Polyester Polyol for Casting Polyurethane Series EG/AA based
1. Description
This series of polyester polyol is mainly used for producing polyurethane elastomer and the molecular weight can be adjusted according to customer request.
2. Application
This series of polyester polyols is mainly used for producing casting polyurethane especially middle and high hardness pre-polymer. The pre-polymer is mainly used for producing polyurethane sieve plate, caster, roller, pad, rod and molded potting product.
3. Physical properties
| Raw material | Grade | Molecular weight(g/mol) | OH value(mgKOH/g) | Acid value(mgKOH/g) | Water content(%) | Viscosity(75℃ cps) | Chrom(APHA) |
| EG/AA | PE-2010 | 1000 | 107-117 | ≤0.5 | ≤0.03 | 100-200 | ≤30 |
| PE-2020 | 2000 | 53-59 | ≤0.5 | ≤0.03 | 400-650 | ≤30 |
4. Key parameters
The hydroxyl number (OH): is the measure of the hydroxyl group content of gram of polyol.
Hydroxyl value (OH value): is measured by titrating a known mass of polyol against potassium hydroxide (KOH), and is expressed as mg KOH/g.
Lower hydroxyl values indicates lower hydroxyl content and a higher molecular weight for the overall polyol.
OH equivalent weight: is the number of grams of a given product that contains one equivalent of hydroxyl groups (NCO). Equivalent weight = 56100/OH
Molecular weight: is determined by multiplying the equivalent weight by the polyol functionality
The functionality: of the polyol refers to the number of OH groups per molecule.
Increasing the number of OH groups results in greater crosslinking. Greater crosslinking yields stiffer, harder products with enhanced chemical and thermal resistance. Polyols that contain 2 hydroxyl groups are called diols, polyols with 3 functional groups are called triols, polyol groups with 4 hydroxyl groups are called tetrols.
