Materials

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

 

We produce customized products to satisfy in the best way all your requirements. To make this possible is necessary to start from the best raw materials.

We can help you in the development of each single compound in order to satisfy particular specification or international norms in the automotive, electrodomestics, gas, drinking water, feed sectors… …

We transform black and colored elastomers with hardness from 30 to 90 Shore.

The quality of raw materials is confirmed by the severals certifications obtained in the international accredited labours.

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°
