Description

Ethylene, Polymer With tert-Butyl Acrylate is a copolymer synthesized from ethylene and tert-butyl acrylate monomers. This material is valued for its ability to combine the toughness and chemical resistance of polyethylene with the enhanced adhesion, flexibility, and compatibility imparted by the acrylate component. It serves as a critical performance additive and base polymer in advanced material formulations, particularly where improved surface properties and processability are required. Key industries that utilize this copolymer include adhesives, coatings, plastics modification, and specialty polymer compounding.

Application

• Adhesive Formulations: Acts as a key component in hot-melt and pressure-sensitive adhesives (PSAs) to improve tack, peel strength, and adhesion to low-energy surfaces like polyolefins.
• Polymer Modification: Used as a compatibilizer and impact modifier in polymer blends, enhancing the toughness and flexibility of engineering plastics and polyolefins.
• Coatings & Inks: Serves as a resin in coatings to provide excellent flexibility, weatherability, and adhesion to various substrates, including metals and plastics.
• Wire & Cable Compounds: Employed as an additive in insulation and jacketing materials to improve environmental stress crack resistance (ESCR) and processing characteristics.
• Sealants & Caulks: Imparts durability, elasticity, and long-term adhesion in construction and automotive sealant applications.
• Masterbatch Carrier: Functions as an efficient carrier resin for color and additive masterbatches due to its good compatibility and dispersion properties.

Quality Control

Our Ethylene, Polymer With tert-Butyl Acrylate is manufactured under a stringent quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance in your applications. Key parameters monitored include comonomer content, melt flow rate (MFR), density, and thermal stability. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flames. For long-term storage, consider using an inert atmosphere to prevent potential oxidation.
