The most important quality of a duvet cover is its size. The correct duvet cover must be large enough to perfectly accommodate the duvet. The duvet cover should close tightly around the duvet without allowing much room for the duvet to move about within. Duvets are available in various conventional sizes depending on the type of bed for which they are intended, although their thickness might vary. In most cases, a duvet for a twin bed will measure around 68 inches wide × 86 inches long, while duvets for an extra-long twin should measure approximately 68 inches wide x 90 inches long. The dimensions of a duvet for a large bed can range from 78 inches long x 86 inches wide to 86 inches wide x 86 inches long. In general, the dimensions of duvets for the Queen and King-size mattresses are 90 inches wide x 90 inches long and 92 inches long × 104 inches wide, respectively.
In cosmetics, titanium dioxide’s properties enhance coloration and can help protect skin from damaging UVA and UVB rays.
- Titanium dioxide (TiO2) is a naturally occurring compound that has been widely used in various industries due to its unique properties. In the cosmetics industry, TiO2 is primarily used as a pigment and sunscreen agent. This article aims to provide a comprehensive guide to understanding the role of TiO2 in cosmetics, including its benefits, safety concerns, and regulations.
China’s TiO2 exports were booming in 2016. The continuously depreciating RMB and the increasing export scales of China’s manufacturers have strengthened this development throughout the year. As a fact, many of China’s producers exported their products with a lower price while achieving higher profit margins in the domestic market of TiO2. Tranalysis, a trade analysis provider, now reveals the top 10 Chinese TiO2 exporters of the year 2016 with the original data of China Customs.
- The precipitation of titanium dioxide can be achieved through several methods, including the sulfate process, the chloride process, and the hydrothermal process. Each method has its own advantages and disadvantages, and the choice of method depends on factors such as cost, availability of raw materials, and desired product characteristics.
Application:
1. Due to its rheological and optical properties, Lithopone offers technical and economic advantages wherever organic and inorganic resin systems need to be relatively highly pigmented for specific applications. Lithopone has therefore traditionally been used in putties, mastics, jointing and sealing compounds, primers, undercoats and marking paints. In powder coatings it is possible to replace TiO2 partially, very economically.
2. The low Mohs' hardness of Lithopone leads to low abrasiveness in comparison with TiO2.
3. Lithopone 30 % (= 30% zinc sulfide share) is proven to be of particular use as a TiO2 Substitute in thermoplastic masterbatches. Even at very high pigment loadings it disperses easily. A masterbatch containing 50 % TiO2 and 25 % Lithopone 30 % DS has the same hiding power as one containing 60 %TiO2. Cost savings are strongly related to the price ratio of Lithopone and TiO2 and the price of for example polyethylene or polypropylene.
4. The Lithopone batch has a much higher extrusion rate too. Furthermore the impact strength of many thermoplastics such as PP and ABS can be noticeably improved by using Lithopone as a TiO2 substitute. Generally spoken, Lithopone can be used at loadings up to 80 % by weight without causing polymer breakdown
Understanding Titanium Dioxide


One of the most common worries about titanium dioxide is that it could be a cancer-causing agent. The link between cancer and titanium dioxide traces back to a 1985 study where rats were exposed to high levels of titanium dioxide for two years, causing lung cancer. However, not all experts are convinced by this study.
