Product DescriptionProduct DescriptionNeopentyl Glycol (NPG)Its molecular framework features two hydroxyl groups attached to a neopentyl core, forming a highly branched and symmetrical configuration. This distinct molecular architecture endows NPG with exceptional chemical stability and physical properties, making it a critical intermediate for synthesizing high-performance polymers.It appears as white, free-flowing crystalline flakes or powder, facilitating easy handling and dosing. Compared to conventional linear diols, the primary advantage of NPG lies in its ability to significantly enhance the weatherability, hydrolysis resistance, thermal stability, and mechanical strength of end products. When incorporated into the molecular chains of polyester or alkyd resins, its steric hindrance effect effectively shields ester bonds, substantially reducing the rate of degradation under high temperature, UV exposure, or humid conditions.As a result, polymers derived from NPG exhibit extended service life and superior color and gloss retention. We strictly control every production step from raw materials to finished products, ensuring consistent and reliable quality for each batch of NPG to meet stringent requirements in high-end applications. As a leading NPG manufacturer in China, we are committed to providing high-quality products and professional technical support to drive innovation and development in downstream industries.SpecificationItemSpecificationAppearanceWhite crystalline flakes or powderContent (NPG)≥ 99.0 %Hydroxyl Value650 - 660 mg KOH/gAcid Value≤ 0.05 mg KOH/gMelting Point≥ 125.0 °CMoisture≤ 0.10 %Color (Pt-Co)≤ 15Ash Content≤ 0.01 %Key AdvantagesExcellent Weatherability: Provides outstanding UV resistance and anti-chalking properties, extending the service life of outdoor products.Superior Hydrolysis Resistance: The branched structure protects ester bonds, ensuring polymer stability in humid environments.Good Thermal Stability: High decomposition temperature suitable for high-temperature processing and applications.High Rigidity and Hardness: The symmetrical rigid structure helps increase the polymer's glass transition temperature (Tg) and surface hardness.Excellent Color Stability: Resists yellowing, maintaining the aesthetic appearance of products over time.High Purity and Consistency: Ensures reliable product quality with minimal batch-to-batch variation, guaranteeing stability in downstream production processes.Main ApplicationsHigh-Performance Polyester ResinsPharmaceutical & Pesticide IntermediatesUsed as a key diol raw material for manufacturing durable saturated polyester resins in outdoor powder coatings, coil coatings, and automotive topcoats.Acts as a chemical intermediate in the synthesis of specific pharmaceuticals and pesticides.Polyurethane Elastomers & AdhesivesSynthetic Lubricants & PlasticizersNPG is used to produce polyurethane products requiring extreme hydrolysis resistance, such as industrial tires, seals, shoe soles, and high-performance structural adhesives.NPG is used to synthesize high-grade ester-based lubricant base oils and plasticizers. These products offer outstanding thermal stability and low-temperature performance, making them suitable for engine oils, compressor oils, and PVC products.Storage & PackagingStorage Conditions: Store in a cool, dry, well-ventilated warehouse away from ignition sources and heat. Avoid contact with strong oxidizers and acids.Packaging Specifications: Standard packaging is 25 kg/bag in plastic-lined kraft paper composite bags, ensuring moisture-proof and safe transportation. Customized packaging is available upon request.Shelf Life: 24 months from the production date when stored under recommended conditions.Company ProfileShenyang Xingzhenghe Chemical Co., Ltd.Founded in 2009, Shenyang Xingzhenghe Chemical Co., Ltd. has grown into a nationally recognized high-tech enterprise specializing in the research, development, and production of premium fine chemicals.
