38mm Clear Air Bubble Extruded Acrylic Rods

Specifications

Product Name: 38mm Clear Air Bubble Extruded acrylic rods

Description

PMMA is a tough, highly transparent material with excellent resistance to ultraviolet radiation and weathering. It can be coloured, moulded, cut, drilled, and formed. These properties make it ideal for many applications including airplane windshields, skylights, automobile taillights, and outdoor signs. 

Like all plastics, acrylics are polymers. The word polymer comes from the Greek words poly, meaning many, and meros, meaning a part. A polymer, therefore, is a material made up of many molecules, or parts, linked together like a chain. Polymers may have hundreds, or even thousands, of molecules linked together. More importantly, a polymer is a material that has properties entirely different than its component parts.

FAQ

1.How UV and weather-resistant is PMMA?

Crystal-clear PMMA shows excellent resistance to aging and weathering, including natural UV radiation. Therefore they do not turn yellow or become brittle even after many years of outdoor exposure to various climates around the world. PMMA retains its superior optical and mechanical properties for many years.

2.What is the chemical resistance (compatibility) of PMMA?

PMMA is generally characterized by good chemical resistance. Parts made from PMMA are resistant to most inorganic chemicals, aliphatic hydrocarbons, cycloaliphatic compounds, fats and oils at room temperature, and also to diluted acids and concentrated solutions of most alkalis at temperatures up to 60 degrees Celsius. By contrast, PMMA is attacked by chlorinated hydrocarbons, ketones, esters, ethers, alcohols and aromatic compounds.

3.How abrasion-resistant is PMMA?

PMMA shows the greatest surface hardness and thus the best abrasion resistance of all thermoplastics. The high gloss is therefore retained even after prolonged utilization.

4.How does cast and extruded PMMA differ in terms of their properties?

Optical properties

Since cast PMMA is manufactured by cell casting between two sheets of mirror-like glass, it has excellent surface quality. Extruded PMMA is manufactured in a special extrusion process and therefore cannot always match the high optical quality of cast PMMA.

Machining

Cast PMMA offers greater scope for fabrication, which means the machining conditions do not have to be observed with such accuracy. Less scope is available with extruded PMMA, and care must be taken to ensure the correct tools are used in order to obtain clean cuts and drill holes, if necessary using cooling lubricants.

Thermoforming

Extruded PMMA allows more economical solutions during thermoforming because the forming cycles are shorter and contours can be more accurately reproduced.

Permanent service temperature

The permanent service temperature of cast PMMA is 85 degrees Celsius (°C), about 10°C higher than extruded PMMA.

Chemical resistance

Owing to its higher molecular weight, cast PMMA shows better chemical resistance.

5.Is there a guarantee for PMMA sheet products?

Typically PMMA manufacturers guarantee their products for 10 years and a number of producers guarantee for up to 30 years, against yellowing and retaining high light transmission for 30 years.
