Acrylic has always been the darling of the logo design industry because of its good light transmission, bright color and full touch, and it has always been the darling of the logo design. Light boxes and luminous characters are indispensable. Many exquisite designs have a more radiant glow with acrylic accents. Good acrylic is expensive, so there is a "recycled acrylic". How do you distinguish between "pure new acrylic sheet" and "recycled acrylic sheet"?

"Acrylic" English Acrylics transliteration, it is a generic term for acrylic and methacrylic chemicals, commonly known as "specially treated plexiglass." In the plastics field, acrylic refers to polymethyl methacrylate, or PMMA, which is a thermoplastic engineering plastic with excellent overall properties. Excellent optical properties (transparency is 92%); high surface gloss, bright color, fullness, smooth and flat, good hardness; chemical resistance; stable and not easy to deform; complete product range, colorful colors and various Different surface effects; stable physical properties (easy to form, strong plasticity); weather resistance, strong UV resistance, not easy to oxidize (high resistance to high and low temperature deformation, high temperature resistance 70 degrees, low temperature 50 degrees); easy to clean, maintain; outdoor 5 It will not fade, lose light, or open in -8 years. Outstanding impact resistance, suitable for installation in a relatively safe installation. It is light in weight and requires low load on the building body and the support. In the application industry, its materials generally appear in the form of granules, plates, pipes and the like. Applications include: aerospace industry, highways, civil industry, advertising industry, sanitary industry, and other forms of advertising.

Simple distinction and identification method of pure new material acrylic plate and recycled plate

Differentiating method:

1. Pure new material transparent acrylic board:

A: The light transmittance is greater than 92%, and the cross section is transparent and colorless.

B: Excellent UV resistance, no fading, loss of light, yellowing, cracking in outdoor 5-8 years

C: high surface hardness, comparable to aluminum and brass

D: excellent resistance to cracking and chemical resistance

E: High quality protective film that provides adequate protection

2. Recycled material recycled sheet transparent acrylic board:

A: light transmittance is less than 86%, yellowing at the cross section

B: The UV resistance is very poor. It will yellow at most for half a year, and cracks easily under sunlight.

C: low surface hardness, easy to scratch

D: easy to crack

E: The quality of the protective film is inferior and it is easy to deteriorate.

Identification method:

1. Return to the new material recycling board:

A: The appearance of the recycled plate is yellowed.

B: The surface is easily scratched, and the cutting is irritating.

C: When thermoforming is heated, bubble deformation is likely to occur.

D: sensitive to paints and inks, prone to silver streaks or cracks.

E: When burning, the foam emits black smoke and has a pungent odor.

2, pure new material acrylic plate:

A: The appearance of the recycled board is pure, especially from the cross section.

B: Excellent surface hardness and scratch resistance, and the cut is non-irritating.

C: Bubbles and deformation are less likely to occur during thermoforming heating.

D: It is stable to paint and ink.

E: When burning, no blistering, no black smoke, no irritating odor.
