PETG vs acrylic which is more cost effective

Regardless of the physical properties of the material, only from the **, density, processability of the personal opinion that the current acrylic is high, the current PETG ordinary grade is about 23000, PMMA is about 24000, PETG density, PMMA in, the requirements for the mold PETG to low mold temperature, summer ice water is to pass, and the processing cycle of PETG is longer than PMMA, PETG drying is also very strict. This is just from the cost consideration, each material has his own market, has his advantages, to consider comprehensively. I'm the one who sells PETG, hehe.

It's hard to do.

1. PC has good scratch resistance, strong wear resistance, better heat resistance, and can be boiled.

2. The dimensional stability of the injection-molded PC lens is better, and the PC lens can be made into high-precision far-sighted and near-sighted lenses when the PC lens is injection molded, and the transparent lens is not easy to turn yellow.

There are a lot, 3, acrylic lenses ** cheap; The molding temperature is low, which makes it easier to process, especially for sheets.

The differences between PET plastic and acrylic are as follows:

First, the material composition is different.

PET plastic is also called polyethylene terephthalate, and the chemical formula is [CoC6H4Cooch2CH2O]N. Polyethylene terephthalate, referred to as PET, is a common resin in life prepared by the exchange of dimethyl terephthalate and ethylene glycol esterification or esterification of terephthalic acid and ethylene glycol, and then polycondensation reaction.

Acrylic, also known as PMMA or plexiglass, is derived from the English acrylic (acrylic plastic), the chemical name is polymethyl methacrylate, which is an important plastic polymer material developed earlier.

Second, the performance characteristics are different.

1. Performance characteristics of PET:

It has excellent physical and mechanical properties in a wide range of temperatures, with a long-term use temperature of up to 120, excellent electrical insulation, and even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are very good.

2. Acrylic performance characteristics:

It has crystal-like transparency, excellent weather resistance, high surface hardness and surface gloss, and good high-temperature performance, due to good processing performance, it can be both thermoformed and machined.

The wear resistance of acrylic sheet is close to that of aluminum, with good stability and resistance to a variety of chemicals. And it has good printability, sprayability, and flame resistance.

Third, the use is different.

Yuyuan 1, PET plastics are widely used, mainly used in: electronic appliances; It can be spun into polyester fibers, i.e. polyester; It can be made into film for substrates, insulating films, product packaging, etc. for audio recording, video recording, film film, etc.; It can be blown into various bottles, such as cola bottles, mineral water bottles, etc.; It can be used as electrical parts, bearings, gears, etc.

2. Acrylic is mainly used in: architecture, such as acrylic board, acrylic artificial marble, acrylic bathtub, etc.; It can be used as a latex paint and adhesive and other answering rocks.

Dear, you are a good sparrow, I am happy to answer for you, PETG plastic or tritan which is better than PET material Tritan material and PET, or Tritan material is better in this world. Because the tritan material is the safest of all plastic materials, it does not contain any bisphenol substances, and has the characteristics of high temperature resistance, and the cup sail of the tritan material can be put in 100 degrees of boiling water and will not release harmful substances. The PET material has good light transmittance, impact resistance and high temperature resistance, but the PET material will be released when it encounters high temperatures, which is not good for the human body and will affect the health of the human body.

Nowadays, consumers have paid more and more attention to environmental protection factors, so PET cabinet doors have also been recognized and loved by consumers. Then PET and acrylic.

What's the difference?

1. Different compositions: the former is composed of synthetic resin, and the latter is also called plexiglass, which belongs to polymer materials.

2. Different performance: the former has good electrical properties and temperature resistance up to 120 degrees, while the latter has a shiny, transparent surface and weather resistance.

Good. 3. The former is widely used and can be used in electronic appliances. The latter is mainly used in construction.

That's all for you about what the difference between PET and acrylic is.

1. Impact performance: PETG impact resistance is better than PMMA!

2. Flame retardant performance: PETG: V-2

pmma：hb

UL-94 standard).

3. Bisphenol A: PETG does not contain bisphenol A

Wait, you can do an impact test, and you can know if you break the sample by hand. PETG is very tough!!

The landlord's question is how to distinguish, you can choose to burn it with an open flame, the smelly is pmma, and the sweet is petg. You can choose to fold in half, the broken is PMMA, and the continuous folding is PETG. You can rub it on the surface with a hard object, PETG is easy to scratch, and PMMA is not easy to scratch.

That's probably it.

PET: Polyethylene terephthalate, English name Polyethylene Terephthalate (referred to as PET).

PET is used in large quantities as a fiber, while engineering plastic resins can be divided into two categories: non-engineering plastic grade and engineering plastic grade, non-engineering plastic grade is mainly used for bottles, films, sheets, bake-resistant food containers, etc.

It can be used in direct contact with food, but it cannot be heated at high temperatures.

Acrylic: PMMA plastic (plexiglass) (polymethyl methacrylate) English name: polymethyl methacrylate

Excellent transparency, high strength, certain heat and cold resistance, corrosion resistance, good insulation, comprehensive performance more than polystyrene, but brittle, easy to melt in organic solvents, such as light transmission materials, its surface hardness is slightly lower, easy to rub. It is suitable for making transparent insulating parts and parts of average strength.

The composition of PET is polyethylene terephthalate, but the properties of this material are milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. The long-term use temperature can reach 120 °C, but the corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are very good. （Boding insulation

Acrylic is a kind of plexiglass, the composition is polymethyl methacrylate, excellent transparency, high strength, certain heat and cold resistance, corrosion resistance, good insulation, but it is relatively easy to scratch.

PET, PET resin, and PET plastic are the same concept. PET is the abbreviation of Polyethylene Terephthalate, the chemical name is polyethylene terephthalate, and the chemical formula is CoC6H4Cooch2CH2O.

Polyethylene terephthalate is also commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol, which is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good friction resistance, low wear and high hardness, with the largest toughness among thermoplastics; The electrical insulation performance is good, and it is less affected by temperature, but the corona resistance is poor.

Non-toxic, weather-resistant, chemical-resistant, stable, hygroscopic, drying before molding is a must. Resistant to weak acids and organic solvents, but not resistant to hot water immersion and alkali.

PET is commonly used in the manufacture of mineral water bottles, carbonated beverage bottles, etc. When the temperature reaches 70, it is easy to deform and precipitate substances that are harmful to the human body. PET can also be used in a wide range of applications for various coil frames, transformers, televisions, tape recorder parts and housings, automotive lamp holders, lamp shades, in-hot lamp holders, relays, selenium rectifiers, etc.
