Clear Plastic Guards

Clear Plastic Guards – Covers – Shrouds – Screens – Windows

When choosing your type of Plastic for your Clear Plastic Guard or similar, careful consideration should be taken. For example; is it for impact safety, splash resistance, display protection only , sneeze guard, corner cover or just a simple viewing window. These are just some of the questions you may have to consider when deciding on the correct plastic for the job.

Transparent, Clear Plastic Guard Materials in Brief

Click the links for in depth descriptions.

PETG offers good impact strength, excellent thermoforming and fabrication characteristics, and excellent resistance to chemicals. Easily cut, sawn, drilled, routed and bent. Not scratch resistant unless coated via a secondary opp. Technical term is Polyethylene Terephthalate Glycol.
Polycarbonate, commonly known by the manufacturer’s names of Makrolon GP® and Lexan sheet®. Combining high impact and temperature resistance with optical clarity. Easily cut, sawn, drilled, routed and bent. Polycarbonate is also an excellent candidate for fabricating to use in a wide range of applications. Not scratch resistant unless coated via a secondary opp. Much stronger impact resistance than Acrylic, PVC or PETG.

Lexan Fabrication - Polycarbonate Fabrications - Plastic Fabrication

Experienced Plastic Fabricators – Machined and Assembled Polycarbonate Covers

Acrylic – Data Acrylic is a plastic material with outstanding optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. Extremely popular for retail display. Easily cut, sawn, drilled, routed and bent. The better choice for scratch resistance but offering far less impact strength. The technical name is Poly(methyl methacrylate) (PMMA), and it comes in Extruded or Cast forms. The price of acrylic is cheaper than Polycarbonate and PETG.

PVC has good hardness and mechanical properties, Good electrical insulating properties, Very high chemical & moisture resistance. Equally PVC has excellent forming characteristics, dimensional stability, bondable, self-extinguishing and importantly compared to others fairly inexpensive. Easily cut, sawn, drilled, routed and bent. Not scratch resistant unless coated via a secondary opp. Also loses out against PETG and Polycarbonate on impact resistance. Technically known as Polyvinyl Chloride.

Transparent, Clear Plastic Guard Materials – Some Typical uses.

PETG – Food guarding, its high level of chemical resistance lends it perfectly for use with foodstuffs and in the medical and pharmaceutical sectors.
Polycarbonate – Is highly suited to high protection situations, interior and exterior. Machine guards, vehicle safety screens, Impact guards, Security windows.
Acrylic (Perspex) – Well known for its display preferences. Photo framing, retail display, decorative lighting, lenses, low impact shields, signs and signage, trophies and awards, decorations and jewellery.
PVC Is also commonly used for very similar instances to Acrylic but does not retain the same clarity over time. Signage, fume cabinets, industrial applications, point of sale and finally poster covers.

Sentinel

Machine Guards are most commonly made from Polycarbonate, PETG, Acrylic or Clear PVC.

The close tolerance machinability, transparency and sheer toughness of Polycarbonate make it the ideal material for machine guards. Polycarbonate is available in both general purpose and FDA grades when food contact is a concern. Polycarbonate is also inherently self-extinguishing and can carry a V-0 flame test rating. PETG guards can also be FDA approved and when chemical resistance is a priority.

Clear is the dominant color, but, all of the materials listed above are also available in varying grades of smoke/grey/bronze shades if that is desired.

Plastic Fabricators – Fabricating PETG Guards and Covers.

Plastic Machine Guards

We machine, bend, glue and weld using Polycarbonate, PET-G and Acrylic’s to customer specification, manufacturing robust guards with high visibility that can let you see the product being made and gives you the protection from moving parts.

Go To Plastic Machining. Or Plastic Fabrication.

Firstly, the make up of G10-FR4 materials are an Epoxy Glass based Insulation Plastic. Laminates generally offer high mechanical strength and dimensional stability, are extremely durable, and maintain their properties wet or dry. Therefore the result of this blend is a material that offers excellent ark and track resistance.

Milling

The commonly known G10-FR4 are the most popular grades. G10-FR4 glass cloth reinforced epoxy natural is typically a yellowish to light green color. Epoxy resins are among the most versatile and widely used plastics in the electronics field, primarily because water absorption is virtually nil, rendering it an outstanding insulator.

As a result of being the most economic choice of G10-FR4 material, it is also noteworthy for being a material which can be easily machined to bespoke applications.

Some examples of what G10-FR4 Materials are widely used to manufacture are Insulating supports, high voltage insulation, bus bar supports and mounting panels in electrical apparatus are just some examples.

Based on the needs of its particular application it comes in several grades.

So there are many advantages to using G10-FR4 Machining Materials. Most of all having high structural strength but also excellent Electrically Insulating properties.

Turning

Most noteworthy, raw materials are available in standard sheets & rod sizes.

Finally a couple of important factors. Firstly Sheet thickness ranges from 0.8mm to 50mm.

Sentinel Plastic Engineering Only Supplies Bespoke Parts

All parts manufactured by Sentinel Plastics Ltd are customer specific bespoke plastic cutting parts. Either working from Prototypes, drawings, making a One off or hundreds of parts. Sentinel Plastics has flexibility to meet most requirements.

As well, the material is nearly immune to shrinkage, holding its form factor and dimensional stability at temperatures as high as 285° F. This property makes it ideal for use in electronic equipment with components that generate excessive heat. Should it combust at higher temperatures, the bromine added during the manufacturing process renders it self-extinguishing, another important factor for making its use in aerospace engineering so prominent.
