Dragon Grating 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
nine 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 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, and Type
VEX with 10 or less rating.
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, and
Type ISN is none fire-retardant.
IFN is a food grade Isophthalic polyester resin containing
no known harmful elements detrimental to human or animal health.
This special resin is certified by the supplier. The finished
products with this resin are detergent washed and dried. The
IFN is none fire-retardant. And we usually recommend food grade
resin as none fire-retardant as some countries deem fire-retardant
additives as potential harmful ingredients.
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 from corrosion and rust 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, and
ORN type is none fire-retardant.
