MVQ – is an elastomer based on methyl-vinyl silicone rubber. In compare with other rubbers, MVQ has low mechanical characteristics, therefore primarily used for production of static parts. MVQ has excellent ozone, weather and ageing resistance. The oil compatibility depends on the content of aromatic hydrocarbons in the oil.
MVQ is soot free and is suitable for electrical insulation
Temperature range: from -60° up to +200°C (short term up to +230°C). Swelling in mineral oils is low, but depends very much on the composition of the oil. The compatibility with additivated oil is better, than in case with NBR. MVQ has a high gas permeability.
|Good resistance||Low resistance|
|Engine and transmission oil of aliphatic nature, also sulfur oils||Aromatic mineral oils|
|Brake fluids based on glycol||Fuel|
|Adipose and vegetable oils||Silicone oils and grease|
|Water||Aromatic hydrocarbon (toulene, benzol)|
|Fire-resistant pneumatic fluids HFD-R (phosphoric acid ester) and HFD-S(chlorinated hydrocarbons)||low molecular weight chlorinated hydrocarbons (trichlorethylene)|
|Dilute salt solutions||Overheated steam up to 120°С (only short time steam sterilization is possible)|
|–||Acids and alkalis|
MVQ can be used for production of O-Rings and other seal parts. MVQ is mainly used in cases where are no other alternatives because of high temperatures and chemical stress. Due to its low mechanical properties use should be reduced to static application.
MVQ is used as a sealing material in the pharmaceutical and food industry.
- Special seals in the chemical and food industry
- Rotary shaft seals for special use
