The increase of zinc oxide amount has little effect on E2. When zinc oxide increased from 1 phr to 2 phr, E6 increased significantly. For compounds with 2, 3, and 4 phr zinc oxide, E6 had a tendency to decrease, but didn't decrease a lot.
Apr 05, 2017· • Most of the non black fillers such as china clay, mica powder, whiting (calcium carbonate), Lithopone, Blanc Fixe (barium sulphate) may be used in latex compounds. • Carbon black does not reinforce latex in the manner that it does dry rubber, and is used only in small amounts in latex for color, as are various other dyes and pigments.
This is also true for oxide–hydroxides where only heterogenite (40–60% Co), a weathering product of Co arsenides has been recognized in residual soils above ultramaﬁc rocks. Asbolane (also spelled asbolite) (b3% Co) is a mineral of the large group of hydrated Mn oxides (Table 05.01).

Sep 15, 2019· Zinc oxide is a naturally occurring compound, however, because of the commercial demand, much of the substance is now synthetically produced. It has a powdery consistency and is found in materials such as glass, paint, ceramics and batteries, among others.
Use of nano zinc oxide in natural rubber 4.1 Introduction 4.2 Experimental 4.3 Results and discussion 4.4 Conclusions 4.5 References 4.1 Introduction Natural rubber (NR) is a high molecular weight polymer of isoprene (2-methyl-1,3-butadiene). It is the oldest known rubber and the most versatile one for fabrication of rubber products.
Lithopone is an organically coated white pigment based on a co-precipitated zinc sulfide/barium sulfate. Our Product have below typical preoperties: low binder requirement, excellent dispersibility,neutral hue, low abrasiveness,thanks to low Mohs hardness.
GENERAL DESCRIPTION: Lithopone is a white pigment composed of a mixture of barium sulfate (28 - 30%) and zinc sulfide (68 - 70%) with trace amounts of zinc oxide. It is produced by precipitation through filtering, heating and quenching works.

Zinc oxide ZnO, the most widely used zinc compound and is used in the vulcanization of rubber, as well as in ceramics, paints, animal feed and pharmaceuticals, and many other products and processes. A special grade of zinc oxide has long been used in photocopiers. The oxide is also used in varistors (that provide protection against over-voltages).
The effect of Zinc Oxide level and blend ratio on tensile strength, modulus, elongation at break, hardness, abrasion resistance, compression set, and swelling behaviour of the vulcanizates were investigated. Results obtained show that the use of lower or higher than recommended level of Zinc Oxide in rubber
