Clareza e beleza para tornar atraente todas as aplicações

As chapas de acrílico extrudado compacto (PMMA) PALGLAS oferecem claridade, transmissão de luz e resistência a UV comparáveis às do vidro, mas com a metade do peso. Disponíveis em transparente e em cores translúcidas e opacas padrão, além de cores personalizadas (sujeito a quantidades mínimas), as chapas PALGLAS abrem um mundo de opções para os projetistas, incluindo pequenas peças fabricadas ou moldadas, exibidores POP, itens de sinalização e móveis transparentes. Mesmo aplicações como barreiras acústicas em estradas podem ser projetadas com um senso de arte e estilo, graças à sua resistência aos gases emitidos pelos veículos. Seja em corte, maquinado, dobra ou acabamento, as chapas acrílicas PALGLAS são fáceis de trabalhar. Com apenas algumas poucas ferramentas além daquelas encontradas normalmente no comércio, você pode utilizar o material com diversos métodos para obter um produto acabado. PALGLAS é apenas um dos muitos produtos que a Palram oferece para esses segmentos de mercado.

Perguntas Frequentes

What are three-dimensional or 3D logo signs?
+ -

3D letters and/or 3D logos are made of plastic, metal or foam. They reinforce an upscale image and create a clear highlighted message. These signs can be illuminated when required.

Should products be pre-dried before thermoforming?
+ -

This depends on the production date and storage conditions of the product before thermoforming. It is recommended to check the product before thermoforming is attempted.

Is the PE film suitable for thermoforming applications?
+ -

Most of Palram's products that are delivered with PE film covering are suitable for thermoforming. In general, we recommend using clear PE and not printed PE.

How do I polish the edges of acrylic?
+ -

Acrylic edges can be polished by heating them with a torch, blowing hot air on them, or rotating a brush with wax.

Can the percentage of light transmission be controlled? I need a lot of light but I need it to be diffused.
+ -

Palram offers various LT% parameters - from 0% to 90%. In addition, we offer a color called a “diffuser” that allows 85% of the light in while diffusing it by 100%. The result is a light-transmitting panel that is not transparent but is highly translucent.

How do I design the secondary steel support spacings for roofing/siding?
+ -

Palram created specific loading tables for each product. Please visit our website and download the specific catalog.

What is the meaning of Shading Coefficient (SC)?
+ -

Shading coefficient (SC) is a parameter that compares transparent and translucent materials with clear 3 mm glass with 87% LT ׂ(light transmission). The lower the value, the more convenient it is to stay under the material on warm, sunny days. In architectural projects, the SC should usually be between 0.3 to 0.5.

Which of Palram's sheets are suitable for printing, sign & display applications?
+ -

For use in illuminated signage, PALSUN, PALSUN CS (Coil Stock) and PALGLAS are suitable for the sign face; and PALBOARD, PALOPAQUE, and PALIGHT for the body of the letters or symbols. For print & display, Palram's entire product portfolio can be used based on the specific application. This choice depends on a combination of several parameters, including the cost of the media, its durability, and its suitability for the specific application. Please visit Palram’s Flat sheet application catalog for more information.

Which materials can be used in the construction of my sign?
+ -

Sign faces are usually made from polycarbonate or acrylic. For extreme conditions such as heavy hail, low temperatures, or high temperatures produced when thermo-forming, polycarbonate is probably more suitable. For sign boxes or channel letter cans, PVC, multi-layered PVC and foam PVC can be used.

Which material diffuses the light better?
+ -

The diffusion is not defined by the material, but by the diffusion additive that is part of the manufacturing formula. The materials should be selected by their fit to the application (e.g. polycarbonate for thermo-forming or extreme weather). Usually products marked with sign grade and/or diffusion grades have greater light diffusion than others.

What is an illuminated sign?
+ -

A sign that is illuminated by an electrical light source (fluorescent\LED).

What is the most accurate white point that is suitable for wide-format printing?
+ -

There are different white substrates available but in order to achieve a true colored image according to the design, a process of profiling (ICC profile) needs to be done. By using a natural white substrate (a tint which been made with no extra additives), the process of measuring and profiling becomes very simple and fast.

How do I handle inkjet printable media before and after printing?
+ -

Before: use a protected sheet with PE masking, store unused inkjet printable media in original packaging and in a clean area, and avoid touching the print side by handling the edges of the sheet or by using lint-free white gloves.

After: avoid any finishing until prints are completely dry, store the printed media in a clean environment, and avoid dust from sticking to the fresh cured ink.

What is the difference between a polypropylene sheet and PVC?
+ -

In terms of ink adhesion properties, both polymers act very differently. PVC is a ready-to-use polymer so no pre-treatment needs to be done before printing (on rigid or flexible media). Polypropylene has different chemical properties and for this reason, needs to get a pre-treatment coat ('Corona'), which has a limited shelf life.

What is the best wide-format inkjet media (substrate) for my application?
+ -

This is based on a combination of several parameters, but the main ones are the cost of the media and its durability, and its fit to the required application. Please visit Palram’s Flat Sheet Application Catalog.

What can assure accurate double-sided printing or recto verso prints?
+ -

A strict spec of diagonal (from angle to angle) during the production process is feasible for this.
