▪ Pre mixing - refers to the mixing of modified materials (base materials, auxiliary materials, additives) in the pre mixing machine before the polymer mixing host (such as twin screw, continuous mixer, Booth kneading machine, three screw, etc.), and basically operating below the melting point of the base resin; ▪ Mixing - refers to the use of measuring scales (including weight loss scales, weight gain scales, solid volume pumps, etc.) above the main material inlet of the mixing host to achieve "mixing" of multi flavored materials in a small discharge well (or hopper), and to achieve "mixing" in the host; The latter obviously completes wetting, dispersion, extrusion, and granulation above the melting point of the base material.

Plastic modification refers to the process of improving or improving the original properties of resins through physical, chemical, mechanical, and other means. Modified plastics are collectively referred to as "modified plastics".

TPE/TPR materials have recyclable properties, do not contain any potential toxic ingredients, have adjustable hardness, and support oil spraying, screen printing, and printing processing, making them a good choice to replace PVC materials!

Transparent nylon is a polymer material with excellent comprehensive properties. It not only has advantages such as high mechanical strength, good thermal stability, and excellent corrosion resistance, but also has advantages such as easy forming and processing, good dimensional stability, low linear expansion coefficient, high cost-effectiveness, excellent electrical insulation and aging resistance, non-toxic, odorless, and easy to form alloys with other amorphous or semi crystalline polyimide.

Five common problems and countermeasures in plastic granulation processing 1.Black spot 2.broken bar 3.Hollow 4.Venting 5.Bridging

How much do you know about hot melt adhesive? 1、 Composition of hot melt adhesive 2、 Characteristics of hot melt adhesive 3、 Types and applications of hot melt adhesives 4、 Main testing indicators of hot melt adhesive 5、 The main factors affecting the adhesion of hot melt adhesive 6、 Correct usage of hot melt adhesive

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.

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

The technical support of pvc pelletizing is operated by a pvc pelletizing machine. Its main working method is wet pelletizing. A certain amount of water or steam is used to make the basic fertilizer fully chemically react in the cylinder after the humidity is adjusted.
