Common eight functional modified engineering plastics.

1, wear-resistant modified engineering plastics

Wear-resistant modified engineering plastics can provide a lower coefficient of friction to reduce the wear rate. For example, the lid of a blood glucose meter can increase its back-and-forth service life when used with a wear-resistant material. At the same time, wear-resistant modified engineering plastics are also used in color matching products, even between different materials. In disposable products such as needles and blades also benefit from the lubricating effect of the material. In addition, other applications for wear resistant materials include catheters, cannulas, transmissions, and vacuum tubes. Other effects include reduced noise due to the movement of smooth parts, improved processing and production of plastics and extrusion molding efficiency.

Polyformaldehyde wear-resistant, but also creep resistance, chemical resistance, hardness, polysilicon wear-resistant polyformaldehyde products used in automobiles, electronic appliances and household appliances.

2, conductive modified engineering plastics

When the thermoplastic material adds a conductive component, it has a permanent electrostatic dissipation (ESD) and prevents electrostatic accumulation to provide protection. Conductive thermoplastics allow the release of electrostatic continuity rather than rapid accumulation and discharge. Static electricity can damage sensitive electronic components and can cause an explosion in a flammable environment. Accumulated static electricity can block the transmission of the material and interrupt the mechanical transmission. Conductive thermoplastic materials can be widely used in color matching products, and some conductive materials are transparent. Its use mainly includes, ECG sensors, pipettes, electrical protection devices and new medical delivery devices, such as inhalation products, including PMDI spacers.

3, spray-free modified engineering plastics

Spray-free plastic is a special pearl powder or metal pigment added to a specific resin. It is modified through the use of special compatible technologies. Direct injection molding can achieve various pearlescent, colorful or metallic appearance effects, and successfully solve special colors. Effects For many years in the injection molding products, there are difficult problems in the welding lines or flow marks, which meet the market trend of colorful texture, low consumption, high efficiency, and environmental protection and energy saving. Through the provision of personalized customized appearance color design, so that consumers get a good visual experience and safety and environmental protection.

Compared to traditional spray-painted plastics, spray-free plastics can be molded at one time, and aesthetic plastics with beautiful appearance can be obtained without painting. It has the characteristics of greener, more environmentally friendly, lower cost, higher design freedom and fewer process problems.

4, carbon fiber modified engineering plastics

Carbon fiber-based modified engineering plastics are mainly reinforced. They are composite materials formed by using carbon fiber or carbon fiber fabric as reinforcement and PA/PC/ABS/PBT/PPO as matrix. Mainly used in automotive manufacturing, electrical and electronic appliances, household appliances, sports equipment and other fields requiring high strength, high modulus, low specific gravity, anti-static, friction and other areas, including: automotive features, printers, detectors, electronic trays, Textile machine thread shuttle and so on.

Magnetic plastics are widely used in many fields such as electronics, electrical, instrumentation, communications, culture, education, health care and daily life. Their output and demand are constantly increasing, and they have great potential for development.

8, thermal conductivity of modified engineering plastics

Thermal conductive plastic is the use of thermally conductive filler (including particles, fibers, plies, etc.) to uniformly fill the polymer matrix material to improve its thermal conductivity. The thermal conductivity is mainly measured by the thermal conductivity (unit: W/(mk)). At present, the application of thermally conductive plastics in the LED field is the most extensive. In addition, heat-conducting plastics are also used in pipes, heat exchangers, automobiles, heating/cooling/refrigeration and the like.
