Is polypropylene (PP) a food grade material?Not all polypropylene in polypropylene is food grade, and the polypropylene material involved in the food industry is food grade.

Polypropylene (PP) is a semi crystalline thermoplastic. Polypropylene has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid alkali corrosion.

When purchasing PVC boards, you should carefully observe the surface of the board to ensure flatness and no color difference. If there are slight cracks or scratches found on the PVC board

According to experts, PVC boards are the most commonly used in the entire building materials market. Depending on their hardness, they can be divided into two types: hard PVC boards and soft PVC boards.

The most prominent advantage of PVC flooring is mainly reflected in the absorption of vibrations by the knees, which can alleviate fatigue, provide comfortable foot texture, and a comfortable hanging decoration structure,

Titanium alloy refers to an alloy l made from titanium and other ls. It was developed in the 1950s and belongs to the category of structural ls. Among them, high-temperature titanium alloys and structural titanium alloys

The whitest feature of titanium dioxide is its high reflectivity and low visible light absorption. Titanium dioxide can reflect visible light back very effectively, making s look more white and bright. In addition,

Polyvinyl chloride, also known as PVC, is a polymer formed by the polymerization of vinyl chloride monomers with initiators such as peroxides and azo compounds, or under the action of light and heat,

Colored high titanium powder generally has good covering, stability, and light resistance, as well as good dyeing performance. Titanium dioxide, on the other hand, has excellent whiteness,

In our daily lives, PVC profiles can be seen everywhere. PVC profiles are rarely heard and feel unfamiliar, but when it comes to plastics, it is estimated that everyone is not very unfamiliar.

The production cost of PVC is mainly affected by the cost prices of coal, coke, electricity, calcium carbide, crude oil, ethylene, VCM, etc. In addition,

With the continuous development of modern industry, heat treatment technology has also made significant progress. In traditional heat treatment manufacturing,

From the perspective of industry development stage, PVC has entered a mature stage and has obvious buyer market characteristics. Therefore, the impact of downstream demand on commodity

The main component of wollastonite is CaSi3O9, which is fibrous and needle shaped. It has non-toxic, chemical corrosion resistance, good thermal stability and dimensional stability, glass and pearl luster,

Polyvinyl chloride, abbreviated as PVC, is an important organic synthetic material. It is a non-toxic and odorless white powder. High chemical stability and good plasticity. Excellent electrical insulation and generally does not burn.
