Hidispersion zno-80/product description
Use characteristics hidispersion zno-80 is a special grade of zinc oxide particularly suitable for the rubber industry. Due to its epdm elastomer bound form, the absorption of humidity from the atmosphere during storage is prevented. In comparison to extrusion compounds containing powdered zinc oxide, those with hidispersion zno-80 provide smoother profiles. This is due to the more homogeneous dispersion of hidispersion zno-80. A slight increase in modulus and tensile strenghth usually occurs; elongation at break is also improved. Hidispersion zno-80 prevents the heat swell which normally occurs when powdered zinc oxide is used in cr mixes.

Jining zhong yi rubber plastic co., ltd, one of a member of plastics processing industry association and special committee of color master batch & dyestuffs industry association, located at rencheng economic development zone, jining, shandong province. The factory covers 30, 000 square meters with workers 120 and engineers 10 included.
The company owns advanced co-rotating twin-screw extruder production lines and perfect technology and quality management system which combined with research & development, production and marketing. Five groups of our products are color master batch, functional master batch, filler master batch, special modified plastics and rubber pre dispersion processing promoters with an annual production capacity of 30, 000 tons in total.
With masterbatch fasting development , we continuely build new workshop for rubber compound production line and pp/ps flateware processing line with professional tech people and worker .Here we appreciate to joint with our honor customers to develope very well in future.
Based on our own professional technical advantages, we build long term cooperative relationships with qingdao university of science and technology and resin research institute of qilu petrochemical co., ltd., which enhances our new product development and speed up conversion from technology to production of filler masterbatch, white and black masterbatch, uv stabilizer materbatch and more than 50 types masterbatch .
We have set up our leading status in related industries in china. Furthermore, many technologies are first invention in china and a lot of types products replaced the same types imported. Now we are tracking on the development trend of new technology to continue our new product development.

Physiological property:
Refer to material safety date sheet (msds)
Technology:
Rubbe accelerator pbo-80 is a special pre-dispersed zinc oxide that apply to rubber industry. Its combined elastomer will prevent moisture absorption in storing.Because of pre-dispersed more evenly, the rubber contains pbo-80 makes product more smooth compare to extrusion rubber made by powder lead oxide.Generally, the tensile and stretch of the pre-dispersed pbo-80 contained vulcanized rubber will be prompted, and elongation at break improved meanwhile.
Process:
Normally, powder pbo hardly disperse evenly under processing temperature, which cause vulcanization activity declined as well as rubber' static mechanical properties and dynamic fatigue.However, pre-dispersed pbo-80 , because of selection and control of grain diameter, and making pre-dispersed by using its carrier of epr(ethylene propylene rubber)and dispersed surfactants, can keep the best activity of components and dispersed evenly when doing the feeding process during mixing.What's more, pre-dispersed pbo-80 has advantages in the followed:
1.Its granule shape prevents blocking under storage environment.
2.Easy mixing
3. Good flowing
4.No dusty
5.No wastage in feeding
6.Improve the stabilization and homogeneity of each batch mixed rubber
7.Avoid the thermal expansion in feeding of powder zinc oxide.
It is suggested feeding at the end of mixing process.
Dosage:3 - 8 phr
Application:
Used to almost all rubber products to improve the statics and dynamic ability.
