KETONG MAH Grafted Polymers: Verified Application Results
KETONG MAH Grafted Polymers: Verified Application Results
Shenyang Ketong New Materials Co., Ltd., founded in 2003, is a high-tech enterprise specializing in the research, development, and production of functional polymer materials. With over 20 years of industry experience, the company operates a 30,000-square-meter factory and a new facility completed in 2023, bringing a combined annual production capacity of 60,000 tons. KETONG focuses on three product categories: compatibilizers, toughening agents, and adhesive resins, all based on maleic anhydride (MAH) grafted polymer technology. The company holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, ensuring quality, environmental, and occupational health standards are met throughout production and marketing.
Industry Challenge: Consistent Performance from a Reliable Supplier
Procurement professionals evaluating suppliers of maleic anhydride grafted polymers require more than just product specifications—they need verified performance in real-world applications. Variances in grafting level, melt flow, and residual odor can directly impact the final compound's mechanical properties, processability, and regulatory compliance. A supplier that can demonstrate repeated success across diverse applications offers a lower risk profile and shorter qualification cycle.
KETONG's Manufacturing and Quality Framework
KETONG's two factories in Shenyang, Liaoning, occupy over 30 acres. The original plant has an annual capacity of 50,000 tons, while the new plant built in 2023 is designed for 60,000 tons per year. The company employs 130 people, including 8 R&D engineers, and operates more than 10 imported production lines. KETONG provides OEM, ODM, OBM, and other customization services, with a monthly capacity of 5,000–6,000 tons. The quality management system is certified under ISO 9001:2015 (certificate numbers 03824Q412511R0S and 03825Q03155R1M), and the environmental and occupational health systems are similarly certified.
Step-by-Step Engagement Process
- Requirements Consultation – Client shares target polymer system, desired performance (toughening, compatibilization, adhesion), and regulatory needs.
- Formula Customization – KETONG's R&D team adjusts MAH grafting level, melt flow rate, and carrier resin to match the application.
- Production and Quality Control – Random sampling inspection is performed. Products are tested for MAH content, MFR, density, and mechanical properties.
- Packaging and Delivery – Demand-driven scheduling ensures lead times align with client project timelines. MOQ is customizable on demand.
- After-Sales Support – Return, replacement, and refund policies apply for quality issues.
Proven Application Cases
Case 1: Glass Fiber Reinforced Polypropylene
A modified polymer material manufacturer sourced KETONG's Low-Odor PP Compatibilizers (models LEP-1B and LEP-1K) for glass fiber reinforced polypropylene and mineral filled polypropylene. The project achieved remarkably enhanced impact resistance in the final polymer compounds. Key highlights include low VOC emission and enhanced aging resistance of the modified materials. The project was implemented in China, the United Kingdom, India, Vietnam, and Italy, with a supply of 22 tons over one year.
Case 2: Reinforced and Toughened Nylon
For a nylon toughening application, KETONG supplied KT-916K (POE-g-MAH, high MAH) at 20 tons over one year to clients in the UK, India, Vietnam, and China. The result was a significantly improved toughening effect. Key highlights include stable and reliable performance with low-temperature resistance down to -50°C.
Case 3: Multi-Layer Co-Extrusion Barrier Films
An adhesive resin application used KETONG's KT-NJP2201 (PE-g-MAH, low MAH) for multi-layer co-extrusion barrier films. The product demonstrated excellent adhesion to EVOH and PA, fewer gel spots, and good transparency. Results include stable adhesion performance in the co-extrusion process, meeting food packaging barrier and safety requirements. The 21-ton project was delivered over one year to clients in Asia and Europe.
Case 4: Glass Fiber Reinforced PP with PP-g-MAH
A separate project involving glass fiber reinforced polypropylene used KETONG's PP compatibilizers (models KT-1, KT-1D, KT-1H). The project achieved remarkably enhanced impact resistance in the final material. Key highlights include excellent material impact strength retention, good processability, and significantly improved compatibility between materials.
