Product Features
Blue-phase white pigment:
The white color of zinc sulfide has a slight tendency to blue hue. This unique color property makes it whitening when used as a pigment.
High purity:
It has high purity and the zinc sulfide content is greater than 98%, which has better hiding power.
Refractive index 2.37:
The refractive index is an important parameter of optical materials. The refractive index of zinc sulfide is 2.37, which is at a relatively high level. It is the non-toxic white pigment closest to titanium dioxide.
High thermal conductivity:
Its thermal conductivity is 27W/(m·K), which is higher than that of aluminum oxide. It can be used in some thermal conductive inks or coatings.
Excellent heat resistance:
After high-temperature calcination, it is resistant to high temperatures and does not decompose when used. It is very stable when used below 350℃, and is suitable for most glass fiber reinforced plastics and special high-temperature plastics.
Low Mohs hardness:
The Mohs hardness is only level 3, which can reduce the wear of plastic processing on equipment. Zinc sulfide can reduce the wear and scratch of pigment on glass fiber in color matching, better maintain the length of glass fiber, and improve various mechanical properties of modified plastics.
Application
Ambition Material's High Performance Plastic Zinc Sulfide is widely used in special engineering plastics such as PTFE, PPO, PSU, PEEK, PI, PPS, and LCP. It can better exert the special plastics' high temperature resistance, corrosion resistance, wear resistance, and high strength, and extend the service life of the products. It can be used to prepare long afterglow luminescent materials, and can also be used as a non-fluorescent brightener. It has a whitening effect and can be used with a fluorescent brightener to improve the efficiency of the fluorescent agent.
Production Technology
Ambition Material uses zinc sulfate and sodium sulfide as raw materials to react and synthesize zinc sulfide, and then goes through filter pressing and dehydration, flash drying, high-temperature calcination, crushing and packaging to complete the production process of zinc sulfide.
ZnSO4+Na2S =ZnS↓+Na2SO4
Packaging
25 kg/bag. In order to obtain the best possible results, we recommend that the products be stored in a normal temperature, dry and moderate air humidity environment, and the products should be kept unstacked and used within 12 months.

FAQ
Q: Which well-known chemical industry product is Ambition Material's High Performance Plastic Zinc Sulfide benchmarked against?
A: SACHTOLITH L.
Q: In the production of high-temperature plastics, will the addition of Ambition Material's high-performance plastic zinc sulfide affect the high-temperature resistance and color of the product?
A: Our High Performance Plastic Zinc Sulfide has not been surface treated, and the zinc sulfide content is increased during internal control, so it has better hiding power and color reduction power. Since it has not been surface treated with organic matter, there will be no breakage of organic macromolecules when used under high temperature conditions, and it will not affect the color of the product.
Q: Is zinc sulfide a fluorescent brightener?
A: Zinc sulfide is not a fluorescent brightener. Zinc sulfide itself does not have fluorescent properties, but it can absorb some ultraviolet and red light and is a blue-white pigment, thereby improving the whiteness and brightness of the material. In some applications, zinc sulfide can be used as a non-fluorescent brightener, reducing the need for fluorescent brighteners, or completely replacing fluorescent brighteners to meet specific application requirements.
Q: Can zinc sulfide replace titanium dioxide?
A: Zinc sulfide generally cannot completely replace titanium dioxide. Zinc sulfide and titanium dioxide are two different white pigments. Zinc sulfide has unique application advantages in glass fiber modified reinforcement materials, UV light curing coatings, thermal conductive coatings and anti-mold coatings.
