Stress crack formation. UV resistance of plastics is usually achieved by the use of additives such as UV stabilizers, black coloration (typically using carbon black) or protective surface coatings (such as paint, or metallization). The addition of carbon black is a low cost and typically very effective way of creating UV resistant plastics. Ordinary glass is also not UV-resistant, and most acrylic plastics and paper don’t allow UV-C to pass through. In addition, even thin sheets of acrylic are not very effective in blocking UV. There are no suitable transparent media that are 100% UV-C transparent, so you’ll have to use reflective optics to prevent UV damage. Acrylic glass is clearer than regular glass, but that benefit is short-lived if the plexiglass sheet is exposed to UV rays and direct sunlight. Certain types of acrylic plastic glass will yellow when exposed to sunlight, which can be unattractive and give it a low-quality appearance. However, as mentioned earlier, plexiglass is also UV resistant. AR polycarbonate is specialized plastic sheeting that offers higher UV and abrasion resistant qualities than standard polycarbonate sheeting while maintaining its best qualities. Our abrasion and scratch resistant polycarbonate has unrivaled impact, strength and clarity qualities, along with a 7-year warranty against loss of light transmittance Similarly, acrylic wins the battle for flexural strength at 115 MPa vs. 90 MPa for polycarbonate—set a heavy object on unsupported sheets of each and PC will give way first (but not by much). Both polymers are quite impact resistant, but where acrylic comes in around 17 times that of glass, polycarbonate boasts a whopping 250x increase. . Acrylic plastic, also known by many names like PMMA (Polymethyl methacrylate), Plexiglass, Plexiglas, etc., is a transparent thermoplastic material known by its chemical name “plexiglass,” with excellent strength, rigidity, and optical clarity. The material has many similarities with Polycarbonate and, due to its high impact resistance, is Although made primarily for artwork, the Krylon UV-Resistant Clear Gloss is an excellent UV protectant spray for most hard and soft surfaces. It creates a permanent clear gloss coating to shield surfaces like metal, wood, plastic, ceramic, plaster, glass and even paper from harmful UV rays and moisture. Starboard is a plastic sheet material made of High-Density Polyethylene (HDPE) and infused with UV inhibitors. In fact, it’s one of the few materials that is nearly impervious to UV exposure. This makes it highly durable, even in the harshest weather. Starboard material will never rot, delaminate, or fade. These are the five best UV-resistant plastics on the market today. Acrylic. High Density Polyethylene (HDPE) Polycarbonate. Polyamide-Imide (PAI) Polyvinylidene Fluoride (PVDF) Improving UV resistance in plastics. Start making parts with UV-resistant plastics. Since the paint is only slightly water-resistant and not waterproof, the rain will most definitely ruin it. If you have not treated the surface in any way and the paint is still wet, the rain can wash away the acrylic paint. When the paint has dried, it is slightly water-resistant but will eventually start to peel or flake off.
