Plastic additives requirements

2013-07-30 by seoer8

The main requirements of the plastic additive are:
① Efficient: applications in plastics processing and can effectively play its proper function. Selection should be based on the additive mixing with the comprehensive performance requirements.
② Compatibility: synthetic resin with better compatibility.
③ Persistence: in the plastic processing and application process is not volatile, non-bleeding and non-migratory and non-leaching.
④ Chemical stability: in the plastic processing and application process does not decompose with the synthetic resin and other components of the chemical reaction.
⑤ Non-toxic: no toxic effects on the human body.
⑥ low prices. Add a way to add an additive depends on: the physical form of synthetic resin and melt characteristics;pvc additive physical form and concentration; additive compounds, the dispersion and solubility; compounds, the ultimate physical condition. Add o'clock

High-speed mixing, mixing and extrusion processes. The effect additives may be added, in addition to depending on their mechanism of action, but also depends on the correct order of addition.
