Thermal Stability
热稳定性
Thermal analysis (TGA) shows no obvious weight loss up to 350℃; At 375℃, there is about 2.5% weight loss; and at
400℃, it begins to decompose (about 7% weight loss).
热解重量分析结果显示, 350℃时, Glycolube P 仍没有明显的重量损失; 375℃时, 重量损失约2.5%;
至400℃时, 它才开始分解(重量损失约7%).
Suggested applications
应用范围
Glycolube P is an effective lubricant for many polymer compounds in both extrusion and molding processes. It’s
recommended for use as a mold release agent in polycarbonate, thermoplastic polyesters and other thermoplastics.
Glycolube P’s outstanding thermal stability allows its use in these systems without fear of degradation. Moreover, it
can notablely improve transparence and surface fineness.
在挤出和塑模加工过程中，Glycolube P 对很多聚合物来说都是一个有效的润滑剂;推荐用于PC(聚
碳酸酯)、热塑性聚酯(PET,PBT 等)、PPO、PPS 及其它的热塑性塑料。Glycolube P 突出的热稳定性，
使它可用于此类体系的加工过程，不用担心发生降解;而且, 它可以显著改善透明度及表面光洁度。
Used as an external lubricant in polycarbonate and rigid PVC as well as many other polymer systems, Glycolube P is
a highly efficient lubricant allowing its use at lower concentration than most conventional lubricants. Typical loading is
0.1-1.0%. Glycolube P is recommended wherever a combination of outstanding thermal stability and excellent release

properties are needed.
作为PC、硬PVC 和其它聚合物体系的外润滑剂时，Glycolube P 的性，允许它的使用量低于大
多数传统的润滑剂，典型用量0.1-1.0%. 当需要同时具备热稳定性与优异的脱模性能时，
Glycolube P是一个的选择。
