1. Understand PCTG PCTG is a kind of transparent plastic, a non-crystal synchronous polyester. The commonly used commonly used by PCTG is 1,4-cycloral methal alcohol (CHDM). , 4-cycloral alkanol. It is the product of three monomers: pta, ethylene glycol (Eg), and 1,4-cyclohate alkanol (CHDM). -The cycanol binary co -concentration monomer, which is more ethylene glycol clustering monomer than PCT. Therefore, the performance of PCTG is very different from PET and PCT. PCTG is a non -crystal -oriented polyester. As the CHDM in the convergent increases, the melting point decreases, the glass -based temperature rises, the crystallinity decreases, and a non -fixed polymer is formed. Generally, the content of CHDM in PCTG is 30%-40%.
Has good viscosity, transparency, color, chemical resistant agent, and anti -stress albinization. It can be fascinated or squeezed out. The viscosity is better than acrylic (acrylic). PCTG is a kind of amorphous synchronization. Its product is highly transparent and has excellent resistance to impact. It is particularly suitable for forming thick wall transparent products. Its processing and molding performance can be designed according to the designer's intention. The molding methods such as squeezing, injection, blowing plastic, and plastic suction can be widely used in markets such as plate materials, high -performance contraction membranes, bottles and alien materials, cosmetics packaging and other markets. At the same time, their secondary processing performance Machine processing and modification.
2. Application of PCTG in the cosmetic packaging industry PCTG has glass -like transparency and density close to glass, good gloss, chemical corrosion, impact resistance, and easy processing. It can inject molding, injection, and squeezing molding. It can also produce unique shapes, appearance and special effects, such as bright colors, frosted, marble texture, metal luster, etc. It can also use other polyester, elastic plastics or ABS for overlapping plastic molding.
The products include perfume bottle and bottle cap, cosmetics bottle, lipstick tube, cosmetic box, deodorant packaging, refreshing powder bottle and eyeliner. PETG injection molding products include medical devices such as filters, earmop tube, tube connectors, pumps, fixtures, and dialysis equipment. Household utensils such as cups, salad bowls, salt tanks, pepper cans, etc., have excellent transparency, gloss, good toughness, processing, and excellent coloring.
PCTG is a highly transparent co -polyester plastic raw material. It has high transparency, good toughness and impact strength, excellent low temperature toughness, high tear resistance and good processing performance, excellent chemical resistance. Traditional methods such as squeezing, injection molding, blowing plastic and plastic suction can be adopted for processing. Widely used in plate materials, high -performance contraction membranes, bottles, and alien market; can be used to produce toys, home utensils and medical supplies, etc.
