• Introduction To Glass Fiber Reinforced Thermoplastic Polyurethane (TPU) Modification

  Glass fiber reinforced thermoplastic polyurethane (GF-TPU) combines TPU’s elasticity with the rigidity of short glass fibers, resulting in improved modulus, tensile strength, tear resistance, heat resistance, and dimensional stability while retaining flexibility. Research shows that fiber type, length, and content significantly influence dispersion, anisotropy, wear performance, and impact resistance. Optimal designs balance stiffness and toughness for specific applications. GF-TPU composites—processible by injection molding, extrusion, and calendering—are already used in automotive and industrial parts, with aramid fiber variants offering alternative reinforcement options.

• Why Masterbatch Is Preferred Over Pigment Powder in Plastic Coloring

  Masterbatch is a pigment or dye concentrate encapsulated in a carrier resin, offering superior dispersion, stability, color consistency, safety, and cleanliness compared to direct pigment powder coloring in plastics. It ensures precise dosing, protects pigments from moisture and oxidation, and eliminates dust hazards. Made from pigments, carrier resin, dispersing agents, and optional additives, masterbatch comes in various resin types, grades, and applications, with specialized types providing the best compatibility. It can also deliver functional properties such as UV resistance or flame retardancy, maintains heat stability under normal processing, and is produced through methods like ink dispersion, flushing, or kneading using single- or twin-screw extruders.

• TPU And PVC Blending Modification (Part II)

  This article explores the blending modification of TPU and PVC to improve material performance and reduce costs. PVC/TPU blends show excellent oil resistance and enhanced flame retardancy, although higher TPU content can reduce solvent resistance. Adding chlorinated polyethylene (CPE) as a third component further improves tear strength, thermal stability, and processability while helping maintain TPU’s flexibility at low temperatures. The blending ratio significantly affects mechanical and shape memory properties, with ratios like TPU/PVC 90/10 offering optimal performance. Combining TPU, PVC, and copolyester (COP) can also produce melt-processable rubber that combines toughness, cost efficiency, and low-temperature flexibility.

• TPU And PVC Blending Modification (Part I)

  This article explores the blend modification of thermoplastic polyurethane (TPU) with polyvinyl chloride (PVC) to reduce costs and enhance performance. Blending TPU with PVC improves flame retardancy, hardness, processability, and weather resistance while lowering production expenses. Compatibility between TPU and PVC is driven by their similar polarity and molecular interactions, especially hydrogen bonding. Polyester-based TPU shows better compatibility than polyether-based TPU. Optimal TPU/PVC ratios balance tensile strength, tear strength, and hardness, with a 90/10 blend ratio often delivering the best mechanical properties. Overall, TPU/PVC blends combine cost-effectiveness with improved functional performance, making them suitable for applications like synthetic leather and flexible plastic products.

• What Is Masterbatch And Why Is It Used?

  Masterbatch is a concentrated blend of colorants, special effect pigments, and functional additives dispersed in a carrier resin. Supplied mainly as pellets, it’s added during plastic manufacturing to provide consistent color, unique finishes, and improved material properties. Masterbatch is widely used in processes like injection molding, extrusion, and blow molding across industries from packaging to automotive. It offers benefits over liquid colors and powders by ensuring cleaner production, precise dosing, and reduced waste. It can also be tailored for recycled polymers and combined with additives like UV stabilizers for enhanced performance. The production process involves blending, extrusion, cooling, and pelletizing to create ready-to-use masterbatch pellets.

• Effect of Blending SBS with PE And PS on Material Performance

  This article explains how blending SBS (styrene–butadiene–styrene) with PE (polyethylene) or PS (polystyrene) improves its properties. Adding PE enhances SBS’s abrasion resistance, hardness, weatherability, and tear strength, while maintaining good tensile strength and elongation. Blending with PS increases hardness and melt flow rate but may reduce tensile strength and elongation due to phase separation at higher PS content. Proper oil extension and using grafted compatibilizers can further improve processing and compatibility. These blending techniques help produce TPE/TPR materials and impact modifiers suitable for footwear, automotive parts, and plastic toughening applications.

• Introduction To EVA Plastic: Key Properties And Applications

  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.
