Himei ABS PA 717C abs гранулы сырья высокая ударопрочность и термостойкость пластик

chemical property With the adjustment of the proportion of the three components, the physical properties of the resin will have
certain changes: 1,3-butadiene provides low temperature ductility and impact resistance for ABS resin, but too much butadiene will
reduce the hardness, luster and fluidity of the resin; Acrylonitrile provides ABS resin with hardness, heat resistance, acid,
alkali and salt resistance and other chemical corrosion properties; Styrene provides ABS resin with hardness, processing fluidity
and product surface finish. performance 1. General performance The appearance of ABS engineering plastics is opaque ivory granular
material, and its products can be painted into various colors with high gloss. ABS has a relative density of about 1.05 and low
water absorption. ABS has good adhesion with other materials and is easy to be printed, coated and plated. The oxygen index of ABS
is 18~20, which is a flammable polymer. The flame is yellow, with black smoke and special cinnamon flavor. 2. Mechanical
properties ABS has excellent mechanical properties, excellent impact strength, and can be used at extremely low temperatures: ABS
has excellent wear resistance, good dimensional stability, and oil resistance, and can be used for bearings under medium load and
speed. The creep resistance of ABS is larger than that of PSF and PC, but smaller than that of PA and POM. The bending strength
and compressive strength of ABS are the worst among plastics. The mechanical properties of ABS are greatly affected by
temperature. 3. Thermal properties The thermal deformation temperature of ABS is 93~118 ℃, and the product can be increased by
about 10 ℃ after annealing. ABS can still show a little toughness at - 40 ℃ and can be used in the temperature range of - 40~100
℃. 4. Electrical performance ABS has good electrical insulation and is almost independent of temperature, humidity and frequency.
It can be used in most environments. 5. Environmental performance ABS is not affected by water, inorganic salts, alkalis and many
kinds of acids, but it is soluble in ketones, aldehydes and chlorinated hydrocarbons, and will cause stress cracking due to
corrosion by glacial acetic acid, vegetable oil, etc. ABS has poor weather resistance and is easy to degrade under the action of
ultraviolet light; After half a year outdoors, the impact strength decreases by half. [1] Application field editing and
broadcasting The largest application fields of ABS resin are automobile, electronics, building materials and DIY manufacturing.
The use in the automobile field includes many parts, such as automobile instrument panel, exterior body panel, interior trim
panel, steering wheel, soundproof panel, door lock, bumper, ventilation pipe, etc. In electrical appliances, it is widely used in
refrigerators, televisions, washing machines, air conditioners, computers, copiers and other electronic appliances. In terms of
building materials, ABS pipes, ABS sanitary ware and ABS decorative plates are widely used in the building materials industry.
DIY, aircraft model wing, etc. In addition, ABS is also widely used in packaging, furniture, sports and entertainment products,
machinery and instrument industries. The important goals of automobile interior decoration include beauty, low smell, mechanical
performance, heat resistance, weather resistance, etc. Automotive materials can meet the use requirements of various interior
components and meet the following conditions: 1. Good liquidity 2. Excellent impact resistance 3. Easy processing and forming 4.
Easy to stain and spray 5. Low odor 6. Good corrosion resistance 7. Matte effect 3d printing field Abs engineering plastic is one
of the main materials for 3D printing. The reason why it can become a consumable for 3D printing is determined by its
characteristics. Abs plastic has the characteristics of heat resistance, impact resistance, low temperature resistance, chemical
resistance, excellent electrical performance, and stable product size. ABS application 1. Interior and exterior decoration of
vehicle: instrument panel, trim pillar, instrument front cover, grille, interior and exterior decoration 2. Business equipment
shell and built-in parts: notebook/desktop computer, copier, printer, plotter, display 3. Telecom, mobile phone shell, accessories
and smart card (SIM card): 4. Electrical products, electronic product housing, meter cover and housing, household switch, plug and
socket, cable conduit 5. Internal and external parts of household appliances, such as washing machine, hair dryer, microwave oven
Process conditions of PC/ABS injection mold: Drying treatment: drying treatment before processing is necessary. The humidity
should be less than 0.04%, and the recommended drying condition is 90~110C, 2~4 hours. Melting temperature: 230~300C. Mold
temperature: 50~100C. Injection pressure: depends on the plastic part. Injection speed: as high as possible.
