The blending toughening of polypropylene PP is widely used in various fields due to its significant effects, low industrial investment, and fast and easy implementation. Blending toughening modification refers to the use of other plastics, elastomers, and inorganic powders as modifiers to blend with PP to improve the toughness of PP plastics.

Edge sealing hot melt adhesive is a type of adhesive specifically used for pasting artificial boards. It is an environmentally friendly, solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, it transitions from a solid state to a molten state. After being coated on the surface of the artificial board substrate or edge sealing material, it cools down to a solid state, bonding the material to the substrate.

The granulation process is the production process of producing granular plastic from high polymer resin and various additives and additives, which are measured, clubbed, plasticized, and cut into particles.

Before processing and granulating, a complete set of granulation equipment is required, which is the TPE/TPR granulation production line. The basic components include mixing equipment, plasticizing equipment, cooling equipment, granulating equipment, and batch mixing equipment. Common TPE/TPR pelletizing production lines include "strand pelletizing", "underwater pelletizing" and "water ring pelletizing".

Special color masterbatch has significant advantages such as high concentration, good dispersion and cleanliness during product processing.

The current automotive sealing strip materials mainly include four types: PVC sealing strip, EPDM sealing strip, TPV sealing strip, and TPE sealing strip. Below, we will analyze the advantages and disadvantages of these four automotive sealing strip materials.

in order to meet the needs of different uses, chemical or physical methods are used to change some properties of plastic products to achieve the intended purpose, which is plastic modification.

The meshing type co-rotating parallel twin screw extruder has the advantages of high conveying efficiency, strong dispersion and mixing ability, good self-cleaning performance, uniform distribution of material residence time in the machine and good adaptability, and is widely used in blending modification between different plastics and between plastics and rubber.
