The Best Material for Boat Windscreens

All boats, from speedboats to luxury yachts, endure a fair amount of abuse. Marine windshields are no exception. In addition to being exposed to intense UV rays, marine windshields need to withstand wind, water and salt spray.

 

That's why special plastics are needed to make marine windshields. The following plastics are tougher and safer than glass and are designed to withstand all the wear and tear that the high seas can inflict on them.

 

Cast Acrylic Sheet

As the name suggests, cast acrylic sheet is manufactured using a process that sees MMA (methyl methacrylate monomer) liquid poured into a mould, which is then submerged in warm water to trigger the polymerisation process and set the plastic. Cast acrylic sheet can be ordered in different thicknesses, colours and tints, depending on the unique needs of the client.

 

The Best Material for Boat Windscreens


Polycarbonate

250 times stronger than glass, polycarbonate offers excellent UV resistance, as well as durability against high impact force. This makes it ideal for manufacturing boat windscreens, as well as panels used for boat windows and skylights.

It’s often treated with scratch and UV-resistant coatings to enhance longevity and maximise clarity. Polycarbonate can also be tinted, adding to its versatility. While polycarbonate can be pricier than other options, at the end of the day it's worth investing in the right material for the job, as cutting corners can mean early replacements down the line.

 

Clear Pressed Polished Coated Vinyl

Highly scratch resistant, clear pressed and polished coated vinyl is a marine grade window material with outstanding durability. It features a clear thermoplastic vinyl base that is coated with a protective layer.

 

It is then pressed and polished into a flexible, clear sheet that can be easily rolled apart if desired. Clear pressed and polished coated vinyl not only provides excellent clarity, but also resists exposure to corrosive chemicals, including sunscreen, insect repellents and fuel vapors.

 

Polyester and Vinyl composites

Polyester and Vinyl composites are favored for their flexibility in bending and molding along the fluid contours of the boat. In addition to being water resistant, vinyl and polyester composites are mold and mildew resistant, which maximizes transparency and minimizes maintenance. This is always an advantage for boat owners who want to keep their boats looking sharp and seaworthy.

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

Development Background of LED Diffuser Sheet

Led diffuser plate  is an important part from the past to now. Glass was used as the lampshade initially, but the glass was not brittle and the diffusion effect of light was not very good. It was difficult to meet the lighting requirements. Later, it gradually developed to replace glass with resin, but if only transparent resin lampshade, although the light transmittance is high, the basic can reach more than 90%, but the light diffusion effect is not ideal, poor light concealment. The white resin, whose light transmittance is too low, seriously affects the illumination of the LED lamp. In this case, techniques such as adding milky white pigments and surface scrubbing aids are used. Although this solves the issue of light source shielding, there is an excessively low light transmittance, which seriously affects the efficacy of LED lighting. Therefore, the problem of diffusion masks has been plagued by problems. In such a contradictory problem of light rate and light source shieldin...

Is Acrylic Suitable for Lights?

When decorating a room, in addition to some decoration materials, you also need to install lamps and lanterns. Because lamps and lanterns are very important in people's life and can provide lighting. In the dark night, you can work and live as in the daytime. In recent years, acrylic lamps are especially popular. There are many types of acrylic lamps, and people may not know how to choose when they are choosing. In this blog post, I will give you details on how to choose acrylic lights and what to look for when installing acrylic lights .   The advantages of acrylic lights Color The color is very durable. Acrylic panels are glossy, bright and colorful, and the colors are durable for 5-8 years. In other words, it will not change or fade in 5-8 years. Transparent High light transmission. Transparent  acrylic sheets  provide over 90% light transmission. The built-in light source provides uniform and soft nighttime brightness. Compared to neon, acrylic letters as a whole are ...
