How to improve the scratch resistance and wear resistance of plastics? 1.Choose the appropriate matrix resin 2. Use fillers with good wear resistance 3. Add appropriate wear-resistant additives

During blown film production, the adverse reactions of raw materials are summarized in the table below for reference.

The main technical parameters that should be paid attention to when selecting twin screw extruders. 1. Twin screw large diameter D, 2. Screw length-diameter ratio L/D, 3. Gearbox torque level T/A3, 4. Twin screw maximum rpm.

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.

Chinese Mid-Autumn Festival and National Holiday is coming soon, so our company is scheduled to have a holiday on Sep 29th and start work on Oct 6th.

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.

How to select screw parameters for different raw materials? (1) PC (Polycarbonate) (2) PMMA (Organic Glass) (3) PA (Nylon) (4) PET (polyethylene terephthalate) (5) PVC (polyvinyl chloride).

The extrusion machines in the domestic plastic industry are roughly divided into two categories: single screw extruder and twin screw extruder. Because these two types of equipment have their own characteristics, they are widely used in the plastic industry.
