Overview
Kingfa Sci. & Tech. Co., Ltd. is a globally recognized Chinese enterprise specializing in the research, production, and sale of modified plastics. Founded in 1993 and headquartered in Guangzhou, the company has grown into one of the largest suppliers of high-performance polymer materials in Asia. Its product portfolio includes over 100 types of modified plastics, serving industries such as automotive, electronics, and appliances. Kingfa operates multiple production bases across China and has established R&D centers in the US, Europe, and India. The company holds numerous patents and complies with international standards like ISO 9001 and IATF 16949, ensuring consistent quality for industrial buyers worldwide.
Physical and Chemical Properties
Kingfa's modified plastics exhibit tailored properties depending on their formulation and intended application. Common characteristics include high tensile strength (typically 40-80 MPa for engineering grades), heat resistance up to 200°C for specialty compounds, and UL94 V-0 flame retardancy for electronics applications. The materials maintain stable performance across temperature ranges from -40°C to 120°C for standard grades. Key additives include glass fibers for reinforcement, mineral fillers for dimensional stability, and halogen-free flame retardants for eco-sensitive applications. The company's proprietary technologies enable precise control over melt flow index (MFI), impact resistance, and weatherability parameters to meet specific industry requirements.
Main Applications
In the automotive sector, Kingfa's materials are used for interior trims (PP compounds), under-the-hood components (PA66), and lightweight structural parts (LFT). The company supplies to major OEMs and tier-1 suppliers globally. For electronics, its flame-retardant ABS and PC/ABS blends meet strict safety standards for appliances and IT equipment housings. The packaging industry utilizes Kingfa's food-contact compliant polymers for containers and films, while the construction sector employs its weather-resistant composites for pipes and insulation. Emerging applications include medical devices (biocompatible grades) and new energy vehicle components (battery casings with UL94 5VA rating).
Safety and Storage
Kingfa's products require standard polymer handling precautions. Granules should be stored in original packaging at <40°C with <50% relative humidity, away from direct sunlight. Most materials are non-hazardous under normal conditions but may emit fumes during processing above recommended temperatures. Material Safety Data Sheets (MSDS) are available for all products, detailing specific handling requirements. Processing areas should have adequate ventilation, especially when working with flame-retardant grades. Personal protective equipment including dust masks and heat-resistant gloves is recommended during material handling and machine operation.
B2B Procurement Guide
Industrial buyers should specify technical requirements including mechanical properties, thermal performance, regulatory certifications (e.g., RoHS, REACH), and color standards. Kingfa offers both standard and custom formulations, with minimum order quantities typically starting at 500 kg for common grades and 1-5 tons for specialty compounds. Lead times range from 2-4 weeks for stock items to 8-12 weeks for custom developments. The company provides technical support for material selection and processing parameter optimization. Payment terms are typically 30% deposit with balance before shipment for new clients, with L/C options available for international transactions.
