Additive Masterbatch

HD-BD01 is a polyethylene based oxo-biodegradable masterbatch developed primarily for use in the packaging film industry but which has subsequently fourd use in a broad range processes where it has been used to introduce an oxo-biodegradable characteristic to polymeric products.

The carrier shows excellent compatibility with many polyolefinic based processes and exhibits good high temperature stability although, as with all polyethylene products, long times at high temperatures(>270c)should be avoided.

The product is suitable for direct food contact applications under EC and FDA regulations.

HD-BD01 contains a metal ion prodegradant system. Formulated to offer a high level of controlled thermodetradation in the finished product following a period of photoexposure. It also utilises a secondary biodegration promoter that impacts a biodegradable charateristic following the initial oxidation. The product has a minimal effect on physical properties compared with the use of alternative products.

These active ingredients impart a high level of photo and thermodegradability to the finished article but incorporate a unique control system that gives a readily predictable dwell time before the degradation reaction commences.

The total additive package enhances the degradation and the breakdown of polymer subsdtrates, leaving a microfragmented structure which is then subsequently available for biodegradation.

Addition rates are dependent on the precise biodegradable properties required within each particular application. However, addition rates of between 1 and 2%would normally be used.

The product should be premixed with the polymer feedstock or metered in at the feed hopper. Processing conditions should generally be kept the same as those used for the unmodified polymer feedstock.

HongDa masterbatch is one of the most famous masterbatch manufacturer in north China, which is located in Industrial area in Tianjin. We have an experience of more than 10 years in both domestic and oversea market. Now we have a monthly production with 300 tons.

We established our new workshop last year and imported 2 more new production line, in order to meet more clients' demands. Now we just set up our first branch office in Canada last month.
