Introduction of Modified Plastics

Modified plastics, also known as engineered plastics, are a diverse group of materials derived from common or engineering plastics. Through various modification techniques, such as filling, blending, and reinforcement, the properties of these plastics are enhanced to meet specific performance requirements. Unlike their unmodified counterparts, modified plastics offer superior characteristics in areas such as flame retardancy, strength, impact resistance, and ductility.

Common Types of Modified Plastics

1. Nylon with Glass Fiber:This combination enhances the impact strength and rigidity of nylon, making it suitable for applications requiring high mechanical performance.
2. Nylon with Carbon Fiber:Carbon fiber reinforcement significantly improves the tensile strength, stiffness, and dimensional stability of nylon, making it ideal for demanding applications in aerospace and automotive industries.

Basic Modification Techniques

• Reinforcement:Incorporating reinforcing agents like glass or carbon fibers into the plastic matrix enhances its strength, stiffness, and dimensional stability.
• Filling:Adding fillers like minerals or inorganic particles modifies properties such as shrinkage rate, density, and cost-effectiveness.
• Blending:Combining different polymers with compatible additives improves ductility, impact resistance, and processing characteristics.
• Flame Retardancy:Adding flame retardants, such as halogenated compounds or phosphorus-based additives, enhances the plastic’s ability to resist ignition and self-extinguish.
• Low-Temperature Resistance:Incorporating low-temperature additives improves the plastic’s ductility and strength at low temperatures, expanding its application range in cold environments.

Applications of Modified Plastics

Modified plastics are widely employed in diverse industries due to their tailored properties:

• Automobilový průmysl:Parts like bumpers, fenders, and interior components benefit from the strength and impact resistance of modified plastics.
• Electrical and Electronic:Modified plastics with flame retardancy and high dielectric strength are used in electrical insulation and circuit boards.
• Konstrukce:Reinforced plastics provide structural integrity and durability for building materials, pipes, and windows.
• Spotřební zboží:Appliances, sporting goods, and toys often utilize modified plastics for their lightweight, impact-resistant, and aesthetic qualities.
