硅氧烷粘度低，即使是在链长度很长的情
况下
Mw = 250 1 cSt
Mw = 1,000 10 cSt
Mw = 5,000 100 cSt
Mw = 25,000 1,000 cSt
M w = 55,000 10,000 cSt
Chain has a spiral shape Mw = 100,000 100,000cSt
Mw = 300,000 10,000,000cSt

• High free volume – fluidity at high molecular weights
大的分子空间---高分子量时的流动性
• Incompatible with majority of thermoplastics
与大多数热塑性塑料的不相容性
• Low surface tension & energy (lubricant, release agent, aestheticfeel)
低的表面张力和表面能（润滑剂、脱模剂、美感）
• Heat resistant and weather resistant
热稳定性， 耐候性

Ø Siloxane based mold sprays are commonly used in
injection molding to aide in part release
硅氧烷基的脱模喷雾剂常用于注塑加工的脱模
Ø Siloxane fluids or oils (30,000 to 60,000 cSt) are effective
internal and external lubricants
硅氧烷流体是高效的内/外润滑剂
Ø Limitations:
– Handling difficulties 储运/使用的困难
– Surfaceadhesionproblems(migration) 后迁移导致表面附着问题
Ø Innovation from Multibase is use ultra high
molecular weight PDMS (15,000,000 cSt) to
eliminate these limitations.
Ø Multibase创新使用超高分子量PDMS来消除这些缺陷及使用限制
