Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 1,3-Butadiene And 2-Propenenitrile is a high-performance synthetic polymer, specifically a terpolymer of methyl methacrylate, butadiene, and acrylonitrile. This material is engineered to deliver a unique balance of properties, including impact resistance, chemical stability, and processability. It is a critical raw material for manufacturers in the plastics, coatings, and adhesive industries seeking to enhance the durability and performance of their formulations.

Application

• Impact Modifier for Rigid Plastics: Used to significantly improve the toughness and impact resistance of PVC, SAN, and other engineering thermoplastics.
• High-Performance Coatings: Serves as a key binder in industrial and automotive coatings, providing excellent weatherability, gloss, and chemical resistance.
• Adhesive Formulations: Imparts strong bonding strength and flexibility in pressure-sensitive adhesives (PSAs) and structural adhesives.
• Polymer Blending & Alloying: Acts as a compatibilizer and modifier to create polymer alloys with tailored mechanical and thermal properties.
• Sealants and Caulks: Enhances elasticity, adhesion, and durability in construction and automotive sealant applications.
• Reinforcement for Synthetic Rubbers: Used to modify nitrile rubber (NBR) and other elastomers to improve oil resistance and mechanical strength.

Quality Control

Our Methyl Methacrylate-Butadiene-Acrylonitrile Terpolymer is manufactured under a stringent quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance in particle size, composition, glass transition temperature, and mechanical properties. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment to guarantee reliable quality and batch-to-batch consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. This polymer is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which may affect performance.
