Price trendAccording to the monitoring of toodudu, the price of titanium dioxide has been reduced this week. At the beginning of the week, the domestic average price of titanium dioxide was 14,166.67 RMB/ton, and the average price at the weekend was 13,866.67 RMB/ton. During the week, prices fell by 2.12%.Analysis reviewBeginning in June, the titanium dioxide price market showed no signs of improvement, foreign trade remained weak, domestic titanium dioxide companies were under greater sales pressure, and the market continued to weaken. This week, the price of titanium dioxide has been lowered, and some manufacturers have lowered their prices in varying degrees. At present, the domestic ex-factory price of rutile titanium dioxide is 12,000-14,500 RMB/ton, and the ex-factory price of anatase titanium dioxide is 10,300- 11,800 RMB/ton, the price of chlorinated titanium dioxide is 15,500-20,000 RMB/ton. As far as the current international situation is concerned, the wait-and-see sentiment...

Q difference between polypropylene and polycarbonate

Polypropylene (PP) and Polycarbonate (PC) are both plastics with distinct properties and applications. PP is a type of thermoplastic polymer, widely known for its toughness, resistance to chemical solvents, bases, and acids, making it ideal for containers and packaging. It has a high melting point, which makes it suitable for items that need to be sterilized. On the other hand, PC is an amorphous thermoplastic, known for its high impact resistance, clarity, and ability to withstand high temperatures without deforming. It is often used in making bulletproof glass, eyewear lenses, and electronic components due to its clarity and strength. While both are valuable in the plastics industry, their differences in strength, clarity, and heat resistance define their unique applications.

Q will a vinyl decal stick to high density polyethylene

Vinyl decals generally struggle to adhere to High-Density Polyethylene (HDPE) surfaces due to the material’s low surface energy, making it non-porous and chemically resistant. Adhesives find it hard to form a strong bond with HDPE. However, it’s not impossible. Surface treatment methods such as flame treatment, corona treatment, or the application of a primer can increase the surface energy of HDPE, making it more receptive to adhesives. These treatments alter the surface at a molecular level, enhancing adhesion. For the best results, ensure the HDPE surface is clean and consider consulting with a specialist about the appropriate treatment method for your specific application before applying a vinyl decal.

Q how much polyester resin do i need

The amount of polyester stuffing needed depends on the project size and desired firmness. For small projects like toys or pillows, 1-2 pounds can suffice. Larger projects, such as comforters or upholstery, may require 5-10 pounds or more. Consider the item’s dimensions and how plush or firm you want it to be. A general guideline is to estimate the volume of your project in cubic inches (length x width x height) and compare this to the expansion rate of the polyester stuffing you’re using, typically noted on the packaging. It’s always better to have a little extra than not enough, as you can adjust the stuffing density to achieve your desired outcome.
