Polybutanediol terephthalate (PBT) has excellent comprehensive properties, such as high crystallinity, rapid prototyping, weather resistance, low friction coefficient, high thermal deformation temperature, good electrical properties, excellent mechanical properties, fatigue resistance, can be ultrasonic welding. However, its notched impact strength is low, forming shrinkage rate is large, hydrolys...

Modification principle Modified plastics refer to plastics that are processed and modified on the basis of general plastics and engineering plastics through filling, blending, strengthening and other methods to improve the properties of flame retardant, strength, impact resistance, toughness and other aspects. The modification involves the additive of the plastic, the dispersion state of the filli...

Polyethylene terephthalate (PET) belongs to the polyester family. It is semi-crystalline when stable. It is recyclable and is resistant to impact, moisture, alcohol and solvents. It is one of the plastics that is an important part of everyday life. The polymer is used in the packaging, fabric and textile industries. It is also used in films to mold parts for automobiles, electronics and more. What...

Long Glass Fiber Reinforced Polypropylene (LGFPP) plastics are modified polypropylene composites containing glass fibers with a length of 10 to 25 mm, which are injection molded to form a three-dimensional structure, abbreviated as LGFPP. LGFPP is increasingly being used in automotive applications due to its excellent overall performance. Features and Benefits of Long Glass Fiber Reinforced Polypr...

Poly (butylene terephthalate) (PBT) is an excellent engineering material with excellent toughness, fatigue resistance, good heat resistance, good weather resistance, good electrical properties and low water absorption. Modified PBT material is to enhance its flame retardant modification, so as to improve its heat resistance, flame retardant, dimensional stability and modulus, used in automotive, e...

Glass fiber is a very common material in the chemical industry, often used in the production of reinforced plastics or reinforced rubber. Due to Glass Fiber has high temperature resistance, flame retardant, corrosion resistance, heat insulation, high tensile strength, good insulation characteristics, raw materials after adding glass fiber can significantly improve the heat resistance and mechanica...

1. Production Workshop The layout of the production workshop should consider two main aspects: meeting production requirements and optimizing layout based on production flow, while ensuring flexible energy use under specific production conditions. (1) Power Supply: Ensure a stable power supply with a moderate buffer to avoid excessive energy waste from unused capacity. (2) Efficient Cooling Water ...

Injection Mold 1. If the mold cavity is poorly machined, with defects such as scratches, micro-pores, wear, or rough surfaces, it will affect the gloss of the plastic part. To address this, ensure precise machining of the mold to achieve a lower surface roughness for the cavity; if necessary, polish and chrome-plate the cavity. 2. If the cavity surface has oil stains, watermarks, or excessive mold...
