Core Applications
Bisphenol A is a critical intermediate in the production of high-performance polymers and industrial materials, with the following key application fields:
Polycarbonate (PC) Plastic Production
As the primary raw material for PC plastic, BPA enables the manufacturing of shatter-resistant, heat-resistant products such as electronic device housings (laptops, smartphones), automotive components (headlight covers, interior panels), and food-contact containers (regulated for safety in most regions).
Epoxy Resin Synthesis
Used to produce epoxy resins for coatings (e.g., can inner linings, industrial anti-corrosion coatings), adhesives (high-strength structural adhesives for aerospace and construction), and electrical insulation materials (circuit boards, transformer windings).
Other Industrial Uses
Raw material for polyether polyols (used in polyurethane foams).
Additive in plasticizers, flame retardants, and UV stabilizers for polymer materials.
Intermediate in the synthesis of specialty chemicals (e.g., antioxidants, dyestuffs).
Quality Standards
Our Bisphenol A products comply with global industrial and safety standards, with typical purity and impurity control indicators as follows:
| Index | Industrial Grade (Typical) | Reagent Grade (High Purity) |
|---|---|---|
| Purity (HPLC) | ≥ 99.5% | ≥ 99.8% |
| Moisture Content | ≤ 0.1% | ≤ 0.05% |
| Ash Content | ≤ 0.01% | ≤ 0.005% |
| Heavy Metal Impurities (Pb, Cd, Hg) | ≤ 10 ppm | ≤ 1 ppm |
| Phenol Residue | ≤ 0.2% | ≤ 0.05% |
Customized specifications are available for specific industrial needs (e.g., low-impurity grades for food-contact material production).
Storage & Handling Guidelines
To ensure product stability and operational safety, follow these storage and handling requirements:
Storage Conditions
Temperature: Store in a cool, dry environment at 15–25 °C; avoid extreme heat (>30 °C) or freezing (<0 °C).
Light: Use opaque containers (e.g., brown glass bottles, HDPE plastic drums with UV protection) to prevent UV-induced degradation.
Humidity: Maintain relative humidity <60%; add desiccants (silica gel, anhydrous calcium chloride) in containers to avoid caking.
Sealing Requirements
Keep containers tightly sealed after each use to prevent moisture absorption and contamination. Avoid using temporary sealing methods (e.g., plastic wrap) that may cause cross-contamination.
Safety Precautions
Wear personal protective equipment (PPE): Dust mask, chemical-resistant gloves, and safety goggles when handling (especially for powder/granular forms).
Ventilation: Ensure good airflow in storage and handling areas to avoid dust or vapor accumulation.
Spill Handling: Clean up spills with inert absorbents (diatomaceous earth, activated carbon); dispose of waste in accordance with local hazardous chemical regulations.
Regulatory Compliance
Global Restrictions: Complies with EU REACH Regulation (Annex XVII) restrictions on BPA in food-contact materials (e.g., banned in infant feeding bottles).
US FDA: Meets FDA guidelines for BPA use in food-contact coatings and plastics (21 CFR 175.300).
China Standards: Complies with GB 4806.6 (safety standards for food-contact plastic resins).
Packaging & Shelf Life
Packaging Options:
Industrial Grade: 25 kg HDPE plastic bags (with inner polyethylene liners) or 500 kg fiber drums (lined with aluminum foil).
Reagent Grade: 1 kg amber glass bottles (sealed with Teflon-lined caps).
Shelf Life: 24 months from the production date (when stored in compliance with the above conditions, unopened).
