Aluminium silicate: contains 20% alumina, often with calcium oxide, magnesium oxide and boric acid in relatively small quantities and with very small amounts of sodium or potassium silicate. It can withstand temperatures of 750° C and thermal shock. The glass is commonly used in combustion tubes and glass for level gauges or high-pressure steam boilers.
Anti-reflective glass: etched or coated glass to reduce reflection. The disadvantage of coated glass is that it reveals fingerprints. This glass is mainly used for screens, touch screens etc.
Borosilicate glass: Also known as Pyrex or Boro Float Glass. Suitable for temperatures up to 500° C. This glass is harder and more difficult to manipulate than float / window glass.
In hardened form suitable for temperatures up to 300° C and resistant to many mediums. Borosilicate glass is the standard material for viewing and gauge glasses according to DIN 7080 and 7081.
Glass filter: for example: UV block filters, signal filters, heat reflection filters etc.
Tempered glass: This glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Toughened glass is physically and thermally stronger than regular glass. Tempered glass cannot be cut or otherwise processed. Other types of glass may also be toughened.
Coloured glass: For example, in blue in order for a better view of the fire or red and green light filters glass strips for the benefit of a sight glass device.
Laminated glass: Is float / window glass consisting of two or more layers and crystal clear silicone adhesive, glue or laminated PVB foil. Also other types of glass can be laminated.
Glass Tubes: we supply standard uncured 3.3 borosilicate glass for use in level gauges. Also available with quartz glass on request.
Gorilla Glass: very strong thin glass (0.4 to 1 mm thick), mainly used in touch screens, smarthphones, laptops a.o.
Quartz glass: suitable for high temperatures up to 1,200° C and very suitable for optical purposes. Good transmission of infrared and ultraviolet.
Soda-lime glass: also known as press center glass. This hardened type of glass is suitable for temperatures up to 150° C. It is used in situations without high pressure, temperature and/or chemical resistance requirements.
Round sight glasses to DIN 8902 up to 150° C, 100° C sight glasses to DIN 8903.
Plexiglass: also known as acrylic glass and PMMA. It is not suitable for high temperatures and is resistant to many oils and chemicals. It obsoletes eventually and will then fade and crack. We supply plexiglass as tubes, plates, sight glasses and rings.
Robax glass: also known as neoceram glass. It is an extremely heat-resistant, transparent glass ceramic which can be produced in a wide variety of shapes and sizes to meet your specific needs. Resistant to temperatures of 750°C and large temperature fluctuations and / or shocks to 750°C. Up to 90% of the infrared heat is let through. This glass is widely used in fireplaces, stoves and boilers.
Vycor glass: is (almost) no longer available. It was produced by Corning Glass in the United States and is only available in relatively small sizes. It is suitable for high temperature and pressure, with a unique combination of pressure and high temperature resistance. An alternative is quartz glass, which however has less pressure resistance.
