They have high heat and oxidative stability, outstanding low temperature flexibility, and are resistant to many chemicals, weathering, ozone and sunlight (UV). VMQ is usually vulcanised with peroxides.
The vulcanisates have to be annealed in order to stabilise their mechanical properties. VMQ silicone rubber is synthetic, non-reactive, stable, and resistant to extreme environments and temperatures found across a wide array of industries. VMQ rubber compounding VMQ (blue frame) improves vulcanisation rate, compression set, resilience and oil resistance.
These elastomers have excellent cold flexibility (can reach temperatures of -°C) as well as high thermal resistance (up to 200°C, with special compounding up to 300°C for short periods of time). Electrical properties are excellent and resistance to weathering and ozone attack is outstanding. Silicone Rubbers are ideal for high and low temperature applications.
Silicone VMQ -MQV Questa sigla internazionale identifica il Silicone. Il Silicone, oltre ad avere ottime resistenze alle temperature ed all’ozono, UV, oli vegetali ed animali, possiede ottime caratteristiche di-elettriche. Adatto all’esposizione con ozono ed agenti atmosferici, ma assolutamente non compatibile con i carburanti e gli oli.
The world of silicone rubber is full of confusing acronyms. To an outsider, the names of some compounds can seem like a foreign language, potentially leading to confusion and misinterpretation. However, there are standardised names for the materials we use, as defined by the ISO. Le speciali proprietà degli elastomeri siliconici sono il risultato della loro particolare struttura chimica.
Sono unici nel loro genere in quanto combinano le qualità della silice, carica minerale, con quelle tipiche dei composti organici. Sien den besten Sale? Industrial grades of silicone rubber are generally based on polydimethylsiloxanes, partially substituted with other organic groups such as alkyl, vinyl or phenyl, which regulate respectively the processability, reticulation and resistance to low temperatures.
The main features of silicon rubber are to maintain good elasticity values even at extreme temperatures, in particular in pneumatic applications, where they are only mildly affected by the aging phenomenon. To create this class of synthetic elastomers, pendant organic groups such as methyl, phenyl and vinyl are attached to silicon atoms.
FVMQ has a good heat resistance, very good low temperature flexibility and excellent resistance to weather, ozone and UV rays. Compared to VMQ the temperature range is slightly reduced from -50°C to 180°C.
It has a fairly low tensile strength and a moderately high ductility among rubber materials. This material should be used for static sealing as Silicones have poor tensile strength, tear resistance, and abrasion resistance.
Silicone rubbers ( VMQ ) offer wide temperature ranges and low temperature flexibility. Retention of properties of silicone at high temperature is superior to most other elastic materials. About VMQ Silicones.
VMQ (Silicones) are a group of elastomeric materials made from silicone, oxygen, hydrogen, and carbon. Extreme temperature range and low temperature flexibility are characteristics of silicone compounds. As a group, silicones have poor tensile strength, tear resistance, and abrasion resistance. In addition to being generally inert (non-reactive), silicones are odourless, tasteless, non- toxic, and fungus resistant.
It shows an excellent temperature resistance and is an outstanding material for O-rings. However it makes up for that with a great resistance to extreme temperatures.
This is used for applications when there is a need for heat stability (-70°C up to 3°C). It has very good electrical insulation properties and offers good weathering and ozone resistance.
They are very clean and are used in many food and medical applications because they do not impart odor or taste. Rubber -derived contact adhesives may be used with various surfaces like glass, metal, and natural fibres.
