Since the 1980s, PET has made breakthrough progress as an engineering plastic, and has continuously developed nucleating agents and crystallization accelerators. Currently, PET and PBT are used together 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: 26% of electrical and electronics, 22% of automobiles, 19% of machinery, 10% of appliances, 10% of consumer goods, and 13% of other products.
5 major application areas:
1, film sheet aspect
All kinds of foods, medicines, non-toxic aseptic packaging materials; textiles, precision instruments, high-grade packaging materials for electrical components; audio tapes, video tapes, motion picture films, computer floppy disks, substrates for metal coatings and photographic films, etc.; electrical insulation Materials, Capacitor films, Flexible printed circuit boards, Membrane switches, etc. 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 housings, capacitor housings, transformer housings, television accessories, tuners, switches, timer housings, automatic fuses, motor brackets and relays, etc.
4, auto parts
Such as switchboard enclosures, fire coils, various valves, exhaust components, distributor caps, meter housings, small motor housings, etc. PET's excellent coating properties, surface gloss and rigidity can also be used to manufacture automotive exterior parts. .
5, machinery and equipment
Manufacturing of gears, cams, pump housings, pulleys, motor frames and watch parts, microwave oven baking pans, various ceilings, outdoor billboards and models etc.
PET plastic molding can be injection molding, extrusion, blow molding, coating, bonding, machining, electroplating, vacuum metallization, 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 increasing and toughening modification before producing finished products.
PET (PETG) exclusive thickening and toughening agent
According to the principle of toughening and the processing temperature, the PET viscosifying and toughening agent and the PETG viscosifying and toughening agent can be used to increase the viscosity and toughness of raw materials and back materials without affecting the transparency (and also increase the transparency). For degree, +73 degrees), the viscosity can be increased to 20%, and the toughness can be greatly increased by 2-3 times. With the return material, the discharge material reaches the level of new material, and the product passes the US FDA.
Features and features:
For PET (PETG) sheet, chemical fiber, packaging tape, drawing and other materials.
The addition amount is small (0.2-0.6%), the cost is very 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 it with the raw material or the back material in the mixer for 20min, and stir it evenly with plastic to inject or extrude it. It is recommended to use 25 to 50K material for trial use. (The two must be baked and used. Add toughening agent after baking and stir and reprocess. To ensure product quality, please do not share it with other chemicals so as not to affect its effectiveness.)
Storage: When stored, should be placed in a cool place and kept dry, in addition to use, should not be directly exposed to sunlight. Packing: 25Kg / package model: PET toughening agent ZRO2.5.106 model: PETG toughening agent ZRO2.5.127
