Reasons and countermeasures for insufficient filling during TPE/TPR injection molding

　　Many people do not quite understand what is underfill? Simply put, underfill refers to the phenomenon of incomplete material flow end or a part of a mold cavity is not filled.

TPE/TPR injection molding products summary of problems

　　1. Flow marks or wavy lines appear on the surface of TPE/TPR injection molded products. 　　Causes. 　　(1) Insufficient pressure-holding. It can be solved by increasing the injection pressure, holding pressure, holding time, melt glue amount, etc.

The causes and solutions of lusterless and uneven color of TPE/TPR products

　　TPR/TPE and other injection molded products appear dull surface, or luster, color uneven. Troubled many people do TPE, light polishing mold, increase the back pressure; heavy reformulation, adjust the system! Here are a few reasons to analyze the insights. Only for the injection molding products program.

Flowability of TPE/TPR raw materials

　　Flowability is an important physical processing parameter of polymer materials, and TPE is no exception. For example, the melt index of a TPE material is 3.5g/10min (5kg, 190℃), which means that at a melt temperature of 190℃, a melt index tester with a pressure of 5kg, after 10 minutes of testing, a total of 3.5 Fluid volume. Obviously, the larger the MI value, the better the fluidity of TPE!

TPE/TPR soft plastic in different hardness of the overmolding application

　　TPE cover usually refers to the use of hard plastics and soft plastics of these two materials for cover glue bonding. Hard plastics are usually general engineering plastics (such as ABS, AS, GPPS, HIPS, PA, PC, PC/ABS, PE, PP, etc.), while soft plastics are most commonly TPE/TPR elastomers. TPE is usually referred to as SEBS type styrene thermoplastic elastomer modified material, and its unique advantage is that it has a wide range of adjustable hardness.

TPE/TPR thermoplastic elastomer viscosity is influenced by those factors

　　What conditions affect the viscosity of TPE thermoplastic elastomers? 　　1, the influence of temperature 　　Different TPE materials have different sensitivity to temperature, for example, when measuring the melting finger can be measured more than a few temperatures, if the melting finger is very different, it means that the TPE material viscosity is highly sensitive to temperature, suitable for extrusion materials.

The physical and chemical properties of TPEE

　　Thermoplastic polyester elastomer referred to as TPEE or COPE, is a class of linear block copolymers containing PBT (polybutylene terephthalate) polyester hard segment (crystalline phase) and aliphatic polyester or polyether (amorphous phase) soft segment. TPEE belongs to high-performance engineering grade elastomer, with high mechanical strength, good elasticity, impact resistance, creep resistance, cold resistance, bending fatigue resistance, oil resistance, chemical resistance and solvent erosion, etc., and has good processability, and can be filled, reinforced and alloyed modification, in automotive parts, hydraulic hoses, cables and wires, electronic and electrical appliances, industrial products, stationery, biological materials and other fields have been widely used. Solvent erosion and other advantages, has good processability, and can be filled, enhanced and alloyed modification, in automotive parts, hydraulic hoses, cables and wires, electronic appliances, industrial products, sports and cultural goods, biological materials and other fields have been widely used.
