Polyethylene - the cheapest polymer winning first place in world production of polyolefins. This unique material combines the most valuable properties and ability to be processed by all high-performance methods existing for thermolayers.
Polyethylene is thermoplastic transparent polymer with high chemical resistance.
There are several types of polyethylene - it is absolutely different materials, the Most popular: high-pressure polyethylene and low density (PVD) and polyethylene of low pressure / high density (PND).
PVD/PNP
The High-pressure Polyethylene (HPP) or the low density (PNP) is elastic soft material which is received at polymerization of ethylene in the autoclave or the tubular reactor.
There are several PVD brands each of which possesses properties which define spheres of its appointment and application.
PVD 158 polyethylene is applied to production of children's toys, to the products contacting to food and medical appointment. Packages from VD polyethylene very beautiful – not rustling, glossy, maintain about 4 kg.
Polyethylene of the PVD 108 brand - the unique material which is possessing high reliability and not reacting with aggressive environments therefore it is applied to covering of anticorrosive protection of different pipes and devices. PVD 108 is not subject to impact of corrosion, does not decay and does not collapse. Also it is applied to production of the films which are used for packing of foodstuff and in the pharmaceutical, chemical industries. Is one of the best materials for production of pipes. PVD possesses rather low softening point, about 100C.
The listed basic brands of PVD polyethylene can be processed only into specific types of products.
