    Optional Additives

    [0159] As stated, in some embodiments, the capstock includes one or more optional additives. In some embodiments, the optional additive includes one or more of a colorant, pigment, plasticizer, lubricant, UV stabilizer, light stabilizer, thermal stabilizer, antioxidant, antistatic agent, flame retardant, filler, fiber, processing aid, biocide, surfactant, blowing agent, foaming agent, wax, and/or combinations thereof.

    [0160] With reference to the drawings, FIG. 1 is a schematic cross-sectional view of a building material, in accordance with some embodiments of the invention. As FIG. 1 shows, in some embodiments, the building material 100 is a composite board, including a capstock 10 and a core 20. In some embodiments, the capstock 10 at least partially covers one or more surfaces of the core 20, such as a top surface 21, a bottom surface 22, a first side surface 23, and a second side surface 24. It is of course understood that the building material may be oriented such that any outer surface may be designated as top, bottom, and side depending on the specific orientation. Thus, in some embodiments, the capstock covers an outer surface of the core 20.

    [0161] FIG. 2 is a block diagram of a method of forming the building material, in accordance with some embodiments of the invention. As FIG. 2 shows, in some embodiments, the method includes obtaining formulations for the capstock and the core, as represented by block 210. As the figure also shows, in some embodiments, the capstock is coextruded with the core, as represented by block 220. In some embodiments, coextrusion results in opposite ends of the core being uncovered, while other outer surfaces of the core are covered by the capstock.

    [0162] Referring to FIG. 3, shown is a schematic diagram of a block copolymer having alternating hard and soft segments. In some examples, a thermoplastic elastomer may include a block copolymer having alternating hard segments formed from polyester and soft segments formed from polyether or polyester.

    [0163] FIG. 4 illustrates the evolution of torque measured in test pellets of capstock material with different compositions as a function of time and temperature. The choice of thermoplastic elastomer or plasticizer in the capstock formulation may influence both the extrusion characteristics and the long-term stability of a composite article. The torque data were measured in accordance with ASTM D2538 and provide an indication of viscosity and thermal stability.

    [0164] As used herein, dynamic thermal stability (DTS) may be evaluated in terms of the length of time a material remains stable before degradation occurs. This is indicated by a sudden, sharp rise in the torque curve as the material starts to break down and cross-linking occurs. Degradation generally occurs gradually, with color changes typically appearing first as chromophores, such as double bonds forming in the PVC backbone, develop. These color changes precede the onset of catastrophic cross-linking, which is indicated by a sharp increase in torque.

    [0165] Referring to FIG. 4, upward trending of the curves for the TPU and polymeric plasticizer materials approaching the conclusion of the test is indicative of cross-linking during thermal degradation. In the case of the non-TPU TPE compositions, however, no upward trend was observed. Rather, the non-TPU TPE materials surprisingly demonstrated a slight downward inflection possibly indicative of chain scission, followed by a long running substantially flat line indicative of improved thermal stability. Co-polymer thermoplastic elastomers generally imparted greater extrusion torque than TPU at equivalent loading.

    [0166] In some embodiments, a capstock composition exhibits a torque increase of less than 15% from its minimum measured value over the course of the test. That is, the torque measured subsequent to the test's minimum measured value increases by less than 15% from the minimum value. This metric provides a quantitative indication of the material's resistance to thermal degradation, with a lower percentage increase in torque reflecting greater thermal stability and processability under extrusion conditions. In some embodiments, the increase in torque from the minimum measured value may be 0, 1, 2, 4, 5, 10, or 15%, including ranges between any of the foregoing values. In some embodiments, the duration of the test is at least 5 min, e.g., 5, 10, 15, 20, 25, or 30 min, including ranges between any of the foregoing values.

    [0167] In FIGS. 4-9, the samples identified as TPE1 include a polyester elastomer having a Shore D hardness of approximately 60, the TPE2 compositions include a polyester elastomer having a Shore D hardness of approximately 40, and the TPE 3 compositions include a polyester elastomer having a Shore D hardness of approximately 25.

    [0168] FIG. 5 is a plot showing Taber abrasion results for example capstock materials. The data show the weight loss of each capstock sample after undergoing abrasion testing, which serves as a measure of the material's resistance to wear.

    [0169] Referring to FIG. 6, shown is the moisture whitening behavior for various example capstock materials. The graph illustrates the change in lightness (Delta L) of the capstock surface following water immersion, which is indicative of moisture whitening resistance. The results highlight the impact of the selected thermoplastic elastomer or plasticizer materials on a capstock's ability to maintain color stability and resist whitening when exposed to moisture.

    [0170] FIG. 7 is a plot showing surface hardness data for composite articles having a capstock layer formed from example capstock materials. The data include Shore D hardness values for extruded strips, providing a measure of the capstock's resistance to indentation and its overall rigidity.

    [0171] FIG. 8 is a plot showing specific gravity data for example capstock compositions. The plot includes measured specific gravity values for various capstock formulations, which reflect the density of the material and can influence coverage as well as weight of a composite article.

    [0172] FIG. 9 is a plot showing surface gloss at 60 for composite articles having a capstock layer formed from example capstock materials. The plot displays gloss values measured on extruded strips, which indicate the surface reflectivity and visual appearance of the capstock.

    Comparative ExamplesASTM D4060-19 Testing

    [0173] In accordance with ASTM D4060-19 Standard Test Method for Abrasion Resistance of Organic Coatings, four capstock materials were manufactured. Each of the materials included the indicated weight percentage of the following components, based on the total weight of the capstock: 39.1 wt. % of PVC, 24.7 wt. % of ASA, and 18.2 wt. % of SAN, with the remaining 18 wt. % of a thermoplastic elastomer or polymeric plasticizer. The thermoplastic elastomer or polymeric plasticizer for each of the capstock materials is as set forth in Table 1.

    TABLE-US-00001 TABLE 1 Capstock Thermoplastic Elastomer or Polymeric Material No. Plasticizer present at 18 wt. % 1 TPU 2 Terpolymer 3 Thermoplastic copolyester elastomer 4 SIBS

    [0174] Referring also to FIG. 5, evaluation after testing indicates the following weight loss for each of these materials, as set forth in Table 2.

    TABLE-US-00002 TABLE 2 Capstock Material No. Weight loss (grams) 1 0.23 2 0.17 3 0.20 4 0.21

    [0175] Thus, each of the capstock materials with thermoplastic elastomers other than TPU performed better than the capstock material with TPU as the thermoplastic elastomer.

    Comparative ExamplesDow Water Immersion-Moisture Whitening Testing

    [0176] In accordance with the Dow Water Immersion-Moisture Whitening Testing procedure, four capstock materials were manufactured. Each of the materials included the indicated weight percentage of the following components, based on the total weight of the capstock: 39.1 wt. % of PVC, 24.7 wt. % of ASA, and 18.2 wt. % of SAN, with the remaining 18 wt. % of a thermoplastic elastomer or polymeric plasticizer. The thermoplastic elastomer or polymeric plasticizer for each of the capstock materials is as set forth in Table 1 above.

    [0177] With reference also to FIG. 6, evaluation after testing indicates the following delta L for each of these materials, as set forth in Table 3.

    TABLE-US-00003 TABLE 3 Capstock Material No. Delta L 1 0.57 2 0.31 3 0.47 4 0.08

    [0178] Thus, each of the capstock materials with thermoplastic elastomers other than TPU performed better than the capstock material with TPU as the thermoplastic elastomer.
