Industrial Grade Polyethylene Glycol Plasticizer

Product Specifications

Technical details and manufacturing context for Industrial Grade Polyethylene Glycol Plasticizer

Definition

Industrial Grade Polyethylene Glycol Plasticizer is a high-purity, water-soluble polymer additive used to modify the physical properties of various industrial materials. It functions as a plasticizing agent that increases flexibility, reduces brittleness, and improves processing characteristics in polymer systems. This material is particularly valuable in chemical manufacturing where controlled viscosity, thermal stability, and compatibility with other compounds are essential. Its non-toxic nature and predictable performance make it suitable for demanding industrial applications requiring consistent material behavior. The product is available in a range of molecular weights (200–600 g/mol), which influences its performance in different formulations. Key parameters include viscosity at 40°C (30–120 cSt), hydroxyl value (180–560 mg KOH/g), melting point range (-10 to 20°C), water content (≤0.5% w/w), pH (5.0–7.0), color (≤50 APHA), density at 25°C (1.12–1.14 g/cm³), flash point (≥240°C), acid value (≤0.5 mg KOH/g), ash content (≤0.1%), and purity (≥99.5%). These values are typical for the product category and must be verified for specific grades. The plasticizer is manufactured from ethylene oxide, water, and catalyst compounds, and is used in applications such as coatings, adhesives, and sealants. It is important to note that this directory listing is for reference only; users must confirm model-specific specifications and compliance with relevant standards (e.g., ASTM D4878, D4274, E203, D1287, D1209, D4052, D92, D974, D482) with the legal manufacturer or supplier before use.

Working Principle

Polyethylene glycol (PEG) molecules intercalate between polymer chains, reducing intermolecular forces and increasing chain mobility through hydrogen bonding and molecular spacing. The hydroxyl end groups of PEG form hydrogen bonds with polar sites on the polymer backbone, while the ether oxygen atoms in the PEG chain provide additional interaction sites. This disrupts the regular packing of polymer chains, lowering the glass transition temperature and increasing flexibility. The molecular weight of the PEG affects the degree of plasticization: lower molecular weights (200–400 g/mol) provide more efficient plasticization due to higher mobility, while higher molecular weights (400–600 g/mol) offer better permanence and lower volatility. The plasticizer also influences viscosity, reducing it during processing, and improves the dispersion of fillers and pigments. The effectiveness depends on the compatibility of PEG with the base polymer, which is influenced by the polarity and hydrogen-bonding capacity of both components.

Frequently Asked Questions

What is the typical molecular weight range for this plasticizer?

The number average molecular weight is typically in the range of 200–600 g/mol. Lower molecular weights provide more efficient plasticization, while higher molecular weights offer better permanence. Always confirm the exact molecular weight for your specific application with the supplier.

What are the key parameters to verify before using this plasticizer?

Key parameters include viscosity at 40°C (30–120 cSt), hydroxyl value (180–560 mg KOH/g), melting point range (-10 to 20°C), water content (≤0.5% w/w), pH (5.0–7.0), color (≤50 APHA), density (1.12–1.14 g/cm³), flash point (≥240°C), acid value (≤0.5 mg KOH/g), ash content (≤0.1%), and purity (≥99.5%). These values are typical and must be confirmed for the specific grade.

How does this plasticizer affect the processing of polymers?

It reduces intermolecular forces between polymer chains, increasing chain mobility and flexibility. This lowers the glass transition temperature, reduces brittleness, and improves processing characteristics such as viscosity and filler dispersion. The effect depends on the molecular weight and compatibility with the base polymer.

Is this plasticizer suitable for applications requiring non-toxic materials?

The product is described as non-toxic, but it is essential to verify compliance with specific regulatory requirements for your application. Always check the material safety data sheet and consult with the supplier to ensure suitability for your intended use.
