|Chinagrate has selected a few resin manufacturers in china to work with.
Some are local companies, others are multi-nationals. As we understand that
resin is critical in providing the corrosion resistance of the grating products,
we have selected the following four different resin choices to ensure every
application is covered for corrosion requirement and cost considerations.
As additives can be added to make the resin fire-retardant, we can make
to the same resin fire-retardant or non fire-retardant.
Type VE is a premium vinyl ester resin. This resin can
perform well even in the harshest environments by withstanding the constant
contact of a wide range of acids and caustics. It¡¯s been used in some of
the most demanding applications such as offshore, waste water, mining and
plating. Type VE type comes with a flame spread rating of 25 or less.
Type IS is a premium Isophthalic polyester resin, This
resin is a very popular choice for most applications due to good corrosion
resistant character and greatly-reduced cost compared with vinyl ester resin
.It¡¯s mostly used in applications where there is a possibility of splash
or spill of harsh chemicals .Type IS comes with a flame spread rating of
25 or less.
Type ISF is also Isophthalic polyester resin but food-grade,
none fire-retardant and can be safely used in food processing.
Type OR is a Orthophthalic polyester resin mostly used
for general purpose. It is an ideal choice in light industrial applications
and in moderate corrosive environments .It offers superior protection form
corrosion and compared with traditional metal gratings .Its low cost makes
it popular in many outdoor general applications such as water treatment,
irrigation application, walkways, and trench covers .OR type comes with
a flame spread rating of 25 or less.
