石蜡(Paraffin)是从石油、页岩油或其他沥青矿物油的某些馏出物中提取出来的一种烃类混合物,主要成分是固体烷烃,无臭无味,为白色或淡黄色半透明固体。石蜡是不同分子量的正链饱和烷烃的混和物,可用通式CnH2n+2表示。按照石蜡的物理状态,可以分为液体石蜡、固体石蜡和微晶蜡三大类。石蜡具有价格低廉、来源***、无色无味、理化性能稳定、较大的相变潜热等诸多优点,因此***地应用于医药、包装、建筑、***伪装、工业和农业等领域,近年来在复合相变储能材料上有很多的研究。理化性质外观为白色固体。熔点50℃~70℃,相对密度,平均碳链长为C28~C29,相对平均分子质量为400的品种:20℃固体相对密度~,折射率~,100℃液体相对密度~,折射率~。溶于苯、氯仿、四氯化碳、樟脑油,不溶于甲醇、乙醇和水。性能指标1.熔点石蜡是烃类的混合物,因此它并不像纯化合物那样具有严格的熔点。所谓石蜡的熔点,是指在规定的条件下,冷却熔化了的石蜡试样,当冷却曲线上***次出现停滞期的温度。各种蜡制品都对石蜡要求有良好的耐温性能,即在特定温度不熔化或软化变形。按照使用条件、使用的地区和季节以及使用环境的差异,要求商品石蜡具有一系列不同的熔点。 美国史东毕斯公司STRAHL & PITSCH, INC. 黄蜂蜡Yellow Beeswax, DR-100P,NF。销售石蜡SP173PNF
Microcrystalline waxes are derived from residium. These waxes have very minute crystals (micro-crystals) and are flexible. They have a greater affinity for oil, which is held tightly in the crystalline lattice and does not migrate to the surface.
Microcrystalline Waxes are produced in a variety of melt points, colors, and penetration values. They will add a sensorial benefit to a formulation while improving oil retention.
Functions:
Flexible
Oil Retention
Forms Available:
Slabs
Pastilles
Compatibility:
Microcrystalline Wax is compatible with many vegetable and mineral waxes and a variety of natural and synthetic ingredients.
