What Are The Transparent Plastics

August 10, 2024

What are the transparent plastics? What are the differences between different transparent plastic applications?

The common ones are polymethyl methacrylate (PMMA), Polystyrene (GPPS), polycarbonate (PC), styrene-acrylonitrile (AS), styrene-methyl methacrylate copolymer (MS), and other special specifications such as PA12, COC, PPSU and PEI.

Below is a comparison of the performance differences between the major transparent plastics.

PMMA

PMMA has the best optical properties, 93% light transmission, better strength and abrasion resistance, scratch resistance, good heat resistance, excellent chemical resistance, small water absorption, also known as acrylic, plexiglass.

Transparent PS together with PMMA and PC is known as the three major transparent plastics, transparent PS is called GPPS, light transmittance 90%, lighter weight, water stability, rigidity with the addition of inorganic minerals. The following picture shows the application of PS organizer.

Polycarbonate PC comprehensive performance is excellent, is the more ideal choice, light transmittance 88-91%, high impact resistance, can be used for shields, small bulletproof adhesive, more in packaging, shells, lampshade applications.

Containing 20%-30% of acrylonitrile monomer, the rest of styrene monomer and its copolymerization, heat resistance and gloss is better, more used in cosmetic bottles, lighters those.

Composed of 70% ethylene and 30% methyl methacrylate copolymer, light transmittance 91-92%, chemical resistance and abrasion resistance good better than PMMA. application reference PMMA.

In addition to the above five transparent plastics, what other transparent plastics?

Transparent nylon: PA11, PA12, some PPA, 9T resin.

The most used is PA12, which is mainly used in pipes, glasses, lenses and so on. The following chart.

People buy resin eyeglasses, especially say TR90 or TR material is this. Imported material prices close to 200/KG, a kilogram of material can be processed 50 pairs of frames, sell 100 dollars a pair to you but not too much .

COC (cyclic olefin copolymer) materials have some of the following characteristics and applications:

①. High transmittance: has a similar transmittance to glass. ②. Low water absorption, dimensional stability, excellent chemical resistance, good strength and toughness.

Applications: Optical field: such as lenses, lenses, optical films, etc.

If the above PA12 for the lens frame material world crouching dragon, that COC is absolutely for the phoenix chick, the price is close, COC products can be even less cheap, a few grams of the lens sells 200 but not too much, and optical lenses, it must be a very expensive process .

Polysulfone class: PPSU, PSU, PES, etc.

Such as PPSU this material, the highest temperature 180, transparent material inside the bearer, but also food grade, chemical properties and particularly stable, good mechanical properties, hardband toughness, size and stability.

For well-off families, buy PPSU plastic to do the bottle, the best but, imported material PPSU prices up to 200/KG, than the glasses profit is still a little thin, the bottle sells 150 a, but not too much it .

PEI(Polyetherimide)

PEI is also amber transparent material, with the above polysulfone material has similar properties, in addition to food grade, PEI is more absolute excellent electrical properties, inherently flame retardant, fiber optic connectors like to use it, PEI because of its excellent performance, is widely used in aerospace, automotive, electrical and electronic appliances, medical equipment and other fields. Imported PEI price is also as high as 200/KG. plastic gold is that he said, not only yellow, PEI really expensive .

This article introduces nine categories of common transparent plastics, including PMMA, PS, PC, AS, MS, transparent nylon, COC, polysulfone, PEI, etc., and lists some of the application areas.
