《GB/T 37197-2018乙烯-乙酸乙烯酯（EVAC）树脂》由TC15（全国塑料标准化技术委员会）归口，TC15SC1（全国塑料标准化技术委员会石化塑料树脂产品分会）执行，主管部门为中国石油和化学工业联合会。
Introduction
1. Background and significance of the standard
GB/T 37197-2018 "Ethylene-vinyl acetate (EVAC) resin" was drafted according to GB/T1.1-2009 rules, proposed by the China Petroleum and Chemical Industry Federation, and managed by the National Plastics Standardization Technical Committee. This standard applies to ethylene-vinyl acetate copolymers (EVAC resins) obtained by polymerization under high pressure with ethylene and vinyl acetate as monomers, in which the vinyl acetate content ranges from 3% to 40% (mass fraction). The formulation of this standard provides unified technical specifications for the production, inspection and application of EVAC resins, ensuring the consistency and reliability of product quality.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 37197—2018 | Comparison standards | Difference analysis |
|---|---|---|---|
| Classification and naming | In accordance with GB/T 30924.1—2016 | Industry unified standards | No obvious differences, remain consistent |
| Technical requirements | Covering technical indicators of resins for injection molding, films, cables and hot melt adhesives | Single product standard | More comprehensive, suitable for applications in multiple fields |
| Test Methods | Combining multiple test methods (such as infrared spectroscopy, titration) | Single detection method | More scientific and more operational |
3. Implementation suggestions and application cases
Implementation suggestions:
- Enterprises should establish a complete quality management system to ensure compliance with standard requirements.
- Strictly control the raw material ratio and process parameters during the production process, especially the precise determination of vinyl acetate content.
- Strengthen the calibration and maintenance of test equipment to ensure data accuracy.
Application Case:
A cable manufacturing company uses EVAC 28 KN D045 resin to produce high-voltage cable insulation layers, which shows excellent electrical properties and mechanical strength in actual applications, meeting industry standard requirements. This case shows that EVAC resin has important application value in the cable field.
