GPO3 Machining-Industrial Plastics Material

So,  GPO3 Engineering Industrial Plastics Material is a blend of Fiberglass with a polyester resin. Hence the result is Materials that offer excellent ark and track resistance. In addition, various grades of GPO Materials are available in Sheet, rod, tube and shape forms. Also, a particularly popular grade of GPO is GPO3. Perhaps the reason why many Technical departments specify this grade due to its high temperature Insulation capabilities.

Especially relevant, based on the needs of its application, GPO comes in several grades. Also, they are available in Sheet, rod, tube and shapes. Plastic Machining and Plastic CNC G10 Machining also Machining Services.

Hence there are many advantages to using GPO3 Machining Industrial Plastics Material. Most noteworthy being that is highly flame resistant. But also having excellent Electrically Insulating properties with very High strength.

Finally, and importantly, it is also available in a varying catalogued selection of channels & angles.

Sentinel Industrial Plastics Bespoke Parts

All Industrial Plastic Material Machined Parts Manufactured by Sentinel Plastics Ltd, are, customer specific, Bespoke Parts. Thus 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.
