Aromatic Polyester Polyol from XINFA: Certified Specifications and Application Selection for Global Buyers
Aromatic Polyester Polyol from XINFA: Certified Specifications and Application Selection for Global Buyers
Introduction
Aromatic Polyester Polyol is a key raw material for polyurethane rigid foams used in thermal insulation, structural panels, and industrial coatings. For global buyers evaluating suppliers, verifying product specifications, certifications, and application fit is critical to avoid formulation failures, regulatory non-compliance, or supply chain disruptions. XINFA (Hengshui Xinfa Polyurethane Materials Co., Ltd.), established in 2010 and located in the Salt Chemical Circular Economy Park in Jizhou City, is a high-tech enterprise specializing in the research, development, and production of polyester polyols and polyurethane catalysts. XINFA offers a full range of aromatic polyester polyols backed by ISO certifications and an annual production capacity of 50,000 tons. This article provides a detailed reference for procurement professionals, covering key specifications, certification details, application guidance, and selection criteria.
Problem Definition
Buyers sourcing Aromatic Polyester Polyol often face three challenges: (1) verifying that the product meets claimed performance parameters such as hydroxyl value, acid value, and viscosity; (2) ensuring the supplier holds valid third-party certifications (ISO 9001, ISO 14001, ISO 45001) for quality, environmental, and occupational health management; and (3) selecting the correct grade for specific foam applications (spraying, sandwich panels, pipes, etc.). Without clear, fact-based information, procurement decisions risk costly rework, production downtime, or failed compliance audits.
Industry Background
The global aromatic polyester polyols market was valued at USD 1.9 billion in 2026 and is projected to reach USD 2.8 billion by 2033, growing at a CAGR of 5.9% (Persistence Market Research). Asia Pacific dominated the overall polyester polyol market with a 43.7% revenue share in 2024, with China expected to grow at the highest CAGR of 5.2% through 2033 (Grand View Research). The EU Energy Performance of Buildings Directive (2024/1275) further drives demand for high-performance insulation materials, where aromatic polyester polyols are a volume anchor for rigid PU and PIR foams.
Detailed Solution: XINFA Aromatic Polyester Polyol Series
Phthalic Anhydride-Based Polyester Polyol (Aromatic Type)
XINFA produces a series of phthalic anhydride-based aromatic polyester polyols under the XF brand. These are formulated using raw materials PA (phthalic anhydride), PTA, AA, DEG, and GLY. The following models are designed for spraying insulation, sandwich panels, polyurethane pipes, PU wood imitation, and home appliances:
| Model | Hydroxyl Value (mgKOH/g) | Acid Value (mgKOH/g) | Moisture (%) | Viscosity (cPs @25°C) | Typical Application |
|---|---|---|---|---|---|
| XF-3152 | 315±15 | ≤2.0 | ≤0.1 | 3000±500 | Spraying insulation, sandwich panels |
| XF-2412 | 260±10 | ≤1.5 | ≤0.1 | 6000±1500 | Pipe insulation, continuous panels |
| XF-1752 | 175±10 | ≤1.0 | ≤0.1 | <5000 | Wood imitation, low-viscosity systems |
| XF-2002 | 195±5 | ≤1.0 | ≤0.1 | 10000-30000 | Home appliances, high-strength foam |
All models are manufactured in ISO 9001:2015-certified facilities, with production quality monitored through 100% testing protocols.
Certification Compliance
XINFA holds three management system certifications issued by Beijing United Intelligence Certification Co., Ltd.:
- ISO 9001:2015 (Cert. No. 04322Q31390R1S) – Quality Management System for production of oligomeric polyester polyols.
- ISO 14001:2015 (Cert. No. 04326E01332R101) – Environmental Management System for production and related activities.
- ISO 45001:2018 (Cert. No. 04326S01211R101) – Occupational Health and Safety Management System.
These certifications cover all aromatic polyester polyol models (XF-3152, XF-2412, XF-1752, XF-2002) as well as other product families, ensuring consistent quality and regulatory compliance for global buyers.
Step-by-Step Selection Guide for Aromatic Polyester Polyol
- Determine end-use application – Spraying foam, sandwich panel, pipe insulation, appliance foam, or wood imitation. Each requires specific reactivity and viscosity.
- Match hydroxyl value range – Higher OHV (315±15) gives higher crosslink density and compressive strength; lower OHV (175±10) provides more flexibility. Select according to foam hardness requirements.
- Verify acid value and moisture – Low acid value (<2.0) and moisture (<0.15%) are essential for stable foaming and long-term storage. XINFA products meet these limits.
- Check compatibility with blowing agent – For pentane-blown systems, request specific grades like XF-2402N or XF-2020 from the Pentane System series (not part of the aromatic series but available). XINFA offers dedicated pentane-system polyester polyols for appliance and panel foaming.
- Request a sample test – XINFA provides samples (MOQ 1 MT for bulk orders, sample available upon request) with technical support to adjust formulation.
