[Imported stearic acid supply] PCV edge banding strip and auxiliary material stearic acid introduction

Furniture edge strips are used to protect, decorate and decorate the cross-sections of furniture panels. Beautifying material, it can make a piece of furniture show clear wood grain and colorful overall effect. The main function of the edge banding strip is to seal the section of the board to protect it from damage caused by the environment and unfavorable factors during use (mainly moisture) and to prevent the formaldehyde inside the board from volatilizing, while achieving a beautiful decorative effect.

The PVC edge banding strip is made of polyvinyl chloride as the main raw material, with added plasticizers, stabilizers, lubricants, dyes and other additives. A thermoplastic roll made by mixing and pressing together. Its surface has patterns and patterns such as wood grain, marble, cloth grain, etc. At the same time, the surface gloss is soft, with the realism and three-dimensionality of wood; it has a certain smoothness and decorativeness, and has certain heat resistance, chemical resistance, corrosion resistance, The surface has a certain hardness. The main function of the edge banding strip is to seal the section of the board to protect it from damage caused by the environment and unfavorable factors during use (mainly moisture), and to prevent the formaldehyde inside the board from volatilizing, while achieving a decorative effect.

PVC edge banding strip base material is composed of PVC resin, calcium carbonate powder and various auxiliary materials (stabilizer, DOP oil, ACR, stearic acid, carbon white powder , toner, anti-aging agent, etc.). The trimming effect of the edge banding strip is related to the proportion of base material ingredients.

Stearic acid as auxiliary material for PCV edge banding strip:

Stearic acid is a fatty acid that is widely found in nature. It is a white flake, bead or block solid at room temperature. It is composed of saturated fatty acids mainly C16 and C18. It is insoluble in water, slightly soluble in benzene and carbon disulfide, easily soluble in hot ethanol, and is non-toxic and tasteless.

Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat stabilizer with good lubricity and good light and heat stabilization. Stearic acid helps prevent “scorching” during processing. It is an effective heat stabilizer added during PVC film processing and can prevent discoloration of the finished film caused by exposure to sulfides. When used as an internal lubricant, the internal lubricant has a certain degree of compatibility with the polymer. After adding it, it can reduce the cohesion between polymer molecules and reduce its melt viscosity, thereby weakening the internal friction between polymers.
