Foamable halogenated polymers comprising the multi-stage emulsion processing aid polymer is also provided. Also provided are methods for making the multi-stage emulsion processing aid polymer and foamable halogenated polymers.

A composition comprises, based on the total weight of the composition, 45 wt % to 75 wt % of a polyetherimide; and 20 wt % to 45 wt % of talc; and 5 wt % to 15 wt % of a fluorinated polymer; wherein the composition has a number of drops to tracking at 250 volts of greater than or equal to 50 drops according to ASTM D-3638-85.

A coating agent for oil seal comprising 10 to 160 parts by weight of a filler having a particle size of 0.5 to 30 m based on 100 parts by weight of isocyanate group-containing 1,2-polybutadiene and being prepared as an organic solvent solution, wherein a contact angle between a substrate surface coated with the coating agent and engine oil is less than 35. The coating agent can improve wettability with oil and reduce dynamic friction coefficient in oil, while increasing the roughness of the coating surface. Thus, low torque characteristics can be achieved, while maintaining excellent seal performance inherent in oil seal.

An electrical steel sheet has an insulating coating on a steel sheet surface. The insulating coating includes one or more selected from an inorganic salt, an oxide, and an organic resin. The insulating coating includes the inorganic salt and/or the oxide in an amount of 50% or more by mass in total based on the total mass of the insulating coating. The insulating coating has a fluorine concentration ranging from 2 ppm to 130 ppm. The insulating coating is free of a chromium compound. The insulating coating of this electrical steel sheet has excellent coating compatibility.

A method and system for the production of fibers for use in biocomposites is provided that includes the ability to use both retted and unretted straw, that keeps the molecular structure of the fibers intact by subjecting the fibers to minimal stress, that maximizes the fiber's aspect ratio, that maximizes the strength of the fibers, and that minimizes time and energy inputs, along with maintaining the fibers in good condition for bonding to the polymer(s) used with the fibers to form the biocomposite material. This consequently increases the functionality of the biocomposites produced (i.e. reinforcement, sound absorption, light weight, heat capacity, etc.), increasing their marketability. Additionally, as the disclosed method does not damage the fibers, oilseed flax straw, as well as all types of fibrous materials (i.e. fiber flax, banana, jute, industrial hemp, sisal, coir) etc., can be processed in bio composite materials.
