DIE VORTEILE UNSERER FABRIK
ANWENDUNG & VORTEILE VON POLYAMIDHARZ
Test 1. Excellent freezing resistance|
Our polyamide resin is characterized by excellent resistance and high transparency , it can
be well suitable for using in winter and the countries or areas with very low temperature.
Kindly view the above picture of the freezing resistance test:
step 1. the polyamide resins are totally dissolved at 26 degree celsius, the test begins.
(P.S.: Mixing proportion is 40% resin+60% solvent (Xylene:IPA:Ethanol=4:3:3) )
step 2. the liquid is still flowing at -6 degree celsius.
step 3. the liquid becomes to get gelling at -7.6 degree celsius, but the transparency of the
liquid is quite good.
step 4. the gelling liquid was heated back to 26 degree celsius, the transparency is still
1. Our polyamide resin has a excellent resistance, if not, the resin solution will be easy to
gel when the weather is cold.
2. Even if the resin solution gels, it will be still workable of the solution after heating and
3. Our polyamide resin has a high transparency, it ensures the pure colors of printing inks.
Test 2. Good dissolubility|
Our polyamide resin is also characterized by good solubility. Please view the picture of
It takes about 25mins to dissolve the resin with magnetic stirring at 30 degree celsius.
P.S.: Mixing proportion is 40% resin+60% solvent (Xylene:IPA:Ethanol=4:3:3)

Q: What is your test instrument for viscosity? |
A: NDJ-79 made in China. The viscosity tested by NDJ-79 is smaller than tested by
BROOKFIELD made in America under the same conditions.
Q: How long does the polyamide resins totally dissolve in the solvent?
A: Usually, it takes about 30 mins in 50% polyamide resin and 50% anhydrous alcohol solvent under magnetic
stirring at 40ºC. It depends on the temperature and percentage of polyamide resin.
Q: Which one dried more quickly among co-solvent and alcohol-soluble polyamide resin?
A: Co-solvent polyamide resin.
Q: What is the formula weight?
A: About 10,000.
Q: Can you produce according to Air or Sunmide standard?
