石蜡,一种古老而普遍的物质,其历史可以追溯到古代文明,当时人们就已经发现并利用这种天然矿物的独特特性。随着时间的推移,石蜡的应用已经从简单的照明和润滑扩展到了多个领域,展现出其独特的五面特性:防水、绝缘、润滑、成型和防护。在防水方面,石蜡因其良好的密封性而被用于容器的密封,防止水分和气体的渗透。在电气行业中,石蜡作为的绝缘材料,帮助保护电线和设备免受外界影响。此外,石蜡的润滑特性使其在金属加工中发挥重要作用,减少摩擦并延长机械寿命。石蜡还经常被用于各种成型工艺中,如蜡烛和模型制造,提供了易于成型且稳定性强的特点。,石蜡在防护方面也展现了其价值,比如在水果表面形成保护层,延长保鲜期。美国史东毕斯公司,石蜡Paraffin Wax,SP-1275P, NF.吉林供应石蜡

Carnauba wax is considered among the hardest of natural waxes. It has a high melting point, enhances oil retention, produces a very durable film, is valued as a stable co-emulsifying agent and serves as an exceptional polishing aid.
Carnauba Wax is obtained from the leaves of the Brazilian palm tree known as ‘Copernica Cerifera’, also referred to as the "Tree of Life". The Carnauba palm flourishes in northeastern regions within Brazil, and proliferates naturally along riverbanks, streams and damp low-lands.
