)-2-methylpropiophenone.
Formulators judge these materials by epoxy equivalent weight, acid or hydroxyl value, viscosity and inhibitor content. Acrylates are supplied with inhibitors such as MEHQ to prevent premature polymerisation, so storage with some air headspace is normal. For research polymers, molecular weight and polydispersity are the defining figures.
Products are packed in drums, pails or bottles according to volume, with light-proof containers for photoinitiators. Each lot ships with a COA and SDS. Samples are available for formulation trials before you commit to bulk quantities.
Polymers & Resins: questions buyers ask
Why do acrylate monomers need oxygen during storage?
Common inhibitors such as MEHQ only work in the presence of dissolved oxygen. Storing acrylates under pure nitrogen can deactivate the inhibitor and allow runaway polymerisation. Keep containers with some air headspace, away from heat and light, and use stock within the recommended period.
What is a reactive diluent in epoxy formulations?
A reactive diluent is a low-viscosity epoxy compound, such as 1,4-butanediol diglycidyl ether, added to thin a resin. Unlike a solvent, it reacts with the hardener and becomes part of the cured network. It improves flow and wetting but can lower heat resistance if used in large amounts.
How do I choose a photoinitiator for UV curing?
Match the photoinitiator's absorption to your lamp output, often 365 nm for mercury lamps or 395 to 405 nm for LEDs. Consider film thickness, pigmentation, yellowing and water solubility. Hydroxyethoxy-substituted types are often used in waterborne and biomedical hydrogel formulations because of their lower toxicity.
