DY-4 is mainly applied in the following many fields:
a. PVC ink, paper ink
b. PVC adhesive, additive for PVC modification
c. strippable coating, leather treatment agent
d. electric cable material, pigment paste and flake for PU, thermal
insulating foaming material, calcium-plastic floor, etc.
DY-4 resin has excellent light and heat stability, but when it is
used outdoors or at higher temperature, the following stabilizers
are suggested to use with it, such as organotin stabilizer without
sulphur, epoxy compound stabilizer, light resistant ultraviolet
Ketone solvents are especially suitable for DY-4 type of bipolymer,
such as acetone, MEK, nadone and isophorone.
Ester solvents have lower solubility for DY-4 resin, such as methyl
acetate, ethyl acetate and butyl acetate etc, so we need to heat
the solution or add ketone solvents into the solution while DY-4
resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as
dichloroethane and diethylene oxide, also can dissolve DY-4
bipolymer, but these kinds of solvent are toxic, they are only used
in special situation.
DY-4 bipolymer is miscible with following resins during the course
Many other types of vinyl chloride vinyl acetate copolymer, PVC
resin, perchloro-ethylene resin, ketone resins, chloroprene rubber,
NBR, polyacrylate, epoxy resin, polyester and petroleum resin etc.
1. Any queries on technology or quality assurance can be inquired
to our company.
2. Should DY-4 resin have been kept over the shelf time, it
shouldn’t mean the resin is invalid, but the user has to test the
relevant properties of DY-4 resin and its finished product before
using it in bulk.
Packaging and Storage:
1. DY-4 resin is usually packaged into the craft paper-plastic
composite bag lined with plastic film
2. Weight is 25Kgs / bag.
3. Resin should be stored in dry place away from sunlight.
1. More appropriate price under the same quality as the one out of
2. Timely and effective service based on quality and technic.
3. Shorter lead time based on requirements from clients
