Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related ...
Cast acrylic has a better ability to be reworked hot and it is known for its superior surface finish and optical properties. Also cast acrylic is more scratch resistant than extruded acrylic. Cast acrylic is also preferred over extruded in applications that require machinings, such as turning on Engine Lathe or milling/drilling.
Acrylic resin is a common ingredient in latex paint (UK: "emulsion paint"). Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl.

For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon. [1] It was first developed in the mid-1940s but was not produced in large quantities until ...
Acrylic acid, the simplest acrylic compound; Acrylate polymer, a group of polymers (plastics) noted for transparency and elasticity; Acrylic resin, a group of related thermoplastic or thermosetting plastic substances; Acrylic fiber, a synthetic fiber of polyacrylonitrile
Flour and feed milling is the group's largest segment by sales. [2] The segment comprises FFM Berhad, an 80 percent subsidiary of the group. FFM is the largest flour miller in Malaysia with a total milling capacity of 2,550 megatonnes per day. [9] FFM also operates mills in Vietnam, Thailand and China through associate companies. [9]
There are two alkyl chains commonly used in surfactants: polyethylene oxide and polypropylene oxide. Polyethylene oxide chains have an oxygen and two carbon (-O-CH 2-CH 2-) n repeating unit and has an increased hydrophilic character compared to hydrocarbons. Polypropylene oxide has the same backbone structure as polyethylene oxide but with a ...
In most of the cases, 10% amounts of other vinyl comonomers are also used (1–10%) along with AN depending on the final application. Comonomers include acrylic acid, acrylamide, allyl compounds, and sulfonated styrene. [2] Anionic polymerization also can be used for synthesizing PAN.
