Butyl methacrylate (BMA) is an organic compound with molecular formula C₄H₉O₂CC(CH₃)=CH₂. It is a widely‑used monomer for manufacturing methacrylate polymers via free‑radical polymerization.
As a flexible plasticizing methacrylate monomer, it serves as a key building block for various copolymer formulations.

<h2>FAQ</h2>
<h3>Q: Why is MEHQ inhibitor added in Butyl Methacrylate?</h3>
A: MEHQ prevents undesired self‑polymerization during storage and transportation. Do not remove inhibitor before formal polymerization process.
<h3>Q: Can we get samples for testing?</h3>
A: Lab trial samples are available; customer covers sample freight cost.
<h3>Q: What documents can you provide for import customs?</h3>
A: COA, MSDS, commercial invoice, packing list; support third‑party test report.
<h3>Q: What is the proper storage requirement?</h3>
A: Store in cool ventilated warehouse below 30℃, sealed, far from heat source and oxidants. Avoid direct sunlight.
