What is Vamac rubber?
Vamac® ethylene acrylic elastomers are specified for a variety of demanding automotive applications, including electric and hybrid vehicle components. It can be formulated to provide excellent resistance to extreme temperatures and fluids. Typical applications include: Powertrain components. Air management systems.
What does Vamac stand for?
With the company’s new location and early expansion, in 1970, Virginia Machinery and Well Company abbreviated its name to VAMAC, Inc.
What is AEM polymer?
AEM rubbers (Ethylene acrylic elastomers) are synthetic rubbers composed of both ethylene and acrylic monomers. The ethylene imparts good low temperature properties, while the acrylic portion improves the oil resistance.
What does FKM material mean?
fluoroelastomer
What is FKM? FKM is the ASTM designation for a class of fluorinated, carbon-based synthetic rubber, commonly known as fluoroelastomer. FKM has impressive heat resistance, allowing FKM seals to withstand temperatures greater than 200°C.
Is rubber an acrylic?
Acrylic rubber, known by the chemical name alkyl acrylate copolymer (ACM) or the tradename HyTemp, is a type of rubber that has outstanding resistance to hot oil and oxidation. It belongs to specialty rubbers. It has a continuous working temperature of 150 °C (302 °F) and an intermittent limit of 180 °C (356 °F).
What is ACM chemical?
Acrylic rubber, known by the chemical name alkyl acrylate copolymer (ACM) or the tradename HyTemp, is a type of rubber that has outstanding resistance to hot oil and oxidation. It belongs to specialty rubbers.
What is polyacrylic rubber?
Polyacrylic elastomers, also called ACM rubbers / Polyacrylic Rubber, are synthetic elastomers composed of acrylic monomers. These polymers are usually prepared by emulsion or suspension polymerization. The main repeat units are ethyl and butyl acrylate or a blend of both.
What are ACM materials?
Aluminum composite material (ACM) is a three-layer sandwich panel consisting of two pre-painted aluminum sheets bonded to a polyethylene (PE) core. ACM panels are an excellent material for indoor or outdoor applications that require good dimensional stability, low weight, and a sleek, brilliant look.
What is ACM elastomer?
ACM elastomers are made of polar acrylic acids. As polar materials, they display good resistance to high-additive lubricating oils. Due to its saturated¹ main chain, the material exhibits good resistance to ozone, weather and heated air.
What are properties of ACM?
Key properties of ACM at a glance:
- Very good weather, ozone and hot air resistance.
- Moderate strength.
- Low elasticity.
- Thermal stability from -30 to +150°C, up to +160°C for short periods.
- Relatively poor low-temperature performance.
- Good resistance to mineral oils.
- Moderate resistance to fuels.
- Average rebound resilience.
What is the composition of nitrile rubber?
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.
What is nitrile formula?
A nitrile is an organic chemical that contains a cyano functional group (subunit), CN-, in which the carbon and nitrogen atoms have a triple bond i.e. C≡N-. The general chemical formula of a nitrile is RCN, where R is the organic group.
What is a Pacm ACM?
OSHA requires that building owners identify presumed asbestos-containing material (PACM) in their buildings and treat the PACM as asbestos-containing materials (ACM) until the materials are proven not to contain asbestos.
