World’s first: Polyphenylene Sulfide PPS that can be dyed
After modification and granulation, Polyphenylene Sulfide PPS mostly appears beige, amber yellow, or black.
In December 2023, Kinggor New Materials Factory was the first in the world to develop and produce natural white Polyphenylene Sulfide PPS plastic particles. All performance indicators match well-known brands. Kinggor Polyphenylene Sulfide PPS granules can be dyed, and plastic color masterbatch is added to dye and granulate into colors, yellow, red, blue, orange, green, purple, etc.

Under normal circumstances, in order to meet the needs of specific applications, Polyphenylene Sulfide PPS can be adjusted through modified granulation to improve its properties. The following are some common PPS modified granulation methods and formulas.
PPS modified granulation method:
1. Epoxy resin modification method:
By introducing epoxy resin into the PPS matrix, the mixture is formed and then granulated. This method can increase the toughness and bending strength of PPS while improving its processability and heat resistance.
2. Carbon fiber reinforcement method:
Adding carbon fiber as a reinforcing agent to the PPS matrix can significantly improve the strength, rigidity and thermal conductivity of PPS by changing the content and length of the fibers.
3. Silicone rubber modification method:
Introducing silicone rubber particles into PPS improves the toughness and wear resistance of PPS by increasing elasticity and impact resistance.
4. Environmentally friendly modification method:
Use environmentally friendly modifiers, such as bio-based materials or degradable materials, to reduce the impact on the environment while maintaining the excellent performance of PPS.
