Since the 1980s, PET has made breakthrough progress as engineering plastics and has continuously developed nucleating agents and crystallization accelerators. PET and PBT are now used as thermoplastic polyesters and become one of the five engineering plastics (PA PC POM PBT PPO). ).
The current consumption of PET engineering plastics in several application areas is: electrical and electronic 26%, automotive 22%, mechanical 19%, appliance 10%, consumer goods 10%, and others 13%.
Application area:
1, film sheet
All kinds of foods, medicines, non-toxic aseptic packaging materials; high-grade packaging materials for textiles, precision instruments, and electrical components; substrates for audio tapes, video tapes, motion picture films, computer floppy disks, metal coatings, and photographic films; electrical insulation Materials, capacitor films, flexible printed circuit boards, membrane switches, and other electronic and mechanical fields.
2, the application of bottles
Its application has been developed from the initial carbonated beverage to the current beer bottle, edible oil bottle, condiment bottle, medicine bottle, cosmetic bottle and so on.
3, electronic appliances
Manufacture of connectors, coil bobbins, integrated circuit enclosures, capacitor enclosures, transformer enclosures, TV accessories, tuners, switches, timer enclosures, automatic fuses, motor brackets, and relays.
4, auto parts
Such as switchboard enclosures, ignition coils, various valves, exhaust components, distributor caps, meter housings, small motor housings, etc., can also use PET's excellent coating properties, surface gloss, and rigidity to make automotive exterior parts. .
5, machinery and equipment
Manufacture of gears, cams, pump housings, pulleys, motor frames and timepiece parts, can also be used as microwave oven baking trays, various ceilings, outdoor billboards and models.
PET plastic molding can be injection molding, extrusion, blow molding, coating, bonding, machining, electroplating, vacuum metallization, and printing.
When PET is used in plastic sheet, bottle, chemical fiber and other fields, due to its own chemical properties, it is necessary to perform viscosity-enhancing and toughening modification before producing the finished product.
PET (PETG) exclusive thickening and toughening agent
According to the principle of toughening and the processing temperature, it can be divided into PET viscosifying toughener and PETG viscosifying toughening agent. It has the effect of increasing viscosity and toughness for raw materials and back materials without affecting the transparency (and also increasing the transparency) and can solve (-40) For degree, +73 degrees), the viscosity can be increased to 20%, and the toughness can be greatly increased by 2-3 times. To make the feed and outlet materials reach the level of new materials, the products passed the FDA.
Features and features:
For PET (PETG) sheet, chemical fiber, packaging tape, drawing and other materials common.
The addition amount is small (0.2-0.6%), the cost is extremely low, and the effect is obvious.
Can greatly improve the plastic's viscosity and toughness, but also physical and chemical properties can also be improved.
How to use: Simply mix and stir with the raw material or the back material in the mixer for 20 minutes so that it can be injected or extruded after mixing with the plastic. It is recommended to use 25 to 50K trial. (Because both must be baked, add a toughening agent after baking to stir and reprocess. To ensure product quality, please do not share it with other chemicals so as not to affect its efficacy.)
Storage: When stored, should be placed in a cool place and kept dry, except for use, should not be directly exposed to sunlight.
