性质:
本品为微黄色透明液体,可用客户指定的溶剂稀释。不溶于水,溶于多数有机溶剂,闪点:12.5℃ (闭皿),18℃(开皿),沸点:109℃,凝固点:-40℃。粘度(20℃):0.9mPa.s 。
用途:
1.用作乙烯基、双烯基单体的聚合引发剂,推荐的交联温度范围为180-240 ℃。在菅式法和釜式法高压聚乙烯聚合工艺中,它是一种常用的引发剂,交联的温度范围为240-280 ℃。
2、为不饱和聚酯的高温固化剂。
3、是二烯类橡胶的有硫化剂,适合于厚橡胶制品硫化。拉伸强度,伸长率和耐压缩和变形性能好,获FDA批准,适合于绝大多数橡胶、聚氨酯弹性体、硅橡胶的硫化,可获得白色和各种鲜艳色彩的橡胶制品。
4、用于聚丙烯高速纺丝(丙纶)工业中,做分子量调节剂(用于降温母粒生产中)。具有分子量分布窄,熔体指数高,纺丝均匀的特点,是聚丙烯修饰中使用的优良降解剂,在聚丙烯中加入该品,可制成控制流变聚丙烯,提高流动性,使聚丙烯快速模压成为可能,同时可减少模压产生的形变。经过改性的聚丙烯可制成薄膜料。
5、用于油品添加剂和变压器油的降凝剂。
包装及运输:
我厂的标准包装为20公斤的聚乙烯包装。也可根据客户的要求的包装尺寸供货,客户可在订货时提出要求。
Property:
This product is a slightly yellow transparent liquid, which can be diluted with the solvent specified by the customer. Insoluble in water, soluble in most organic solvents, flash point: 12.5 ℃ (closed dish), 18 ℃ (open dish), boiling point: 109 ℃, freezing point: -40 ℃. Viscosity (20 ℃): 0.9mPa. s.
Purpose:
1. As a polymerization initiator for vinyl and dienyl monomers, the recommended crosslinking temperature range is 180-240 ℃. It is a commonly used initiator in high-pressure polyethylene polymerization processes using the Kan method and the kettle method, with a crosslinking temperature range of 240-280 ℃.
2. It is a high-temperature curing agent for unsaturated polyester.
3. It is a vulcanizing agent for diene rubber, suitable for vulcanizing thick rubber products. Good tensile strength, elongation, compression and permanent deformation resistance, approved by FDA, suitable for vulcanization of the vast majority of rubber, polyurethane elastomers, and silicone rubber. It can obtain white and various bright colored rubber products.
4. Used in the high-speed spinning of polypropylene (polypropylene fiber) industry as a molecular weight regulator (used in the production of cooling masterbatch). It has the characteristics of narrow molecular weight distribution, high melt index, and uniform spinning, and is an excellent degradation agent used in polypropylene modification. By adding this product to polypropylene, it can be made into controlled rheological polypropylene, improve flowability, and make rapid molding of polypropylene possible, while reducing deformation caused by molding. Modified polypropylene can be made into thin film materials.
5. Used as oil additive and pour point depressant of transformer oil.
