Plastic, glass transition temperature

Plastic, glass transition temperature (Tg) directly affect the migration speed of antistatic agent. When the Tg below room temperature, because the chain of molecular motion, making internal antistatic agent easy to migrate to the surface. Plastics such as PE and PP anti-static properties easier to maintain. For Tg above room temperature of plastics, such as PS, PVC, ABS, etc, because chain molecules at room temperature in a frozen state, antistatic agent is difficult to migrate to the plastic surface.

Plastic crystallinity

In General, mixing non-crystallization-type antistatic agent in plastic parts, plastic and micro-granulated mixed state. Plastic crystals on the surface of the antistatic agent migration also has a great impact. The higher the crystallinity. Surface migration more difficult and worse the anti-static effect
