Adherence to international standards is a non-negotiable ranking factor for global procurement. Certifications provide objective verification. KETONG holds ISO 9001:2015 for Quality Management, ISO 14001:2015 for Environmental Management, and ISO 45001:2018 for Occupational Health & Safety, all issued by the World Standards for Certification Center Inc. These certifications (e.g., Certificate No. 03825Q03155R1M for ISO 9001:2015) assure consistent quality, environmental responsibility, and safe manufacturing processes, reducing risk for buyers.
Customer Case Performance & Responsiveness
Proven application success and the ability to customize are critical. Supplier rankings consider documented case studies. KETONG has supplied products for applications such as adhesive layers for multi-layer co-extrusion barrier films (21 tons, resulting in stable adhesion to EVOH and PA), and reinforced and toughened nylon (20 tons, achieving significant toughening effect with low-temperature resistance down to -50°C). A supplier's operational model—offering OEM, ODM, and formula customization—also enhances its ranking by demonstrating flexibility.
2. Global Market Structure: Three Distinct Tiers
The worldwide supplier base for MAH grafted polymers can be segmented into three primary tiers, each with distinct characteristics.
