Ethylene Vinyl Acetate (EVA) is a thermoplastic elastomer formed by copolymerizing ethylene and vinyl acetate (VAc). Its properties vary with VAc content—lower content results in plastic-like characteristics, while higher content brings more rubber-like elasticity. EVA is widely used in injection molding, extrusion, and foam applications such as shoe soles, cable insulation, and packaging films. It improves flexibility, toughness, and compatibility when blended with PE or PP and can be modified for enhanced wear and tear resistance.

This article explains how to choose suitable carrier resins for color masterbatches in TPE (thermoplastic elastomer) pelletizing based on application scenarios. It emphasizes key selection criteria such as compatibility, processing temperature, performance impact, and cost-efficiency. Specific carriers like LDPE, PP, PS, EVA, and SEBS are recommended for different TPE uses—ranging from toys and automotive parts to medical tubing and food-grade products. It also highlights considerations for pigment-carrier matching, masterbatch concentration, and processing optimization.

▪ 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.

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.
