Casachem™ PEG 3350

Casachem™ PEG 3350 by Thomas Swan is a non-ionic, medium molecular weight polyethylene glycol-based binder, compatibility agent, processing aid, plasticizer, internal lubricant, and dispersion enhancer. It is a clean, biodegradable additive that is versatile across multiple polymer systems.

• It improves blend homogeneity, prevents phase separation and enhances physical properties.
• It provides an effective balance between flow improvement and structural integrity in thermoplastic systems.
• It is solid, waxy flakes or powder that are easy to handle and dose into formulations, with low dusting and good storage stability.
• It is hydrophilic and fully water soluble, offering excellent compatibility with aqueous and polar systems, and making it suitable for both dispersion and cleaning applications.
• It is chemically stable under standard compounding conditions, maintaining performance without degradation or unwanted reactions during high-temperature processing or curing.
• It reduces internal friction during processing, leading to smoother extrusion and molding.
• Its hydrophilic nature promotes better dispersion of fillers and active ingredients, improving the consistency and performance of the final elastomer product.
• In addition, it plasticizes polar polymer matrices, enhancing flexibility and elasticity.
• It is environmentally friendly and safe for use in both industrial and consumer applications, with no long-term accumulation concerns.
• In addition, energy-independent production is ensured through an on-site anaerobic digestion facility.
• Casachem™ PEG 3350 is used in polymer blends, rubber and composite materials.
• Recommended dosage level is 1–5 phr as a processing aid in both natural rubber and synthetic rubber formulations.
• It has a shelf life of 36 months.
