N-PMI应用领域:
  
    PMI作为一种热塑性树脂的优良耐热改性剂,早已广泛应用于先进复合材料基体树脂和胶粘剂的研制,具有可加工性、易成型性、热熔性、强韧性、耐冲击性的优良特性。
    示例:1.ABS和10%的PMI共混,可制得超耐热ABS,不仅耐热性提高30℃以上,并且加工性、热熔性及耐冲击性均好,可代替部分工程塑料应用于汽车工业,因此引起了国内外许多ABS厂家的重视。
            2.在聚氯乙烯中添加PMI 30%,热变形温度可提高54℃;
            3.在聚脂酸乙烯中添加PMI 30%,可提高80℃。
            4.PMI与聚苯乙烯、聚甲基丙烯酸甲脂、聚酰胺等热塑性树脂制成塑料合金,都可以有效地提高各类树脂的性能。
    另外,PMI是一种水中生物回避剂,用含15%的涂料喷涂的钢制品,放在海水中8个月不长海蛎子和海藻。同时,作为广谱杀菌剂,在农药领域也有很好的应用前景,在胶粘剂橡胶助剂等领域亦有广阔用途。
PMI包装、贮存:
    1.产品用纸桶或纸塑复合袋包装。包装含量为20kg、25kg或40kg。

    2.产品应贮存于干燥、通风良好的库房中,远离热源、火源,避免阳光照射。

Use

N-PMI as ABS resin, PVC plastic heat stabilizer and the heat-resistant additives, are widely used in polymer materials, such as polymethyl methacrylate. NPMI is important pharmaceutical intermediate, pesticides intermediate, and dye intermediate.

PMI is used for thermoplastic resin heat modifier and adhesive. Its excellent characteristics including workability, easy molding, toughness, impact resistance.

Example:

1. ABS and 10% PMI blends made of heat-resistant ABS, it is not only heat resistance increased by 30 ℃ or more, and processing, hot melt and impact resistance are good, it can replace part of the engineering plastics used in the automotive industry;

2. If added PMI 30%, in the polyvinyl chloride, the heat distortion temperature can be increased by 54 ℃;

3. PMI and polystyrene, polymethyl methacrylate, polyamide thermoplastic resin made of plastic alloy, it can effectively improve its performance.

In addition, PMI is biological avoidance in the water, with 15% of the coating of steel products, placed in the sea for 8 months, there is not oysters and seaweed. At the same time, it is used as a broad-spectrum fungicide in the field of pesticides, rubber adhesives and other .

Packaging and storage:  Bag content of 25kg, conventional storage in a dry, well-ventilated warehouse.

4. Package & Storage

1).The product should be packed with paper plastic compound bags and the content of every bag is  20kg or 25kg.
2).Avoid of rain and pressure in transportation. The product should be storied in dry ware house and kept away from the heat, fire and sunlight.
