Description
Technical field
The present invention relates to a kind of PC compositions, particularly relate to the manufacturer of a kind of PC compositions for packaging material
Method.
Background technology
Merlon (Polycarbonate) is conventional is abbreviated as PC, is a kind of tough thermoplastic resin, it is common that by bis-phenol
A and phosgene production, the most also develop the production method not using phosgene, and realize industry in early 1960s
Changing, realize large-scale industrial production the end of the nineties, be the yield second largest engineering plastics that are only second to polyamide, its title is originated
The CO in portion in the inner3Group.
Merlon water white transparency, heat-resisting, shock resistance, in commonly used temperature, there is good mechanical performance.Impact is strong
Degree height, good stability of the dimension, coloring is good, and electrical insulating property, corrosion resistance, wearability are good, but self lubricity is poor, have stress cracking
Tendency, high temperature facile hydrolysis, poor with other resin-phase dissolubility, be suitable to make instrument finding, insulation transparent part and impact resistance part.
In recent years, the new growing point occurred at packaging field is the water-storing bottle of the various models of repeatable sterilization and use.Due to poly-carbon
It is good that acid esters goods have light weight, shock resistance and the transparency, with indeformable when hot water and corrosive solution carrying out washing treatment and holding
Transparent advantage, some fields PC bottle replaces vial the most completely at present.It was predicted that along with drinking water quality is paid attention to journey by people
Improving constantly of degree, Merlon consumption growth rate in this respect will remain in more than 10%.
