z4导热膏就是硅脂，也属于导热硅脂。

导热硅胶通常也叫导热RTV胶，可以室温固化，有一定的粘接性能。

导热硅胶是硅橡胶的一种，属于单组分室温硫化的液体橡胶。一旦暴露于空气中，其中的硅烷单体就发生缩合，形成网路结构，体系交联，不能熔化和溶解，有弹性，成橡胶态，同时粘合物体。而且一旦固化，很难将粘合的物体分开。

导热硅脂是一种导热介质，是以有机硅为基础原料，添加各种辅材，经过特殊工艺合成的一种酯状物高分子复合材料。

是一种白色或灰色的导热绝缘黏稠物体，该物质有一定的黏稠度，没有明显的颗粒感。无毒、无味、无腐蚀性，化学物理性能稳定而且具有优异的导热性、电缘性、耐高温、耐老化和防水特性。

通常情况下，导热硅脂不溶于水，不易被氧化，还具备一定的润滑性和电缘性。

Z4 thermal conductive paste is silicone grease, which also belongs to thermal conductive silicone grease.

Thermally conductive silica gel, also known as thermally conductive RTV adhesive, can be cured at room temperature and has certain bonding properties.

Thermal conductive silica gel is a kind of silicone rubber, which belongs to one component room temperature vulcanized liquid rubber. Once exposed to the air, the silane monomer will condense and form a network structure. The system is cross-linked, can not melt and dissolve, elastic, form rubber colloidal state, and bond the object at the same time. And once cured, it is difficult to separate the bonded objects.

Heat conductive silicone grease is a kind of heat conductive medium. It is an ester polymer composite synthesized by special process with silicone as the basic raw material and various auxiliary materials.

It is a white or gray thermal conductive and insulating viscous object. The material has a certain viscosity and has no obvious sense of particles. Non toxic, tasteless, non corrosive, stable chemical and physical properties, and has excellent thermal conductivity, electrical insulation, high temperature resistance, aging resistance and waterproof characteristics.

Under normal circumstances, the thermal conductive silicone grease is insoluble in water and is not easy to be oxidized. It also has certain lubricity and electrical insulation.
