Who would have thought that recycled plastic(RA-30) sunglasses can give you fashion and function? More people are getting aware of the world’s natural issues. So, eyewear manufacturers have been innovating. They are turning their attention to building sunglasses good for the environment.

What is recycled plastic RA-30(Recycled Modified PMMA)?

The based material is recycled from clarity & transparent PMMA products, which were used in demo lens & display stands, etc.

PMMA is a crystal clarity engineering plastic with very excellent performance in optical features. However, it is not toughness enough.

For improving the toughness and impact-resistance in low temperature, we modify rPMMA by blended with acrylic butadiene-styrene copolymer.

It is developed for eyewear, especially appropriate for reading glassesoptical glasses and sunglasses.

But how do eyewear producers make recycled plastic sunglasses? What can you get from using a pair of eyewear from recycled plastic materials? Let us check out the things to know about recycled eyewear fashion.

Defining Recycled Plastic Sunglasses

Technology has offered eyeglass producers ways of making recycled sunglasses. What’s more special about it is that the users can wear eco-friendly eyewear. Each pair is from thrown plastic material turned into something beautiful and useful.

Recycled Plastic Sunglasses provide fashion and function. So, you can make yourself look good while protecting your eyes.

It helps them create optic and reading glasses and various styles of sunglasses. Since each pair is BPA-free, it is safe to use for all ages.

Where Are Recycled Plastic Sunglasses From?

PMMA or acrylic is a rigid plastic that is easy to mold. This material is an excellent alternative to less resilient glasses.

PMMA has a lot of beneficial properties. So, this material makes it ideal for various applications. Some producers use it in car windows, smartphone screens, to aquariums.

What makes acrylic suitable for sunglasses application? It’s because it offers high-resistance to sunlight and weathering. Recycled sunglasses offer unlimited coloring options as well. It makes your fashion more flexible.

How Recycled Plastic Eyewear Are Made?

Don’t you feel good knowing that you are using a recycled item? It may seem a little, but it means a lot for our community and planet. It takes effort, time, and technology to produce something new from the trash.

Recycled items start with collecting plastics as the primary material. Producers get it from recycling programs and collection points.

Then, they would start the recycling process, which we’re going to talk about next. So, let us look at the process of making recycled plastic sunglasses.

Injection Molding

The recycled plastic sunglasses go through injection molding after sorting fee usable recycled materials. Injection molding refers to the process of molding the desired shapes of frames.

Most of the time, this process requires a melt temperature of about 200 to 250 degrees Celsius. Then, the molding temperature is about 40 to 80 degrees Celsius. Controlling high temperatures is crucial to get the right shape.

Painting of the Recycled Plastic Sunglasses

So what happens after shaping the recycled plastic sunglasses? The producer will paint or put the pattern on the frame.

Water transfer and heat transfer are the two processes in doing it. These methods offer fast and accurate painting or designing of the frames.

Heat Transfer

Heat transfer is transferring a pattern design on the frames through high heat. First, the producer would print the design on a thin sheet of paper wax.

Then, they will put the pre-shaped sunglasses in a heat press. This machine uses a high temperature. It transfers the design from the sheet of paper wax to the frame.

With one push of the heat press, it can paint several frames at a time. This process provides results fast as a flash of lightning.

The heat transfer produces durable, and heat-resistant designs. It can create high-resolution designs with bright and bold colors as well.

Water Transfer

Water transfer is another way of designing a pattern on the frame. Some call it hydrographic, hydro dipping, or hydrographic printing.

This process can transfer a high-definition graphic pattern to the frame. Water transfer uses a water-soluble film. Then, it contains the printed patterns.

The film dissolves in the water, leaving ink on the surface. It looks like floating lilies. Then with one smooth deep, the frames will get painted with the design.

Assembly

After drying, it is time to assemble the other parts of the sunglasses. It includes the lenses, nose pads, and the temple.

Advantages Of Recycled Plastic Sunglasses

PMMA or acrylic offers various advantages. It exhibits qualities that can make tough and effective sunglasses. Let us discuss the benefits of recycled plastic sunglasses.

Benefit #1 – Ideal For Most Outdoor Use

This material can have a refractive index of 1.49, but what does it mean? It means that sunglasses from Recycled Modified PMMA offer high light transmittance.

With this feature, recycled plastic sunglasses are ideal for most outdoor use. You can wear them when doing errands and even playing other outdoor sports.

Benefit #2 – Impressive Toughness

RA-30(Recycled Modified PMMA) is a tough and lightweight material. It has less density compared to a glass and even polycarbonate material. You can get a scratch-resistant pair of sunglasses as well.

So, if you’re in doubt about wearing a pair of eco-friendly sunglasses, think twice. It gives purpose while making you look good. It’s like you’re wearing a regular pair of sunglasses. No one would ever notice that it is from recycled materials.

It won’t get moist when the weather is cold or hot. If you’re an outdoor enthusiast, you will appreciate this performance.

Benefit #4 – Chemical Resistance

Recycled plastic sunglasses made from RA-30(Recycled Modified PMMA) material offer high resistance to chemicals. It can withstand detergents, cleaners, and dilute inorganic acids.

So, you don’t have to worry if you get clumsy with your laundry detergent. But proper cleaning is still essential for any recycled eyewear.

Are Recycled Plastic Sunglasses For You?

The best way to know if recycled plastic sunglasses are for you is to test them out. But no one can even notice the difference between recycled to new sunglasses. The first one is an excellent option because you’re choosing it for a cause. Going green can help our nature.
