Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt. % to 75 wt. % of an polyamide, from 2 wt. % to 40 wt. % of an etchable filler, from 10 wt. % to 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance to injection-molded articles that are substantially free of visual defects.

Abstract: Provided herein are polyamide compositions including one or more semi-crystalline polyamides and either an amorphous polyamide or a semi-crystalline copolyamide such as PA66/6. The provided compositions are particularly useful as vibration isolators more effective at high-temperature noise and harshness damping than conventional polyamide compositions. Also provided are methods for making the provided compositions, and articles that include the provided compositions.

Abstract: Provided herein is a polymer composition comprising an aromatic polyamide comprising terephthalic units and isophthalic units or a 6T/DT copolymer and having an overall high aromaticity, with a heat stabilizer and/or a lubricant. The polymer composition demonstrates improved electrical performance in terms of volume resistivity and dielectric strength.

Abstract: A terpolymer composition is described that contains a statistical amount of 50-98 wt % of a first repeating AA-BB comonomer unit; 1-25 wt % of a second repeating AA-BB comonomer unit; and 1-25 wt % of a repeating lactam comonomer unit or 1-25 wt % of a third repeating AA-BB comonomer unit, where the terpolymer composition exhibits a high melting point similar to that of PA66 while also exhibiting a significantly reduced crystallization rate and crystallization temperature.

Abstract: A polyamide composition comprising from 45 wt % to 95 wt % of polyamide polymer and from 5 wt % to 55 wt % of a modifier comprising a C18-44 dimer acid or a C18-44 dimer amine or a combination thereof. A number average molecular weight of the polyamide polymer is less than 30,000 g/mol. The polyamide composition has a chemical resistance, as measured by exposure to HCl (10%) for 14 days at 58° C., resulting in a weight loss of less than 3.0 wt %; and a moisture uptake of less than about 2.0 wt % moisture at 95% RH. A process for preparing the polyamide composition is also disclosed.

Abstract: A copolyamide composition comprising a statistical copolyamide containing 70-99 wt % of diamine and dicarboxylic acid repeat units and 1-30 wt % of lactam or AA-BB repeat units, whereby incorporation of the comonomer lactam or AA-BB unit reduces the crystallization rate (longer crystallization times) while maintaining (1) high melting point, (2) low potential plate out, (3) low oxygen permeation, (4) high tensile strength and (5) puncture/tear resistance.

Abstract: A polyamide composition comprising a base polyamide and an elastomer concentrate comprising: 20-80 wt % of an elastomeric aliphatic polyether having a molecular weight ranging from 400-4000 g/mol; and 80-20 wt % of a concentrate polyamide. The polyamide composition has particular uses as a cable tie and demonstrates improved cold-temperature applications while maintaining high strength, good flammability rating, and excellent processability.
