Description

22SHPP0027-WO-PCT (SS230141PCT) THERMOPLASTIC COMPOSITION, METHOD FOR THE MANUFACTURE THEREOF, AND ARTICLES MADE THEREFROM CROSS REFERENCE TO RELATED APPLICATION This application claims priority to and the benefit of European Patent Application No. 22192155.4, filed on August 25, 2022, the contents of which are hereby incorporated by reference in their entirety. BACKGROUND [0001] This disclosure relates to polycarbonate compositions, methods of manufacture thereof and to articles comprising the same. [0002] Polycarbonate (PC) are used on a large scale for many applications, including, for example, electronics, mobility, industrial, infrastructure, and healthcare due to their good mechanical, electrical, and flame retardant properties and wide color space. Products with a smaller carbon footprint are becoming more desirable. Post-consumer recycling (PCR) can enable reuse of plastic materials by recycling from final products in the market and converting to raw materials for new products. However, PCR-based materials typically exhibit inferior mechanical properties compared to the corresponding virgin materials, for example due to additional thermal history or degradation that may occur in the recycling process. Moreover, some PCR materials may have color, which may lead to a narrow color space available for final products. [0003] Accordingly, there remains a continuing need for compositions comprising recycled materials which exhibit comparable mechanical properties, flame retardant performance and color space relative to virgin materials. It would be particularly advantageous to provide a composition having a high PCR content. SUMMARY [0004] An aspect of the present disclosure is a thermoplastic composition comprising: 30 to 95 weight percent of a post-consumer recycle polycarbonate; and 5 to 70 weight percent of a polycarbonate-siloxane copolymer, or a polycarbonate-ester, or a branched polycarbonate, or a copolycarbonate comprising carbonate repeating units derived from a bulky bisphenol group; and wherein when the composition comprises the polycarbonate-siloxane copolymer, the branched polycarbonate, or the copolycarbonate comprising phthalimidine carbonate repeating units, the composition further comprises 5 to 65 weight percent of a linear polycarbonate 22SHPP0027-WO-PCT (SS230141PCT) homopolymer comprising at least two of an ultra high flow polycarbonate having a melt flow rate of 55 to 85 g/10 minutes, as determined according to ASTM D1238 at 300°C and 1.2 kg; a high flow polycarbonate having a melt flow rate of greater than 20 to 54 g/10 minutes, as determined according to ASTM D1238 at 300°C and 1.2 kg; a low flow polycarbonate having a melt flow rate of 5 to 19 g/10 minutes, as determined according to ASTM D1238 at 300°C and 1.2 kg; and an ultra-low flow polycarbonate having a melt flow rate of less than 5 g/10 minutes, as determined according to ASTM D1238 at 300°C and 1.2 kg; wherein weight percent of each component is based on the total weight of the composition. [0005] Another aspect of the present disclosure is A method for the manufacture of the composition, the method comprising melt-mixing the components of the composition. [0006] Another aspect is an article comprising the composition. [0007] The above described and other features are exemplified by the following detailed description. DETAILED DESCRIPTION [0008] The present inventors have discovered a composition comprising particular amounts of post-consumer recycle polycarbonate, a polycarbonate component (e.g., a virgin polycarbonate), and a combination of linear polycarbonates having particular melt flow rates can provide a desirable combination of properties. [0009] Accordingly, an aspect of the present disclosure is a thermoplastic composition. The thermoplastic composition comprises a post-consumer recycle polycarbonate. As used herein, the term “post-consumer recycle polycarbonate” refers to a polycarbonate that has been previously used in end-use parts, articles, or components, and has been collected or reclaimed after utilization by the end-user or consumer. Thus, for example, it is understood that that the term refers to a polycarbonate material that would have otherwise been disposed of as waste but has instead been collected and recovered (reclaimed) as a material input, in lieu of a new virgin material, for a recycling or manufacturing process. The term is inclusive of such collected or reclaimed materials which have been further treated or processed to facilitate re-use of the material. Thus, for example, the term is inclusive of material that has been reprocessed from collected or reclaimed material by means of a manufacturing process and made into a product or into a component for incorporation into a product. Such recycled polycarbonates can be further processed to ground materials, flakes, or in the form of pellets. [0010] The post-consumer recycle polycarbonate comprises a polycarbonate. “Polycarbonate” as used herein means a homopolymer or copolymer having repeating structural carbonate units of formula (1) 22SHPP0027-WO-PCT (SS230141PCT)

A combination of additives can be used, for example a combination of a stabilizer (e.g., a heat stabilizer), a flame retardant, and a color package. In general, the additives can be used in the amounts generally known to be effective. For example, the total amount of the additives (other than any impact modifier, filler, or reinforcing agent) can be 0.001 to 10.0 wt%, or 0.01 to 5 wt%, each based on the total weight of the polymer in the composition. [0059] In an aspect, the composition can optionally further comprise a flame retardant. Useful flame retardants can include organic compounds that include phosphorus, bromine, or chlorine.

[0078] Physical measurements were made using the tests and test methods described below. [0079] Tensile properties were measured in accordance with ASTM D638 or ISO 527 at a test speed of 50 mm/min on standard tensile bars. [0080] Flexural properties were measured in accordance with ASTM D790 at a test speed of 2.54 mm/min or ISO178 standard at a test speed of 2 mm/min. [0081] Notched Izod impact Strength (INI) was determined in accordance with ASTM D256 under a load of 5 lbf at different temperatures including a temperature of 23°C, -20°C, or -30°C. All ASTM INI determinations were carried out on sample plaques of 3.2 mm thickness. For the test at -20°C and -30°C, the test specimens were placed in the freezer for more than 4 hours then taken out for testing at room temperature within five seconds. [0082] Heat deflection temperature (HDT) was determined in accordance with ASTM D648 under a load of 1.82MPa , ISO 75/Af under a load of 1.8MPa or ISO 75/Bf under a load of 0.45MPa. [0083] Light transmission and haze were characterized according to ASTM D1003 using a color chip having a thickness of 2.54 millimeters. 22SHPP0027-WO-PCT (SS230141PCT) [0084] Flammability tests were performed following the procedure of Underwriter’s Laboratory Bulletin 94 entitled “Tests for Flammability of Plastic Materials for Parts in Devices and Appliances” (ISBN 0-7629-0082-2), Fifth Edition, Dated October 29, 1996, incorporating revisions through and including December 12, 2003. Several ratings can be applied based on the rate of burning, time to extinguish, ability to resist dripping, and whether or not drips are burning. According to this procedure, materials can be classified as UL94 HB, V-0, V-1, V-2, 5VA, or 5VB. The test specimens were aged at 23°C, 50% RH for more than 2 days or 70°C for 168 hours before testing. Specifically, in the UL 9450W (20 mm) Vertical Burning Flame Test, a set of five flame bars was tested. For each bar, a flame was applied to the bar then removed, and the time required for the bar to self-extinguish (first afterflame time, t1) was noted. The flame was then reapplied and removed, and the time required for the bar to self-extinguish (second afterflame time, t2) and the post-flame glowing time (afterglow time, t3) were noted. To achieve a rating of V-0, the afterflame times t1 and t2 for each individual specimen must have been less than or equal to 10 seconds; and the total afterflame time for all five specimens (t1 plus t2 for all five specimens) must have been less than or equal to 50 seconds; and the second afterflame time plus the afterglow time for each individual specimen (t2 + t3) must have been less than or equal to 30 seconds; and no specimen can have flamed or glowed up to the holding clamp; and the cotton indicator cannot have been ignited by flaming particles or drops. To achieve a rating of V-1, the afterflame times t1 and t2 for each individual specimen must have been less than or equal to 30 seconds; and the total afterflame time for all five specimens (t1 plus t2 for all five specimens) must have been less than or equal to 250 seconds; and the second afterflame time plus the afterglow time for each individual specimen (t2 + t3) must have been less than or equal to 60 seconds; and no specimen can have flamed or glowed up to the holding clamp; and the cotton indicator cannot have been ignited by flaming particles or drops. To achieve a rating of V-2, the afterflame times t1 and t2 for each individual specimen must have been less than or equal to 30 seconds; and the total afterflame time for all five specimens (t1 plus t2 for all five specimens) must have been less than or equal to 250 seconds; and the second afterflame time plus the afterglow time for each individual specimen (t2 + t3) must have been less than or equal to 60 seconds; and no specimen can have flamed or glowed up to the holding clamp; but the cotton indicator can have been ignited by flaming particles or drops. To achieve a rating of HB, the material must not have a burn rate that exceeds 40 mm per minute over a 75 mm span for specimens having a thickness of 3 to 13 mm, or have a burn rate that exceeds 75 mm per minute over a 75 mm span for specimens having a thickness less than 3.0 mm in a horizontal burning test. If the material ceases to burn before the 100 mm reference mark, an HB rating can also be obtained. 22SHPP0027-WO-PCT (SS230141PCT) [0085] Carbon Footprint of each composition was characterized according to Intergovernmental Panel on Climate Change (IPCC) methodologies (IPCC 2013 GWP100a V1.03). [0086] Compositions and test results are shown in Table 4. In Table 4, the amount of each component is provided in weight percent, based on the total weight of the composition. Table 4
