Description |
|
The
GMT-1800 Series is a range of high density, high melt point
oxidized polyethylene waxes developed by Gong Myoung Technologies
Co. of Korea. The GMT-1800 Series is a harder version
of the GMT-1200 Series i.e. its melt point is higher, molecular
weight is higher and its molecular weight distribution is narrower
therefore the GMT-1800 Series gives harder properties and improved
performance than the GMT-1200 Series, and our policy is to promote
the GMT-1800 Series rather than the GMT-1200 Series however
we will continue to supply the GMT-1200 Series to the existing
customers.
