Industry prospects for PEEK materials
PEEK is a high-temperature-resistant, easy-to-process material, not only can be processed city all kinds of mechanical parts and high mechanical strength, is widely used in various industries, this material is both rigid and tough, and wear-resistant, good insulation, so many industries have adopted PEEK materials as a partial replacement for metal parts.

How do you determine if a product is bio-based?
Carbon-14 test is an international common method to distinguish biomass sources from petroleum fossil sources, according to American standard ASTM D6866, international standard ISO 16620, and European standard EN 16640, etc. The latest national standard "GB/T 39514-2020 Definition, Terminology and Labeling of Biobased Materials" also states that the test method for biobased carbon content is the carbon-14 method, which will be officially implemented from June 1, 2021. For architectural coatings, the newly released CSTM group standard "Bio-based Emulsion Interior Wall Coating" (T/CSTM 00447-2021) can be used as a reference for bio-based interior wall architectural coating products.

What are the factors affecting the gloss of water-based varnish?
The polymers selected in the film-forming resin in the formulation of water-based varnish have an important influence on the gloss of the finished product. In actual production, methyl methacrylate, butadiene, methyl acrylate, methyl acrylate, acrylic acid-β-hydroxyacrylic acid, acrylic acid, etc. Increase the amount of methyl methacrylate and butadiene, the coating hardness, good gloss, but brittle, folding resistance, poor resistance to dissolution.
