Werkstoffe

-----------------------------------------------------

 

A.T. Gomma fertigt Produkte um am besten eure Bedürfnisse zu befriedigen.

Um dies zu ermöglichen, muss von den besten Rohstoffen ausgegangen werden.

Wir unterstützen Sie bei der Entwicklung jeder Mischung, um bestimmte Spezifikationen oder internationale  Vorschriften im Automobilsektor, Haushaltsgerät, Gas, Trinkwasser, Lebensmittel usw. zu erfüllen.

Wir transformieren Elastomer schwarz und farbig mit Härte von 30 sh. bis 90 sh.

Die Qualität der  verwendeten Rohstoffe  wird durch die zahlreichen Homologationen  bestätigt, von akkreditierten  Internationalen Instituten erhalten.

Not affected by temperature changes, excellent  insulator and when properly formulated perfect no toxicity and possibility of conductive grades.

 

+200°C          (special series to  300° C)

Good in water and aqueous solutions, to exposure to atmospheric agents, ozone and U.V. vegetable and animal oils and glycols.

 

VMQ

SILICONE

 

FVMQ

FLUOROSILICONE

Similar to silicone but with higher chemical resistance against lubrificant oil,ecc.

<=100°C/ 110°C

Good in aliphatic hydrocarbons, minerals oils, ozone and UV, fair in petrol.

Excellent resistance against chemical agents, lubrificants, heat and flames. Outstanding behavior  to compression set. Excellent behavior with ozone and U.V rays.

 

-25°C>+280°C (special grades -30°/40°

Special chemical agents with excellent resistance in a wide temp. range, as: aliphatic, chlorinated, aromatic, hydrocarbons, fuel, mineral and vegetal oils fats, hydraulic fluids.
