Description
Technical field
The present invention relates to a kind of insulation PVC plastic particle.
Background technology
Plastic pellet is being commonly called as of plastic grain, and to be plastics carry out storing with work in-process form, transport and the raw material of machine-shaping.Plastics are family macromolecule materials, are that raw material can obtain ethene, propylene, vinylchlorid, vinylbenzene etc. with oil, and the molecule of these materials can react to each other under certain condition and generate the very large compound of molecular weight, i.e. polymer.
Polyvinyl chloride is a kind of common plastic pellet, is igelite in order to machine-shaping.Pvc material has excellent mechanical and physical performance, snappiness, chemical reagent-resistant performance, low price, and processing characteristics is excellent, is widely used in producing various articles for use, as fields such as footwear, daily necessities, convenient bag, tubing, electric wires.
Along with the progress of society, the performance requriements of people to igelite particle is more and more higher, therefore, needs to improve the igelite particle of routine, to obtain the more superior igelite particle of over-all properties, to expand the application of this plastic pellet further.
Summary of the invention
Goal of the invention: object of the present invention is just to provide a kind of insulation PVC plastic particle.
Technical scheme: for achieving the above object, this invention takes following technical scheme:
A kind of insulation PVC plastic particle, is characterized in that: this plastic pellet comprises following composition by weight:
PVC:100 part;
CPVC:25-30 part;
