COC日本大坂天然气OKP4HT朔州PCOptical lighting: the right and left eyepiece for making large lampshade, protective glass, optical instrument and so on. It can also be widely used for transparent materials on aircraft.
Electronics: polycarbonate is excellent E (120 DEG C) level of insulation materials, insulation used in the manufacture of battery shell connectors, coil frame, pipe, insulation casing, telephone shell and parts, lamp etc.. It can also be used for making parts with high dimensional accuracy, such as CD-ROM, telephone, electronic computer, video recorder, telephone exchanger, signal relay and other communication devices. Polycarbonate is also widely used as capacitors, insulated leather bags, tapes, color video tapes and so on.
Machinery and equipment: it is used to manufacture various gears, rack, worm gear, worm, bearing, cam, bolt, lever, crankshaft, ratchet wheel, and also can be used for some mechanical parts such as shield, cover and frame.
Medical devices: cups, cylinders, bottles and dental devices, medicine containers and surgical instruments that can be used for medical purposes. They can even be used as artificial organs such as artificial kidney and artificial lung.
Other aspects: building used for double wall hollow steel plate, glass greenhouse, etc.; used as a textile bobbin, textile machine bearings in textile industry; daily aspects for bottles, tableware, toys and models.
PET 1, smell first, PET tastes different from general plastics, burn with lighter, and then smell a very fragrant and comfortable taste (smell a bottle to smell). If PET contains other ingredients, the taste will be very pungent. There is no use of SEBS in a bottle.
2. Look at the burned part, if it is too dark or the oil droplets are fast, most melting points are abnormal, which is often found in the PET film.
3, drawing, when burning on the cigarette lighter pull wire, see the long wire, then pull out the wire snapped, see the middle wire is not a breakpoint, small circle, volume more high melting point.
But generally, if it is a bottle, there should be no big problem. The key point is to distinguish whether or not PVC is contained, which is a fatal injury to PET. The first multi - sample, then the sunny place, PVC in the light blue in the sun. If there is a white crease in the fold. The above is the naked eye identification, the accuracy is limited, mainly to see the experience.
PETG has a glass like transparency and density close to the glass, good gloss, chemical corrosion resistance, impact resistance, and easy processing, to injection molding, injection stretch blow molding and extrusion blow molding. It can also produce unique shapes, appearances and special effects, such as bright colors, grind, marble texture, metallic luster and so on. And other polyester, elastic plastic or ABS can also be used for overlapping injection molding.
Products are perfume bottles and bottle, cosmetics bottles and bottle caps, lipstick tube, cosmetic box, deodorant packaging, bottle and cap liner powder etc.. PETG injection products are medical devices such as filters, Eustachian tube, pipe connection, pump, and dialysis equipment clamp. Household utensils such as cups, salad bowl, salt, Hu Jiaoguan etc., has excellent transparency, gloss, good toughness, processability and excellent color.
