Composition and classification of engineering plastics The main component of plastics is resin, accounting for 40%~100% of the total amount of plastics. It can be applied to small household appliances such as washing machine compressor cover, vacuum cleaner case, coffee appliance, hair styling device, massager, microwave oven ware, etc. The modified polyphenylene oxide is also used for TV components, connectors of telex terminal equipment, etc. Engineering plastics refer to a class of high-performance polymer materials that can be used as structural materials, withstand mechanical stress in a wide temperature range, and are used in a more demanding chemical and physical environment- It refers to engineering plastics that can withstand certain external forces, have good mechanical properties and dimensional stability, and can maintain its excellent performance at high and low temperatures, and can be used as plastics for engineering structures. The adhesive types listed below have been found to be effective for Ryton PPS. Field investigation shows that most bimetallic cylinders are durable by about 3 to 1 nitriding cylinders. Although they are more expensive, bimetallic gas cylinders are recommended for this reason.

Bimetallic gas cylinders can be used in two ways. In one scheme, the sleeves are respectively generated and then put into the prebored barrel for reduction. This method allows working pressure. Polybutylene terephthalate (PBT) is widely used in electronic, electrical and automotive industries. Because of the high insulation and temperature resistance of engineering plastics, they can be used as the return transformer of TV, automobile distributor and ignition coil, office equipment shell and base, various automobile exterior parts, air conditioner fan, electronic stove base, and office equipment shell. 5. Polyphenylene oxide (PPO) PPO resin has excellent physical and mechanical properties, heat resistance and electrical insulation, low moisture absorption, high strength, good dimensional stability, and creep resistance under high temperature is excellent among all thermoplastic engineering plastics. We also suggest that you contact the adhesive manufacturer and ask them to recommend some heating cylinders of the adhesive injection molding machine that can effectively bond engineering plastics. The inner diameter of the cylinders is nitrided or other metal gaskets are added.

Engineering plastics for nitriding gas cylinders are made of special steel with high content and chromium aluminum and molybdenum. A downforce of approximately 150 pounds (68 kg) is required for approximately 40 seconds. The filler and reinforcement used in the engineering plastics mixture are abrasive, so we suggest that the end of the column must be made of hardened steel with Rockwell hardness C-60 or higher. High strength, high mechanical modulus, low latency, strong wear resistance and fatigue resistance. Good chemical resistance, electrical resistance, fire resistance, weather resistance and dimensional stability. Five commonly used engineering plastics -- PA, PC, POM, PBT, PPO1. Polyamide (PA) PA has won people's attention because of its unique low specific gravity, high tensile strength, wear resistance, good self-lubricating property, excellent impact toughness, and both rigid and flexible properties. 2. Polycarbonate (PC) PC not only has the strength similar to that of non-ferrous metals, but also has ductility and strong toughness. Its impact strength is extremely high, and it cannot be damaged when struck with a hammer, It can withstand the explosion of TV screen.
